Science popularization of environmental protection rejects "invisible pollution"-past lives polluted by noise.

sound pollution

environmental noise

Environmental noise refers to the sound that interferes with the surrounding living environment in industrial production, building construction, transportation and social life.

Environmental noise is a regulation on the allowable range of noise in order to protect people’s health and living environment. The basic standard of environmental noise is the basic basis of environmental noise standard. Most countries refer to the base recommended by the International Organization for Standardization (ISO) (for example, sleep 30 decibels) and make it according to their own and local conditions.

Auditory decibel

0 ~ 10 dB: lower hearing limit

10 ~ 20 decibels: extremely quiet

30 ~ 40 dB: Very quiet.

40 ~ 50 dB: Quiet.

50 ~ 60 dB: relatively quiet.

70 ~ 80 decibels: relatively noisy.

80 ~ 90 dB: Noisy

100 ~ 110 dB: Very noisy.

130 ~ 160 decibels: unbearable

noise criterion

According to different noise sources

There are many noise standards issued in China.

Mainly include

1. GB3096-2008 Quality Standard for Acoustic Environment

2. GB12348-2008 Emission Standard for Environmental Noise at the Boundary of Industrial Enterprises

3. emission standard for community noise (GB22337-2008)

The limits of noise emission at boundary of industrial enterprises are as follows. dB(A)[1]

Day and night

Class 0 50 40

Category 1 55 45

Category 2 60 50

Category 3 65 55

4 categories 70 55

WHO (world health organization) recognizes that

Harm of noise pollution

Second only to air pollution.

This "invisible killer"

The impact on the environment is quite huge.

According to 2014

Published by the World Health Organization and the European Union Cooperative Research Center

According to the report "Disease Burden Caused by Noise Pollution"

Noise pollution not only makes people fidgety.

Affect sleep quality

It may also cause heart disease and learning disabilities.

And tinnitus.

Thereby shortening people’s life span.

Harm of noise to human beings

1. Hearing problems

Our ears can hear a certain range of sounds without being damaged. Man-made noises such as guns, horns, machinery, airplanes and even vehicles are outside the acceptable hearing range of our ears. Continuous exposure to loud noise can easily lead to damage to our eardrums and hearing loss, and also reduce the sensitivity of our ears to sound rhythm; Higher decibel noise can cause temporary/permanent deafness.

2. Mental health problems

Excessive noise pollution will affect mental health. Noise acts on the central nervous system of the brain through the auditory organs, so that it affects all organs of the whole body. Therefore, noise not only damages people’s hearing, but also harms other systems of the human body. Due to the noise, there will be neurasthenia symptoms such as headache, brain swelling, tinnitus, insomnia, general fatigue and memory loss.

3. Physical function problems

Studies have shown that high-intensity noise will lead to an increase in blood pressure and heart rate, interfere with normal blood flow, and lead to cardiovascular diseases for a long time; Noise can also lead to digestive system dysfunction. For children with greater plasticity, life noise will have a greater impact on them, especially on visual organs, endocrine function and normal development of organs.

4. Work and life problems

High decibel noise will lead to misunderstanding in language communication between two people and make them unable to communicate freely; Noise can also distract people’s attention, leading to slow response, easy fatigue, decreased work efficiency and increased error rate.

Different from water, atmosphere and solid waste

Other three recognized urban pollution.

Noise is a sensory nuisance.

Cannot be processed centrally.

Mainly in the absence of pollutants,

Pollution effects are not lasting and will not be accumulated,

Noise source dispersion, etc.

So how to solve the noise pollution?

We have laws and regulations:

↓↓↓

On October 29, 1996, the 22nd meeting of the 8th the NPC Standing Committee passed the Law on the Prevention and Control of Environmental Noise Pollution in People’s Republic of China (PRC).

2018/12/29 The Seventh Session of the 13th the NPC Standing Committee adopted amendments to the Law on the Prevention and Control of Environmental Noise Pollution in People’s Republic of China (PRC).

2021/12/24 The Law on the Prevention and Control of Noise Pollution in People’s Republic of China (PRC) was adopted at the 32nd meeting of the 13th the NPC Standing Committee, and will come into force on June 5, 2022.

As an individual

We can’t completely change the environment.

To eliminate excessive noise.

These things will need to be handed over to

Government, urban planners and other functional departments.

but

While waiting.

There are still some things we can do:

Reject noise

Start from me

Let’s live in a city

More silence.

Less noise

Poisonous Land Incident in Changzhou, Jiangsu Province: School Location, Ambush, Physical Examination of Students, Attention

  Xinhua News Agency, Nanjing, April 19th: The school is located 100 meters away from the "poison land" — — Tracing chemical pollution incidents in Changzhou schools

  Xinhua News Agency reporters Qin Huajiang, Chen Gang and Yang Shaogong.

  On one side is the plot polluted by three chemical plants seven years ago, with an area the size of several football fields; On the one hand, there is a school that has just settled in, and it always smells pungent. There is only one road between the two.

  It should be a safe place to study, but the school site is built next to the "toxic plot"; Should be healthy boys and girls, but the body appears abnormal symptoms such as abnormal blood indexes and leukopenia. Over the past few days, 500 students in changzhou foreign languages school have been suspected of being poisoned by contaminated plots in chemical plants, which has aroused widespread concern in society.

  It should be prudent to build schools in environmentally sensitive areas, but why should schools be built only 100 meters away from the "toxic land"? Why didn’t the EIA warning get attention? Why is there such a big difference between spontaneous physical examination and tissue physical examination? Xinhua News Agency reporters rushed to the local area to investigate.

  The disaster of site selection: the "time bomb" buried seven years ago

  Since the plot is "toxic", why did changzhou foreign languages school choose this site?

  The reporter learned that Changwai is the first choice for many local parents to choose schools because of its high teaching level. Before the relocation in 2015, the original school site could not meet the needs of the school’s reform and development due to the increasing number of students and insufficient teaching and auxiliary resources, and the earthquake-proof coefficient of the house was low, so it needed to be rebuilt.

  And this problem, Changzhou "took a lot of brains." According to the Changzhou Municipal Government, in recent years, the urban population has further gathered in Changzhou High-tech Zone and Industrial Park, and Xinbei District is in urgent need of richer educational resources. The reconstruction and relocation of changzhou foreign languages school in different places can not only ease the traffic pressure on the main roads in the original area of the school, but also greatly improve the overall level and comprehensive strength of education in the northern new city.

  According to the plan made by Xinbei District of Changzhou City, Changwai New Campus is located in the west of Tongjiang Road, south of Liaohe Road and north of Qiandaohu Road (Longhu Street). This plot was originally a Pacific Electric Machinery Factory and a natural village. Although it is not the original chemical plant plot, it is less than 100 meters away from the original chemical plant plot, and the "time bomb" was buried.

  According to the reporter’s investigation, the contaminated plots of original chemical plants include the original sites of Jiangsu Changlong Chemical Co., Ltd., Changzhou pesticide plant, Changzhou Huada Chemical Plant and Changzhou Changyu Chemical Co., Ltd., with a total area of about 26.2 hectares. Because the chemical plant is polluted and smells too strong, the surrounding residents have a strong reaction. As a result, the government ordered enterprises to move into the new district. Since then, this plot has been idle.

  In May, 2009, the relocation of chemical enterprises in this plot started. Complete the relocation of the former Changlong Chemical and other enterprises before June 2011. The project was established in 2013, and the land restoration project was officially implemented in March 2014.

  According to the earlier local planning, the contaminated original chemical plant plot was originally planned to be used for commercial development after restoration, and the restoration project was undertaken by Changzhou Black Peony Construction Investment Co., Ltd. As the design guidance unit of the soil remediation project of the relevant plots, Changzhou Academy of Environmental Sciences originally scheduled to complete the soil remediation in June last year. However, because the cement enterprises that received the pollutants for harmless treatment could not produce normally, there was no clear time for the remediation, but the relevant departments did not make corresponding plans for this change.

  The problem doesn’t stop there. Xu Puqing, president of Changzhou Academy of Environmental Sciences, said that in the process of restoration, the contractor and the constructor should have carried out closed operations according to the plan issued by the relevant departments, but they ended up working in the open air, and the related environmental risks were not controlled.

  Ecological risk: toxic plots are not repaired and schools are built.

  Since it is a "toxic plot", what is the EIA result of the new site of the school?

  According to the reporter’s investigation, the EIA report, which is the basis of the school, was approved on March 31, 2012, but the foundation stone laying time of the school was August 21, 2011, which was questioned as unapproved construction.

  In response, the local authorities responded that the foundation stone was laid before the EIA, but it was not officially started. The specific start time was October 2013, and the project construction was completed in July 2015. After the school met the indoor air quality test standards, it was officially put into use in September 2015.

  The environmental impact assessment report of the New North Campus Project of Changzhou Senior Middle School in Jiangsu Province issued by Changzhou Environmental Protection Research Institute shows that the influence of soil and groundwater pollution in the surrounding sites has become an important hidden danger to the school environment.

  According to the report, the soil and groundwater of the original site of Changlong (Huada, Changyu) Company in the north of the project have been polluted, and there are human health risks and ecological risks. At the same time, it is suggested that air pollution will occur after the restoration of the original site of Changlong and other chemical plants. If the school is put into use before the restoration and acceptance of the site, it will have an impact on the health of teachers and students at school. According to the Changzhou Municipal Government, since late December, 2015, soil remediation in the former Changlong, Huada and Changyu chemical blocks on the north side of changzhou foreign languages school has given off peculiar smell.

  In fact, the school started construction as early as October 2013 and was officially put into use in September 2015. This shows that the site selection of the school will be built before the land is repaired, and the relevant departments have not paid attention to the possible pollution; The restoration of contaminated plots that should have been completed before the school starts was unexpectedly postponed, but the school relocation plan was not adjusted and still put into use as usual, resulting in increasing environmental risks.

  Health Debate: Why is there such a big difference between spontaneous physical examination and tissue physical examination?

  Changzhou foreign languages school is the first choice for many local parents because of its high teaching level. But since the end of last year, this school has become a nightmare for many students and parents.

  "I am worried every day, and my daughter has checked out lymphadenopathy." A parent of a student surnamed Qin told the reporter that in December last year, the surrounding original chemical plant plot was dug up and repaired, and the pungent smell became heavier and heavier, and the child developed symptoms such as drowsiness and dandruff. On January 10th or so, his daughter was diagnosed with lymphadenopathy. After more than a month, she was examined again, and one side was reduced to half of the original, while the other half remained unchanged.

  A "Summary Table of Voluntary Physical Examination Results of Grade 7-8 Students in changzhou foreign languages school" signed by changzhou foreign languages school, Chairman of the Board of Directors and President of Changzhou Middle School in Jiangsu Province, on March 11th shows that among 641 samples, 493 people have abnormal symptoms such as dermatitis, eczema, bronchitis, abnormal blood indexes and leukopenia.

  In response to the abnormal situation of students’ examination indicators, the Changzhou Municipal Government said that it organized an expert group to conduct a special analysis, and the relevant test data was quite different from that provided by parents, but there were more than 100 abnormal indicators. According to the data put forward by the medical expert group organized by Changzhou Municipal Health Planning Commission, from January 11th to February 29th at 9: 00 am, there were 597 out-of-hospital students in eight hospitals in the city, and 133 of them had abnormal examination indexes, including 71 thyroid nodules, 22 cervical lymphadenopathy, 17 thyroid nodules with cervical lymphadenopathy, 5 abnormal liver functions, 8 abnormal renal functions, 3 bronchitis, 2 thyroiditis and left inguinal lymph nodes.

  In response to parents’ report that some students were suffering from lymphoma due to contaminated land, Hua Fei, head of the medical expert group of Changzhou Health Planning Commission and vice president of Changzhou First People’s Hospital, said that one case was diagnosed before the school moved and is currently being treated.

  In a joint letter written by "all parents in changzhou foreign languages school" to "leaders of governments at all levels, environmental protection, education and letters and visits departments" on January 8th, parents questioned "which is more important: children’s health or project development".

  The Ministry of Education and the Ministry of Environmental Protection attach great importance to the environmental pollution around changzhou foreign languages school, Jiangsu. The Ministry of Environmental Protection and the Jiangsu Provincial Government have set up a joint investigation team and will go to Changzhou for on-site investigation. The Office of the State Council Education Steering Committee has launched a special supervision mechanism for major emergencies in education, and the national inspectors have taken the lead in going to the local area for special supervision. The Ministry of Environmental Protection said that the relevant information will be announced to the public in a timely manner after the investigation. According to the Ministry of Education, the supervision team will announce the relevant supervision situation in a timely manner to effectively safeguard the physical and mental health of students.

  The reporter will further follow up the progress of the chemical pollution incident in Changzhou schools.

  During the May 1 ST period, the volume of express delivery in Beijing increased by nearly 60% year-on-year, and that in Chengdu and Xi ‘an increased by nearly 70%. In this regard, Jingdong Logistics said that on the eve of May 1 ST, the emergency response level of public health emergencies in Beijing was lowered, and the courier brother was allowed to use the Jiankang code to register and enter the community, and the number of home delivery orders during the holidays increased to a certain extent.

  After the unsealing in Wuhan, the number of express delivery orders also increased rapidly. According to the data of Jingdong Logistics, the volume of express delivery in Wuhan increased by 80% during the May Day period. According to the data of JD.COM, before Wuhan was unsealed on April 8, the express delivery volume of Jingdong Logistics had been restored to the same period of last year, and "ordering before going to bed and waking up to receive goods" had been normalized.

  From the Spring Festival to Qingming and then to May Day, online consumption in the three major holidays has been in a growing trend, which is the main engine of consumer recovery.

It is suggested that the key population be vaccinated with these vaccines, the latest bulletin from National Health Commission!

Yesterday (December 10th), the National Health and Wellness Commission held a press conference and invited relevant experts to introduce the prevention and treatment of respiratory diseases in winter in China. What measures should schools, kindergartens and other institutions take to prevent the spread of respiratory diseases, and should they be vaccinated after they have recovered from cold symptoms? Understand the article ↓↓↓

The overall amount of diagnosis and treatment of respiratory diseases in children fluctuated and decreased.

Mi Feng, spokesperson of the National Health and Wellness Commission, said that at present, the overall amount of diagnosis and treatment of children’s respiratory diseases in medical institutions above the second level in the country has shown a downward trend, and the increase in pediatric diagnosis and treatment in some large children’s specialist hospitals and general hospitals has been alleviated.

Judging from the overall situation of fever clinics and emergency departments, the number of patients with respiratory diseases in China has been relatively stable in recent days, especially in primary medical institutions. The overall normal medical services in the country have not been affected.

What is the progress of influenza vaccination in China?

Xia Gang, director of the Department of Health and Immunity of the National Bureau for Disease Control and Prevention, said that this year’s influenza vaccine supply has the following characteristics:

First, the supply is early. Since July, vaccination units around the country have started influenza vaccination services one after another, earlier than the influenza epidemic season.

Second, the vaccine supply is sufficient. This year, the production and supply of influenza vaccine has increased significantly compared with last year, and it can meet the vaccination needs of the masses at this stage.

The third is to re-implement. Dispatch and deploy many times to guide all localities to actively promote the vaccination of influenza vaccine in accordance with the principle of informed consent.

three

What measures do key institutions and places take to prevent it?

Peng Zhibin, director of the Department of Respiratory Infectious Diseases of the Infectious Diseases Management Office of China CDC, said that schools, kindergartens, public transport and other areas are densely populated and relatively closed inside, and are key institutions and places for the prevention and control of respiratory infectious diseases.

For schools and child care institutions

First, we should vaccinate in time as soon as possible. Students, faculty and staff should carry out influenza vaccination as soon as possible to improve their own immune barrier and reduce the risk of illness;

Second, it is necessary to strengthen environmental cleanliness, maintain indoor hygiene, regularly open windows for ventilation, maintain indoor air flow, and improve classroom air quality. However, the outdoor temperature is low in winter and spring, and attention should be paid to keeping warm during window ventilation;

Third, it is suggested to strengthen health monitoring, do a good job in morning and afternoon check-ups, absenteeism registration, etc. Students and faculty members are advised not to go to work with illness to prevent infectious diseases from being introduced into schools or classrooms.

For public transport

First, it is necessary to do a good job in cleaning and disinfecting the interior of vehicles, and ventilate regularly to ensure the air quality inside vehicles;

Second, it is suggested to wear a mask in the high incidence season of respiratory infectious diseases to reduce the risk of exposure and illness and be the first person responsible for your own health.

How to strengthen protection for young children and the elderly?

Peng Zhibin introduced that winter and spring are the high season of respiratory infectious diseases, the immune system of young children is still not perfect, and the immune function of the elderly is relatively weak. On the basis of maintaining good personal hygiene habits and clean environment, it is necessary to focus on strengthening the following protective measures:

The first is to carry out vaccination as soon as possible. Vaccination can effectively reduce infection and reduce the risk of severe diseases, which is the most effective and economical means to prevent infectious diseases. Young children and the elderly should be vaccinated against COVID-19, influenza and pneumococcus as soon as possible.

Second, young children and the elderly should try to avoid going to places with closed environment and crowded people. When it is really necessary to go, they should wear masks scientifically to reduce the risk of respiratory infectious diseases.

The third is to strengthen the daily health monitoring of young children and the elderly. When there are symptoms of respiratory infectious diseases such as fever and cough, they should seek medical advice as soon as possible and use drugs scientifically and safely according to the doctor’s advice.

In addition, when other family members have respiratory infectious diseases, they should try to avoid close contact, especially to avoid contact with young children and the elderly at home. When children whose family members have symptoms of respiratory infectious diseases such as fever and cough go to the hospital, they should also protect themselves and avoid cross-infection.

five

Are you still vaccinated after you have recovered from cold symptoms?

Xia Gang, director of the Department of Health and Immunity of the National Bureau for Disease Control and Prevention, said that if flu-like symptoms have already appeared, it is recommended to continue to vaccinate against influenza after the diagnosis is not confirmed and self-healing. There are two reasons:

First, the symptoms of respiratory tract infection are not specific, and many pathogenic infections may have flu-like symptoms such as fever and headache. However, such symptoms are not necessarily infected with influenza virus, but may also be infected with other pathogens, the most common being the common cold.

Second, there are many types (except A, there are B) and subtypes (A has H1N1 subtype and H3N2 subtype) of influenza virus, which can cause epidemic. After being infected with a certain type or subtype, there will be the risk of getting other types or subtypes of influenza. Influenza vaccine is a multivalent vaccine covering many different types and subtypes, and trivalent and tetravalent vaccines are usually used. If you are vaccinated after being infected with a certain type of influenza (such as A), the components of other types of influenza (such as B) contained in it can still play a role in preventing this type of influenza. In addition, in the same epidemic season, different types and subtypes are commonly prevalent. For example, at present, subtype A (H3N2) is dominant, followed by influenza B.. In the past, in the same epidemic season, the dominant strains gradually changed from one type to another.

Therefore, even if you have had cold symptoms recently, it is recommended to get flu vaccine as soon as possible after recovery, especially for key people such as the elderly. Vaccination with flu vaccine can reduce infection and reduce the risk of serious illness and death.

On the effectiveness and safety of influenza vaccine

Peng Zhibin, director of the Department of Respiratory Infectious Diseases of the Infectious Diseases Management Office of China CDC, said that people’s understanding of the harmfulness of diseases, the safety and effectiveness of vaccines all affect their willingness to vaccinate. Peng Zhibin responded to three questions at the press conference:

First of all, about the dangers of influenza. Influenza is not a common cold, but an acute respiratory infectious disease caused by influenza virus. People are generally susceptible to influenza virus, and high-risk groups such as infants, the elderly and patients with chronic diseases are more harmful after being infected with influenza, and may have serious complications such as pneumonia.

Secondly, about the effectiveness of influenza vaccine. Scientific research and vaccination practice have fully proved that influenza vaccination is effective. For the elderly who are at high risk of becoming seriously ill after being infected with influenza, influenza vaccination can effectively reduce the incidence of influenza and the incidence of influenza-related complications in the elderly. Some researchers have made a comprehensive analysis of 95 studies on the protection effect of influenza vaccine in the world. The results show that in the flu season, after the elderly are vaccinated with influenza vaccine, the flu-like symptoms can be reduced by 39%, the confirmed flu can be reduced by 49%, and the flu-related complications can be reduced by 28%.

Taking another key population, children and adolescents, as an example, influenza vaccination can effectively reduce the incidence of influenza in school-age children, and can also reduce absenteeism from school due to influenza. Research conducted in Beijing shows that large-scale centralized vaccination of influenza vaccine for primary and secondary school students can reduce the risk of influenza concentrated fever by 50%-89%. The research carried out in Shenzhen shows that the high vaccination rate of influenza vaccine can effectively reduce the risk of absenteeism, and the preventive effect on absenteeism is 53%.

Third, about the safety of vaccines. Influenza vaccine has been used in the world and China for decades. It is a mature vaccine with good safety.

seven

These vaccines are also recommended for key populations.

Xia Gang said that in addition to influenza vaccination this winter and next spring, pneumococcal vaccine and Covid-19 vaccine are also recommended for the elderly and people with chronic basic diseases;

For children, it is suggested that on the basis of continuing to do a good job in immunization planning vaccination, non-immunization planning vaccines such as pneumococcal vaccine and Haemophilus influenzae type B conjugate vaccine can also be vaccinated.

No matter whether it is an immunization program vaccine or a non-immunization program vaccine, the requirements of vaccination specifications should be strictly followed during the vaccination process.

In the second quarter of fiscal year 2025, the revenue increased by 5%. Taotian "double 11" won, and Ali’s confidence in the future came back.

  Double 11 just closed. On November 15th, Ali (HK09988, share price of HK$ 87.20, market value of HK$ 1.67 trillion) handed over the report card of the second quarter of fiscal year 2025 (the quarter ending September 30th, 2024).

  The financial report shows that in this quarter, Ali’s income was 236.503 billion yuan, up 5% year-on-year, and the net profit attributable to ordinary shareholders was 43.874 billion yuan.

  In the e-commerce business that has attracted much attention, in this quarter, the growth of GMV on Amoy Antenna was driven by the double-digit year-on-year growth of order volume, which was mainly driven by the increase of purchase frequency and partly offset by the decrease of average order amount.

  In addition, Ali also mentioned the achievements of this year’s "double 11". During this year’s "double 11", Taobao Tmall GMV achieved strong growth, and the number of buyers reached a record high.

  For this financial report, Wu Yongming, CEO of Ali Group, said that this quarter, Taotian business continued to invest in user experience and enrich product supply to better serve consumers. He said that he has more confidence in the prospect of core business than in the past, and will continue to invest to support long-term growth. The operating efficiency of other businesses continues to improve, and most businesses continue to improve profitability or reduce losses.

  It is worth mentioning that in this quarter alone, Ali has made a lot of moves in the e-commerce business. Since September 1st this year, Taotian began to charge the basic software service fee based on GMV for transactions on the platform. In July, Taobao announced the optimization of the "refund only" strategy. In addition, this quarter, Taotian also cancelled and refunded the annual fee of merchants, and improved the operating efficiency of merchants through "all-site promotion". This series of actions may indicate that Taotian has a new strategic direction in e-commerce business.

  It is worth mentioning that this quarter’s financial report shows that Alibaba continued to buy back shares, and this quarter invested 4.1 billion US dollars to buy back 414 million common shares, and the outstanding shares further decreased by 2.1% compared with the end of June.

  Increase investment in e-commerce business: have high expectations for the growth of Taotian users.

  As far as this quarter is concerned, Ali is increasing investment in domestic and overseas e-commerce business and has made many layout actions.

  As far as Taotian Group is concerned, the financial report mentioned that this quarter, Taotian increased investment in strategic measures such as goods with competitive prices, customer service, membership system rights and technologies, aiming at improving the user experience. These measures have brought higher purchase frequency and better feedback on the overall shopping experience than the same period last year.

  At the analyst conference call that night, Ali executives stated in detail that for Taobao Tmall platform, the current strategy is to increase investment in the whole user experience and business side while improving profitability. "In terms of investment, there will be many ways. First, we will broaden the supply advantages, such as price power, new products and brands with competitive advantages, and we will also provide users with a better user experience."

  He also mentioned that he will continue to invest in the technology platform, especially in the computing power investment of e-commerce. There are many AI-related products under development, and these AI-related products will need to use relatively strong AI computing power.

  In addition, Ali further mentioned the value of 88VIP in the financial report. According to him, 88VIP members are the consumer groups with the highest purchasing power, and their number continued to increase by double digits year-on-year this quarter, reaching 46 million.

  Ali mentioned that high-end consumers are loyal customers who can increase the frequency of purchase and promote the growth of GMV. Therefore, it is committed to continuously increasing the number of 88VIP members by enhancing the investment in membership rights and services.

  It is worth mentioning that in September, Taobao announced that it would gradually open WeChat payment to all Taobao Tmall merchants after September 12.

  In this regard, in the analyst conference call, Ali executives said that after accessing WeChat payment, they have high expectations for user growth and will make relatively medium-and long-term investment in user growth and retention. "The future is a relatively large investment direction." He said that Taotian is still in the investment period at this stage, and will continue to pay attention to investment efficiency at this stage, and at the same time make better and greater investments by improving CMR.

  It is worth mentioning that, in this quarter, Taotiantian is trying to better balance the relationship with merchants, regardless of the direction of collecting basic software service fees based on GMV, loosening the "refund only" and investing, and has made a lot of efforts to improve the experience of merchants on the platform. In this year’s "double 11", Taotian is no longer blindly "rolling in low prices", and its attention to middle and high-end consumers such as 88VIP is also rising, which shows that it is competing with Pinduoduo’s low-price route in a dislocation way.

  In this conference call, Ali executives mentioned: "I think this year is a turning point. For brand owners, they will really choose a platform that can bring them more sales, rather than simply putting in a growth. Under this circumstance, Taobao Tmall’s advantage in obtaining brand budgets will expand in the future. "

  According to the financial report, the customer management revenue of China retail business of Taotian Group increased by 2% year-on-year, mainly due to the growth of online GMV.

  In the overseas e-commerce business, Ali’s investment is still not small. In this quarter, the revenue of Ali International Digital Business Group increased by 29% year-on-year, and the economic benefit of AliExpress Choice business unit improved month-on-month.

  However, in this quarter, the adjusted EBITA (profit before interest, tax and amortization) of the international digital business group was a loss of RMB 2.905 billion, compared with a loss of RMB 384 million in the same period of 2023, which was mainly due to the increase in investment in AliExpress and Trendyol’s cross-border business, partly offset by the significant reduction in operating losses caused by the improvement of Lazada’s liquidity rate and operational efficiency.

  Affected by cross-border business, rookie revenue increased by 8% year-on-year to 24.647 billion yuan this quarter, mainly due to the growth of cross-border logistics service revenue.

  While increasing investment in e-commerce business, the financial report shows that in this quarter, the losses of local life group and big entertainment group both narrowed year-on-year, and the business operation efficiency was optimized in a planned and rhythmic manner. At the same time, hungry, high-tech orders increased, and business scale increased.

  Will e-commerce turn from "low price war" to "AI war"?

  In this quarter’s financial report, the presence of AI is still not low.

  Ali’s financial report mentioned that focusing on the integrated development of "Cloud +AI", Alibaba Cloud’s commercial income growth accelerated, and its quarterly income increased by 7% year-on-year. It is worth noting that it continues to be driven by the double-digit growth of public clouds, and the revenue of AI-related products has achieved three-digit year-on-year growth for five consecutive quarters; Adjusted EBITA increased by 89% year-on-year.

  On the conference call, Ali executives even said: "We believe that the prelude of the AI ? ? era has only started at a high level, and it is still in the early stage of API reform. The imagination of AI for the future will not be limited to mobile phone screens, but will reshape the digital world, which will eventually affect or even change all walks of life in the physical world."

  According to the reporter’s understanding, Ali’s "AI-driven" strategy has been launched for one year, and many businesses under Ali have launched AI. In the e-commerce business alone, many products have been launched.

  When Ali released this financial report, he mentioned that Taobao launched AI products as "business stewards" for all businesses. This year, "double 11" has served 4 million businesses and helped small and medium-sized businesses generate more than 100 million products and marketing materials. Ali also mentioned that the penetration rate of the AI-driven marketing tool "all-site promotion" has steadily increased, helping businesses to improve marketing efficiency and further improve the level of commercialization in a rhythm.

  In addition, on October 28th, Ali International Station comprehensively upgraded AI foreign trade products. According to the data provided by Ali International Station, at present, more than 60,000 small and medium-sized enterprises around the world are using the AI products of Ali International Station, and the scale of products released by AI has reached 7 million. Recently, Ali International also launched Accio, the world’s first AI Search engine in B2B field, which is open to global businesses and officially entered the AI Search circuit.

  According to reports, users can use "vernacular" to ask about AI and put forward demands. Accio will take the initiative to sort out and understand what users really want through many rounds of dialogues, and disassemble demands, investigate the market and give suggestions through professional B2B industry knowledge, so as to screen suppliers and recommend goods more accurately, and provide one-stop intelligent procurement services like a truly professional agent.

  In fact, many platforms have launched AI search products recently. Will the emergence of AI products bring new changes to the e-commerce world?

  Pan Helin, a member of the Information and Communication Economy Expert Committee of the Ministry of Industry and Information Technology, told the national business daily that AI search has two functions, one is to help users find answers to some difficult questions or search links. Another function is to guide the links that Ali and Tik Tok want users to see in the optional search results. Therefore, this can bring traffic to e-commerce and content platforms, which is a new idea for e-commerce development at present.

  In the eyes of the industry, the changes that AI can bring to the e-commerce world are indeed not only as simple as reducing costs and increasing efficiency. Zhuang Shuai, the founder of Bailian Consulting, told national business daily that AI is reshaping e-commerce. In his view, AI can not only (enhance) the attractiveness of merchants, but also bring about changes in profit model (service income can be greatly improved), and improve the efficiency of new product research and development, improve differentiated supply and reduce price competition.

  It is worth mentioning that while successively launching AI products and rushing to invest in AI startups, there has even been a war of grabbing people between Internet platforms.

  On November 13th, according to the science and technology innovation board Journal, it was reported that Zhou Chang, a former employee of ali tong Yida Model, had violated the non-competition agreement, and Ali had sued and submitted an application for labor dispute arbitration. After Zhou Chang left his post in July this year, some media reported that Zhou Chang had joined Byte in August to work on AI big model. In the long run, after the low-price war, the AI ? ? war between major Internet will also affect the ranking of major e-commerce platforms in the e-commerce world.

  For Ali, the whole fiscal year of 2025 is over half, and the highlight "double 11" has also ended. Under the leadership of the management, Taotian has made a shift in business strategy and further interconnection, but on the whole, Ali is still increasing investment in e-commerce business, and it is still inconclusive how many positive effects these new measures can bring to Taotian, which was originally trapped in stock competition. However, judging from the external expression of the management, after a short period of reflection, Ali’s confidence in the future has returned.

High-growth enterprise | Titan Intelligence: Independent innovation regains the right to speak in the industry, and intelligent charging equipment covers 195 countries around the world.

Feng Yuyi, a trainee reporter of Southern Finance and Economics, reports from Zhuhai.

In the era of Industry 4.0, AGV/AMR (Mobile Robot for Industrial Application) has become a vital part of industrial production intelligence, and gradually penetrated into manufacturing, logistics and service industries, and the charging industry promoted by this is in the cusp of vigorous development.

At present, the 100 billion-level charging and power market formed by new energy industrial vehicles such as mobile robots, mining machines, low-speed unmanned vehicles and lithium-ion forklifts, as well as the continuation market of secondary sales of charging modules, power batteries and replacement of charging equipment, are accelerating.

According to the forecast of AGV/AMR industry alliance, it is estimated that the new AGV/AMR in China will exceed 120,000 units in 2023, and the new market will exceed 200,000 units in 2025, with a market scale exceeding 45 billion yuan. The compound growth rate of sales in the next five years will remain above 40%. Among them, AGV/AMR charging and power system are two important systems of electric industrial vehicles, accounting for over 8%.

"Electrification and intelligentization of industrial vehicles are the general trend. Even though industrial manufacturing has faced various difficulties in the past three years, the AGV/AMR charging industry is still in a period of rapid growth with strong demand and full of resilience. With the diversified application scenarios of mobile robots, the penetration rate of the charging industry will be further improved. " Recently, Zou Jianjun, founder, chairman and CEO of Guangdong Titan Intelligent Power Co., Ltd. (referred to as "Titan Intelligent"), said in an interview with Southern Finance and Economics all-media reporter.

Founded in 2016, Titan Intelligence is a state-level specialized and new "Little Giant" enterprise focusing on providing overall energy solutions and back-end data services for new energy industrial vehicles. In the context of rising industry demand and maturing technology, Titan Intelligent won the A round of financing from Zhuoshi Investment in 2022.

Compete for product pricing power

At the beginning of Titan Intelligent’s entry into the new track, it coincided with the wave of "oil to electricity" and "lead to lithium" for industrial vehicles. Under the market reform dividend brought by the "double carbon" background, Titan Intelligent stood out and quickly opened the market with its research and development capabilities and market sense.

When talking about why the track was chosen, Zou Jianjun said, "In the process of a customer chat, it was found that the AGV/AMR charging industry is generally a’ one-price’ sale, which is completely a market where the seller has the pricing power." After market research, he found that the domestic AGV/AMR and the charging products of electrified industrial vehicles were almost all imported from abroad. Although the domestic market demand was huge, there was no bargaining power.

After gaining insight into this new market trend, Titan Intelligent accelerated its layout research and development with AGV/AMR and intelligent lithium-ion charging equipment and batteries for electrified industrial vehicles as the main business, and the annual investment in research and development accounted for about 10% of its main business income. In a few years, Titan Intelligent Power has successively launched the digital intelligent charging series for industrial electric vehicles, the side charging and charging integrated machine series for intelligent manipulator of mobile robots, the power battery series for mobile robots, the power battery series for low-speed unmanned vehicles, the power charging series for low-speed unmanned vehicles, wireless charging for mobile robots and other efficient and stable overall charging solutions. The application scenarios involved run through all links of the whole industrial chain, and cover application places such as logistics and transportation, smart home appliances and public infrastructure.

"Although we started later than foreign countries, relying on China’s R&D foundation and industrial chain advantages in the field of new energy charging, we quickly mastered the right to speak in the industry in the game with foreign products, let the price return to a reasonable range, and achieve the domestic market share. First." Zou Jianjun said that more and more foreign manufacturers began to choose to use Titan smart products.

According to reports, while entering the mainstream AGV brand manufacturers in China, including Hangcha Group, Heli Forklift, Kuka Robot, Xinsong Robot, BYD, etc., Titan Intelligence has also obtained international qualification certifications such as cTUVus and CE, and is exported to 195 countries and regions such as America, Europe, Africa, Southeast Asia and Australia, reaching a global coverage rate of 85%. Internationalization has become one of the ideas of Titan’s intelligent "by going up one flight of stairs". Zou Jianjun said, "The forklift truck for lithium battery industry is our important market. 70%-80% of the demand is overseas. Expanding business overseas is equivalent to catching this blue ocean market."

According to the data of Chinafork. com, the global forklift market will be about 150 billion yuan in 2022, including 110 billion yuan in overseas market and 40 billion yuan in domestic market. Domestic forklifts mostly use lithium battery as the main power, and the trend of replacing lead-acid battery forklifts in foreign markets has accelerated significantly, or it will usher in important development opportunities.

With the iterative upgrading of new energy battery technology, it also brings more room for improvement for the mobile robot industry, and is highly expected in reducing costs, improving efficiency, and industrial transformation and upgrading.

Based on long-term observation of the market, Zou Jianjun bet on lithium iron phosphate battery. Titan Intelligent established a subsidiary-Zhuhai Titan Lineng Technology Co., Ltd., and has its own PACK factory, which mainly develops and produces AMR and AGV power lithium battery packs, further improving the overall solution of the power system.

In Zou Jianjun’s view, compared with traditional lead-acid batteries, lithium batteries have the advantages of lighter weight, smaller volume and higher energy density, so the lithium battery forklift model is more compact and the vehicle stability is higher. "And in recent years, the acceptance of lithium battery forklifts by end customers, especially high-end customers, has steadily increased. We believe that the future development prospects of the lithium battery market are very broad."

Explore and create a new model of "energy products+data services"

Walking into the research laboratory of Titan Intelligence, the wireless charger, which is called the "charging treasure" of the mobile robot, is executing the command set by the wireless energy emitting device, and automatically recognizes charging from a distance after finishing the workflow. A series of actions are flowing, and fully automatic and intelligent charging can be realized without connecting vehicles.

This is the research and development site of Titan Intelligent’s autonomous intelligent AGV charging system based on magnetic coupling resonant wireless charging technology, which has no electrode oxidation and fouling, reduces the charging accident caused by poor electrode contact, not only improves the safety and applicability, but also makes AGV charging products more intelligent.

Zou Jianjun revealed that the high-power wireless charger series independently developed by the company has built technical barriers in coil design, circuit research and core algorithm. At present, it has completed the verification in the laboratory stage and will go to the stage of commercialization and mass production next year. "The era of wireless charging has arrived, and it is expected that there will be an outbreak in the next five to ten years."

Compared with wireless charging of electric vehicles, AGV wireless charging requires fast charging mode with low voltage and high current, and the main challenge is to require small size, high efficiency and high cost performance. Zou Jianjun introduced, "We combine AGV battery and wireless charging to build an overall AGV power system, realize modular development, reduce the volume by 50%, and continuously improve the product stability, which is our design idea and core competitiveness to fundamentally reduce costs."

At present, the industrial wireless charging technology track targeted by Titan Intelligence is becoming increasingly hot at home and abroad. According to the incomplete statistics of Southern Finance and Economics reporters, there are already manufacturers in the domestic market, such as Baiyi Technology, Luyu Energy, Avant-garde Wireless, Qingdao Paworth, Taihang Jiaxin Electric, etc., who have laid out new technologies, and new scenes and new applications are constantly opening up. In foreign markets, Tesla announced in June this year that it plans to acquire Wiferion, a German manufacturer that provides wireless charging technology for AGV/AMR.

While Titan Smart continues to increase its research and development of wireless charging systems, the team is constantly exploring innovations in business models.

In recent years, with the blessing of AI, mobile robots have been continuously upgraded intelligently, becoming the "nerve center" of the digital intelligent transformation of traditional manufacturing industry, which is expected to usher in large-scale applications in new energy vehicles, new retail and big health fields.

Facing the future, Titan Intelligence is building a general power platform for mobile robots, equipped with wireless charging system, power system, drive control system and background data management system, exploring software and hardware technologies, and establishing a development model of "energy products+data services".

Zou Jianjun believes that mobile robots must be one of the best carriers of AI applications, and connecting mobile robots with data services "chain" will be the development trend of the future industry.

In Zou Jianjun’s view, AGV charging product providers not only supply mobile robot parts, but also provide end customers with overall energy solutions from warehousing transformation to material docking and maintenance services. "This requires analyzing the density and quality of information collected by mobile robots from the data level to build a new ecosystem, which is also the underlying logic of our layout of this emerging business."

Evaluation of domestic self-developed chips in the new era Godson 3A4000

In recent two years, the domestic IC industry has been paid close attention to by people inside and outside the industry, and the momentum of domestic self-developed chips and domestic self-developed systems in the commercial field is growing. As a technology leader and supplier of domestic self-developed processors, Loongson Zhongke recently brought us a new generation of processor architecture products: Loongson 3A4000 processor.

Godson 3A4000

Introduction of Godson 3A4000

The Loongson 3A4000 processor uses 28nm technology and has four cores, which is consistent with the previous generation 3A3000. In terms of frequency, the Loongson 3A4000 processor is turbo-charged to 2.0GHz, while the 3A3000 processor is 1.5GHz, and the frequency is increased by 0.5GHz. In addition, the Loongson 3A4000 processor is upgraded to GS464V, which supports MIPS64 instruction set, and has expanded more than 1,000 instructions on the basis of only 500 instructions.

On the whole, compared with the previous generation 3A3000, the Loongson 3A4000 processor has not only greatly improved its performance, but also upgraded and optimized its security and encryption, built-in security modules and supported a variety of encryption and decryption algorithms.

Loongson 3A4000 mainframe sample

Because the Loongson 3A4000 processor is a domestic self-developed chip, facing the commercial field, it is not compatible with the mainstream American AMD and Intel platforms in the consumer market, so it needs to use the dedicated motherboard of the Loongson 7A2000 chipset to adapt to it. In addition, the Loongson 3A4000 processor is not compatible with the Windows system based on X86 architecture. The Loongson 3A4000 processor uses the upgraded GS464V architecture, which requires an adaptation system based on LINUX kernel.

This time, the system we used to test the Loongson 3A4000 processor is the UOS unified operating system (UOS is the system code, and this article will use the UOS system uniformly). Based on the LINUX kernel, the UOS system has been adapted to the Loongson 3A4000 processor.

UOS system

Although it is still in the testing stage, UOS system has great potential, which is a safe, easy-to-use and stable operating system product voluntarily initiated and developed by many domestic operating system core enterprises, which is of great significance. Besides Godson Zhongke, other domestic self-developed chip manufacturers will also adapt and support the UOS system, which means that the domestic hardware industry and software industry will be unified and integrated, which will greatly promote the development and progress of the domestic IC industry.

At present, except for the newly released 3A4000 processor, some other models of Loongson have been compatible with UOS system, fully adapting to Loongson desktop computers and servers. 

02 Loongson 3A4000 Test

This time, I had the opportunity to get the newly released Loongson 3A4000. We compared it with Loongson 3A3000.

Evaluation of domestic self-developed chips in the new era godson A4000
Loongson 3A4000 mainframe

Test platform:

The Loongson 3A4000 processor is a quad-core processor. The basic frequency of this CPU in our test host is 1.8GHz, which can be turbo-charged to 2.0GHz, with a memory of DDR4 2400 8G * 2, a memory of DDR3 128MB and a hard disk of 128G, and its bridge is 7A1000 bridge developed by Loongson.

Godson 3A4000 Host Configuration

Test items:

There are five items in our evaluation this time: WPS three-piece test, image and video opening speed and 7.Zip decompression comparison test, and finally Web page test and SPEC2006 test.

WPS three-piece test:

In the WPS three-piece test, we use more than 10MB documents, more than 20MB tables and more than 300MB PPT to test the opening speed of Loongson 3A4000 and Loongson 33000 processors.

Evaluation of domestic self-developed chips in the new era godson A4000
WPS three-piece test

There is no speed difference between the two processors when opening documents with a size of more than 10MB, both of which are within 1 second, but the author can still feel that the Loongson 3A4000 host is smoother and faster with the naked eye. However, the gap between the opening speed of forms above 20MB began to appear. Compared with 3A3000, the Godson 3A4000 improved by more than one second, and the gap in opening speed of PPT above 300MB increased by as much as three seconds. However, in fact, no matter whether using Godson 3A4000 or Godson 33000, daily work can be carried out smoothly without any bottleneck.

Picture Video Open Test:

In addition to office documents, let’s test the video opening speed and picture opening speed of the two processors.

Picture video opening speed

In these three tests, the Loongson 3A4000 processor still occupies an absolute advantage, which is faster than the Loongson 3A3000 processor. At the same time, it also tells us that there is no problem with the view and audio of these two processors, and both the view software, the video software and the OFFICE software linux have products corresponding to the Windows system, such as WPS corresponding to Office, so there is no need to worry about the problem of being unable to use and operate.

7.Zip decompression test:

7.Zip should be familiar to everyone. This is a very popular decompression software, which is often seen in Windows systems. One thing to note is that UOS did not pre-install 7.Zip. We used a notebook equipped with LOONGNIX processor, and the frequency was only 1.5GHz. The Loongnix mainframe was replaced by neokylin system.

After we open the terminal, we input the command LSCPU, and then we can start running after continuously inputting nuame-r and 7z a. The test results of Loongson 3A4000 and Loongson 3A3000 are as follows.

Evaluation of domestic self-developed chips in the new era godson A4000
Godson 3A3000 Godson 3A4000      

Compared with the 3,709 score of the Godson 3A3000, the running score of the Godson 3A 4000 at 1.5GHz is 5,470, which is about 47% higher, and the score is very impressive. 7.Zip is one of the most commonly used applications in daily life. Although it can’t fully reflect the processor performance, it can show the processor efficiency. Undoubtedly, the efficiency of the Godson 3A 4000 is greatly improved compared with that of the previous generation. If it is the Godson 3A4000 at 2.0GHz,

Principled Technologies WebXPRT 3 test:

Although the UOS system of Loongson 3A4000 platform has not supported much in software testing, the Web page testing is not restricted. The UOS system for web page testing that can be used in Windows system can also be used. We use the Principled Technologies WebXPRT 3 test, which can reflect the performance of all devices that support the Web.

The browser tested is a built-in browser in UOS system, based on the Chromium kernel, which is an open source core and is used by many browsers.

Godson 3A3000 Godson 3A4000    

This Web page tests that it contains six scenes based on HTML5 and JavaScript for mirroring daily tasks. In this test, the Loongson 3A4000 processor still achieved the performance crushing of the previous generation Loongson 3A3000, with a total score difference of 24 points.

In the six scenarios of JavaScript, the efficiency of each operation of Loongson 3A4000 processor has been greatly improved, including photo enhancement by about 63%, photo album arrangement by using artificial intelligence by about 74%, stock option pricing by about 59%, encrypted notes and OCR scanning by about 69%, sales charts by 69% and online work by 49%.

SPEC 2006 test

SPEC 2006 is a large-scale CPU performance test project, which can fully show the two most important parameters of CPU: fixed-point performance and floating-point performance, and has been recognized by everyone in the field of commercial CPU.

SPEC 2006 test

Evaluation of domestic self-developed chips in the new era godson A4000
SPEC 2006 test results

In the test, two processors, the Godson 3A4000 processor and the Godson 3A3000 processor, are compared. These two processors are both four cores. Whether it is the performance test of SPEC INT2006 fixed-point performance test, SPEC FP2006 floating-point performance test and STREAM(GB) memory bandwidth, the performance of the Godson 3A4000 processor has been greatly improved, almost doubling the effect. This performance can be achieved only by optimizing the architecture and increasing the price, which shows that the design and research and development of the Godson are amazing.

03 summary

At present, although the development of domestic chip industry is not as good as that of foreign semiconductor industry, especially foreign semiconductor manufacturers may invest tens of billions of dollars in chip research and development a year, while the domestic chip industry has limited funds, and the chip research and development starts later than foreign counterparts. There is indeed a gap as a whole. However, Loongson has been able to concentrate on research and development for 20 years on one architecture, and continuously iteratively upgrade the Loongson 3A processor chip. It has successively launched the Loongson 3A2000 processor, 3A3000 processor and 3A4000 processor just released at the end of the year, and kept its performance rising, which has fully demonstrated its R&D and design capabilities.

The performance of Godson 3A4000 processor is comparable to that of AMD’s Excavator architecture CPU, whether it is the underlying architecture or the physical design. Moreover, Godson 3A4000 processor can effectively prevent Meltdown and Spectre vulnerabilities, support encryption and decryption algorithms such as MD5, AES and SHA, and eliminate any risks in security.

The Loongson 3A4000 processor adopts 28nm process, and there is still a lot of room for upgrading and optimization. Under the same 28nm process, the CPU performance of the Loongson 3A4000 processor is improved by 6 times compared with that of the first-generation Loongson 3A1000 processor with the same process. It is reported that the next-generation Loongson 3A5000 processor will use 12nm process next year, and the CPU frequency can be increased to 3.0GHz, which is full of stamina.

Ordinary users may have questions, why do you want to launch domestic self-developed CPU chips so vigorously, and it is not good to introduce it abroad? It may be practical in the short term, but it must not be a long-term solution. The core technology is not in our own hands and will inevitably be subject to others. In the field of domestic CPU, what we need to do now is not to catch up blindly, but to avoid being useless, that is, what we need to solve now is the problem of 0 and 1. It is believed that Godson, which has always insisted on independent design and has the ability to realize all independent designs, can enter the civil market in the near future.
