Diaphragm materials are common in our life, such as explosion-proof film on automobile glass and protective film on mobile phone panel. What many people don’t know is that there is also a diaphragm in our mobile phone battery, which is used to prevent the battery from short circuit and transmit ions at the same time. After years of research, researchers of China University of Science and Technology designed a new type of ion conducting membrane. This ionic membrane is expected to be widely used in energy conversion, large-scale energy storage and distributed power generation. The research results were published in the international academic journal Nature on April 26th, Beijing time.

△ Researchers show the new domestic ionic membrane.

　　Ion-exchange membrane is the key component of electrochemical devices or equipment such as flow battery and fuel cell. It should not only prevent short circuit, but also ensure the efficient passage of ions during charging and discharging, and reduce the loss. However, traditional ion-exchange membrane is prone to swelling and deformation after absorbing water, and its structure is loose, especially after being used for a long time, which may lead to structural aging and performance degradation. This kind of new ionic membrane developed by researchers of China University of Science and Technology has solved the problem that ions can’t have both conductivity and selectivity in materials, and the ion transmission is faster, and the near frictionless conduction is realized in the membrane. The charging and discharging current density of the flow battery assembled with this membrane can reach 500 mA per square centimeter, which is stronger than the traditional ionic membrane, less prone to aging, and will not swell due to water absorption.

　　It is understood that for many years, efficient storage and utilization of new energy sources such as solar energy and wind energy has been an important research and development topic for Chinese researchers. The advent of this domestic ionic membrane will break the technical monopoly of similar products abroad for many years, greatly improve the efficiency of energy storage equipment such as flow batteries, and is expected to be widely used in the energy storage field of new energy sources such as solar energy and wind energy in China. At present, researchers are stepping up the mass production of this type of ionic membrane.

　　Professor Xu Tongwen of China University of Science and Technology introduced that we can combine this new flow battery energy storage technology with our power grid for household electricity and industrial production. We can also store the electricity generated by solar energy and solar panels and build a power station to charge cars. In this way, we can save energy and protect the environment, and promote our country to achieve the goal of "double carbon". (CCTV reporter Chu Erjia Wang Shuai)

The tank brand officially released the "off-road+new energy" technical route and the off-road super hybrid architecture. At the same time, two production hybrid models, the tank 300 HEV and the tank 500 PHEV, were unveiled. According to reports, the next tank 700 and 800 models will also launch hybrid models. In the niche hard-core SUV sequence in the era of high oil prices, tanks once again took the lead.

Tank brand This year’s Chengdu Auto Show released the technical route of "off-road+new energy" and the off-road super hybrid architecture, and promoted the new energy off-road as an emerging niche category to enter the public eye. As Liu Yanzhao, CEO of tank brand, said at the press conference, "New energy off-road has become a prairie fire. The new energy utilization of off-road vehicles needs to be based on off-road, and the application of electricity is auxiliary, rather than putting the cart before the horse. "

Therefore, the fundamental of tanks is off-road capability. At this point, the team of the tank brand is deeply aware of where the trigger point of the technical route is. From fuel and hybrid to "electric tank", the tank brand is "one key and three connections".

The off-road super hybrid architecture integrates the core advantages of engine and motor parallel dual direct drive, TOD+ differential lock top mechanical four-wheel drive system, intelligent SOC energy management, etc. It is compatible with outdoor off-road and urban travel, and realizes the full scene coverage of low, medium and heavy off-road.

Based on the off-road super hybrid architecture, the tank unveiled two production hybrid models-the tank 300 HEV and the tank 500 PHEV.

The 300 HEV version of the tank is equipped with a 2.0T Miller cycle engine and a 9HAT transmission, with a maximum power of 224kW and a maximum torque of 640Nm. When driving in the city, the motor is directly involved, and the acceleration of 100 kilometers is within 9s; In the process of crossing driving, the motor can also provide extra power and longer battery life. At the same time, the fuel consumption in the congestion process is greatly reduced by the addition of the motor. In terms of energy saving, the comprehensive fuel consumption per 100 kilometers is as low as 10L under WLTC working conditions, and the fuel consumption can be as low as 9L under urban working conditions combined with an efficient energy recovery system.

The 500 PHEV plug-in hybrid version of the tank is equipped with a battery with an electric capacity of 19.94kWh. With the 2.0T+9HAT powertrain, the maximum comprehensive power is 300kW, the maximum comprehensive torque is 750Nm, and the acceleration time of 0-100km/h is only 6.6 seconds. It can be powered by oil and electricity, and it is strong, quiet and smooth.

The high-efficiency hybrid system can achieve the comprehensive fuel consumption of WLTC of 4.4L/100km and the comprehensive endurance of 736km at full charge. At the same time, the battery system supports 0.5-hour fast charge and 3-hour slow charge, and has 3.3kW external discharge power.

This year, two models, the tank 300 HEV and the tank 500 PHEV plug-in hybrid version, will be pre-sold globally. In the future, 3.0T V6 PHEV products will also be installed on high-end models such as Tank 700 and Tank 800, and will be introduced to the market one after another.

Three drivers’ views:

The data shows that as of July this year, the total sales volume of tank models has exceeded 150,000, and the market share of the hard-core off-road market has reached 56%. As of August this year, the distribution of tank brand channels has covered more than 100 networks nationwide, relying on experience centers, supermarkets, city exhibition halls and delivery centers. It took less than a year for a tank to jump from a model to a brand, and it entered the market with the attribute of online celebrity, but now it needs strong systematic ability to remain competitive.

From 1931 to 1934, Henan University spent three years and more than 210,000 yuan to build a palace-style auditorium.

In the process of construction, builders not only fully consider its safety and firmness, but also take into account its applicability and beauty. Members of the Architectural Committee of the Auditorium and accountants are all "unpaid". With hard work and selfless dedication, they left a permanent public building and an eternal spiritual wealth.

Early Henan University Auditorium

In 1912, on the former site of Henan Gongyuan, Henan Preparatory School for Studying in Europe and America was established. At the beginning, most of the school buildings used in the school were old houses in Gongyuan. In 1919, when Li Jingzhai was the principal, the school built Building 6. The building has a large area, so a lecture hall, the so-called auditorium, can accommodate three or four hundred people. Any assembly will be held here.

Building 6 has long been used as a lecture hall.

In March 1923, the pre-school was renamed Zhongzhou University, "the site of the headquarters is near Caomen in the south, the iron tower in the north, the city wall in the east and the Huiji River in the west." With the support of President Zhang Honglie, Li Jingzhai, director of school affairs, made an overall plan for the campus. From pre-school to university, the number of students has gradually increased, and although the lecture hall is crowded, it can barely be used. In August 1925, Li Dazhao gave a speech here entitled "The History of British Imperialism’s Invasion of China".

Zhongzhou University Planning Map

In 1927, Zhongzhou University was renamed as Henan Sun Yat-sen University after it merged with Henan Public Law School and Henan Provincial Agricultural College. As an auditorium, the lecture hall is still an important place for teachers and students to gather. In the winter of 1929, Fu Sinian gave a lecture in the lecture hall, talking about the development of archaeology and the excavation of Yin ruins. However, the number of students has increased to more than 900, and the lecture hall in Building 6 can no longer accommodate them.

It is extremely necessary to build an auditorium for teachers and students to gather, but it is difficult to raise funds for the construction.

As early as August 1922, under the impetus of Feng Yuxiang and Governor Zhang Fengtai, Henan Province formed a system of using deed tax as education funds and using it independently, and set up a special agency to distribute the education funds in the province. However, wars are frequent, the provincial fiscal revenue is uncertain, and the school allocation quota is difficult to guarantee. For example, in 1927, the fabricated budget was 300,000 yuan, and the school actually received 129,700 yuan; In 1928, the fabricated budget was 255,000 yuan, and the actual income was 227,000 yuan.

It is not easy to maintain school expenses, let alone build an auditorium. The school applied to the provincial government for funds to build the auditorium, but failed to do so. In desperation, the school built a shed as an auditorium and meeting place, which was not only unsightly in appearance, but also could not be used often in winter and summer because of the weather.

The school magazine of Henan University published on September 21st, 1933.

In 1930, the Central Plains War broke out. After defeating Feng Yuxiang, Chiang Kai-shek appointed his lineal Liu Zhi as the chairman of Henan Province. In September, Henan Sun Yat-sen University was renamed as the provincial Henan University. When President Zhang Zhonglu announced the five-year development plan to teachers and students, he was still in the school shed. Soon, Zhang Zhonglu announced his resignation. Zhao Xinwu acted as the principal for only two months, and Li Jingzhai, the provincial director of education, served as the principal for only four months. Principals change frequently, and their tenure is not long, so they have no time to take care of the construction of the auditorium.

Time and cost of building the auditorium

In May 1931, the provincial government appointed Xu Xinwu as the principal, and the construction of the auditorium ushered in a turning point.

President Xu Xinwu

Xu Xinwu studied in the United States in his early years and obtained a master’s degree in hydraulic engineering. After taking office, together with Li Jingzhai, he made adjustments and supplements to the campus planning of Heda University, and put forward suggestions for building the auditorium. At the same time, under the planning of President Xu Xinwu and Dean of Science College Zhao Xinwu, the school added a department of civil engineering, which was approved by the provincial government in June.

At that time, the Department of Civil Engineering was affiliated to the Faculty of Science, with Qu Wenlin as the dean. Qu Wenlin graduated from the Department of Civil Engineering of National Beiyang University (now Tianjin University) in 1921, was appointed as a teacher of Henan Institute of Surveying and Mapping of Water Conservancy Engineering, and took a part-time course in the School of Science of Henan University. The establishment of the Department of Civil Engineering not only expanded the disciplines and specialties of the school, but also provided technical support and talent guarantee for the building auditorium.

The construction of the auditorium was supported by teachers and students, and also by the provincial government. Although Liu Zhi was born in the military, he attached great importance to the revitalization of education during his administration in Henan, especially supported the construction of the auditorium. Later, in My Memories, he wrote: "To raise funds, build the auditorium of Henan University, expand and repair the school buildings of primary and secondary schools, and build the magnificent North China Stadium, in order to seek the initial measures for the development of education in Henan and arouse the joint efforts of local people."

In order to ensure the smooth progress of the project, the school hired Zhang Boying (namely zhangfang, then director of the provincial construction department), Li Jingzhai (then director of the provincial education department), Du Xiu monk (namely Joe Doo, then director of the education fund and production management department) and Qu Wenlin to form the Auditorium Construction Committee, among which Li Jingzhai, Du Xiu monk and Qu Wenlin served as the standing Committee members, who were responsible for design, economy and engineering. At the same time, Yan Shaozhang was hired to be responsible for drawing and project management. Yan Shaozhang participated in the topographic survey of North China Stadium, and was then an engineering professor at Henan University. (See "General Report of the 16th North China Games" published by Shanghai Dadong Bookstore in 1932, p. 101.) As for the positions such as accounting and general affairs, some school staff are concurrently employed.

Profile of auditorium

After intense and detailed planning, on November 20, 1931, the auditorium broke ground. On April 10, 1932, the school held a groundbreaking ceremony. The original construction period was one and a half years, but the project lasted until the winter of 1934. Due to weather changes, uneven materials and other reasons, the project has been shut down for 11 months, so the actual construction period is two years. In more than 750 days, the members and part-time staff of the Construction Committee were "not given jobs", which not only ensured the construction progress and project quality, but also saved a lot of expenses.

Before construction, the construction cost budget is about 140,000 yuan, and the equipment cost budget is about 30,000 yuan. With the consent of Liu Zhi, the Finance Department allocated 150,000 yuan for construction and 24,296 yuan for equipment. In addition, Zhongyuan Company donated 10,000 yuan. These payments, together with the interest generated one after another, total 185,143.18 yuan.

The expenditure on the construction of the auditorium consists of two parts: construction cost and equipment cost. The construction cost is more than 190,000 yuan, and it costs 145,998.817 yuan to buy wood, bricks, limestone, steel and miscellaneous parts. The total number of employees is 73,520, including 21,920 carpenters, 22,600 masons, 25,500 coolies and 3,490 handymen, with a total cost of 45,250.573 yuan. The expenses including steel chairs, electric lights, heating and other materials are called equipment expenses. When the auditorium was completed, only steel chairs were installed, and other equipment was not added, including 12,894.8 yuan for steel chairs, 5,827.8 yuan for transportation and 109.22 yuan for travel remittance. After adding up the construction cost and equipment cost, the actual expenditure reached 210,081.21 yuan.

Qu Wenlin made a detailed analysis of the construction time and expenses in the report. In his view, the reinforcement of foundation engineering, the purchase of steel frames from Britain, the change from wooden floors to reinforced concrete floors, the reinforcement of walls with steel bars and concrete, and the extension of construction period are the main reasons for exceeding the original budget.

The auditorium is sturdy and applicable, beautiful and cheap.

The engineering design of the auditorium is based on the safest standard. In order to ensure the safety of buildings, all materials used are assumed to have the largest external force and the smallest resistance. Although the cost of materials has increased, as a permanent public building, the safety and firmness of the auditorium have been greatly improved. For example, when building the foundation, the designer thought that the terrain of the auditorium was similar to that of Building No.7, but when he dug six feet, he found quicksand and serious water seepage. Designers and constructors use concrete as the lower foundation, and then arrange bricks closely, add mortar, and the foundation brick soil is made of lime, and the size is relaxed, and the load per square foot is calculated according to the worst foundation to ensure safety.

For another example, the auditorium was originally planned to use wooden floors, but for the sake of fire safety, all of them were replaced with steel bars and concrete. The south wall of the venue cannot be thickened due to the bearing capacity of the foundation. In order to ensure the safety, a reinforced concrete beam is added, extending from the east end to the west end and along the east wall to the north, with a total length of 160 feet to support the floor pressure, and 8 reinforced concrete columns are added to support the steel beam.

The interior window area of the auditorium accounts for one-fifth of the venue area, so the light is sufficient. The air capacity in the venue is 400,000 cubic feet, with an average of 160 cubic feet per person. The air is very smooth. In addition, the echo in the auditorium is very small, so you can hear it clearly at the end. Upstairs and downstairs, more than 2600 people can sit in the middle space. The podium, 60 feet wide and 40 feet deep, can hold meetings and plays, and can accommodate more than 200 people. In addition, there are 8 rooms upstairs and downstairs, which can be used as lounge, office, storage room and classroom, each holding 60 people. There are walkways around the venue, upstairs and downstairs for easy access.

Overlooking the auditorium

As the main building of the school at that time, the exterior of the auditorium was in the form of palace architecture, with upper plates in the corners, covered tiles and painted colors similar to those of the palace, while the interior was in the form of modern architectural techniques, with a view to being applicable. From all angles, the auditorium is magnificent and magnificent. Considering the construction cost, the auditorium can be regarded as inexpensive. Qu Wenlin said: "The cost of the Auditorium of Nanjing Central University and the Auditorium of Tsinghua University is nearly 200,000. Although the design of materials and materials are different, our auditoriums are quite unique in terms of beautiful area and solid capacity."

It is reported that Kangzhou Medicine was established in Jiangning High-tech Zone in October 2017. The intimate rent and decoration subsidies in the park, as well as the policy of scientific and technological talents, helped enterprises to save a lot of expenses in the growth stage and attracted biomedical talents with international standards to settle in. At that time, China’s MAH (drug listing permit holder) system had just been piloted for more than a year, and Kangzhou Medicine became the first "listing permit holder under the MAH system" enterprise in the province.

It is understood that before the implementation of the MAH system, only pharmaceutical companies with production capacity are eligible to apply for drug marketing licenses. After implementation, R&D institutions can also apply for drug marketing licenses, and hold their own drug numbers and entrust relevant pharmaceutical companies to produce and sell.

With the help and support of Jiangning High-tech Zone, in 2018, taking advantage of the "east wind" of the policy, three products, namely, Kangzhou Pharmaceutical Atosiban Acetate Injection, Terlipressin for Injection and Carbetocin Injection, were initiated for project research. Among them, Atosiban Acetate Injection, which is used to protect the fetus, advanced the fastest, and was first approved for listing in March 2021. In February and April 2023, it was used to treat complications of liver cirrhosis, respectively.

Ganarik acetate injection listed by Kangzhou Medicine this time is a generic drug of four categories, and it is the second domestic one approved for listing, which is regarded as having passed the consistency evaluation. The drug is a down-regulating drug in the field of assisted reproduction, belonging to gonadotropin-releasing hormone antagonist. It is used in women receiving controlled ovarian stimulation scheme of assisted reproduction technology to prevent premature luteinizing hormone peak. Kangzhou Pharmaceutical Ganarik Acetate Injection is prepared by a new process, which can replace imported products, provide patients with a higher choice of quality and price ratio, and reduce the economic burden. At present, Kangzhou Medicine has established a product line consisting of dozens of products, covering reproduction, digestion, metabolism and other fields, and many products are to be declared.

In the field of biomedicine, Jiangning has more than 1,300 enterprises of various types, covering key areas such as research and development and production of innovative drugs, cell and gene therapy, CRO/CDMO and new medical devices, and has built an industrial innovation system for biomedicine and new medical devices. Biomedical characteristic industrial base was rated as the characteristic industrial base of national torch plan.

At present, Jiangning District is accelerating the establishment and improvement of the "R&D+Clinical+Production+Application" bio-pharmaceutical industry life-cycle ecosystem, and constantly cultivating a number of new enterprises and new products in innovative drugs, high-end medical devices, immune drugs and other sub-areas, and striving to make the scale of bio-pharmaceutical industry account for more than 1/4 in the city.

CCTV News:From December 12th, the railway department will start to sell train tickets for Spring Festival travel rush in 2020. Passengers can book tickets for the first day of Spring Festival travel rush through the Internet and telephone. As the pre-sale period of tickets at the ticket window and sales outlets of the railway station is 28 days, tickets for the first day of Spring Festival travel rush will be sold at the window on December 14th. The reporter learned from Guangzhou Railway Station that during Spring Festival travel rush this year, Guangzhou Railway Station is expected to send 3.17 million passengers.

Spring Festival travel rush begins on January 10th, 2020 and ends on February 18th, totaling 40 days. During the Spring Festival travel rush in 2020, Guangzhou Station is expected to send 3.17 million passengers, which is basically the same as in previous years. It is estimated that the peak period of passenger delivery will be concentrated from January 19th to 21st, and the peak day will reach about 140,000 passengers.

Huang Ni, deputy stationmaster of Guangzhou Railway Station:This year’s passenger flow will come earlier, and the student flow and the work flow will be carried out at the same time, and the passenger flow will be in the direction of Chengdu, Chongqing and Quxian.canIt’s a little bigger.

In order to cope with the peak passenger flow in Spring Festival travel rush, Guangzhou Railway Station has added passenger trains from Baoji, Liangping and Chongqing in the direct direction of Spring Festival travel rush this year, and set the ticket collection office in front of the entrance, so as to reduce the time for passengers to take tickets around and avoid the crowded ticket office.

Huang Ni, deputy stationmaster of Guangzhou Railway Station:In order to cope with the peak passenger flow, a large number of southwest-oriented cars were added to the station, 50 ticket gates were added at the entrance, 30 ticket gates were added at the main entrance, and 15 and 12 ticket gates were added on the east and west sides. In August this year, the station reform project was carried out, and the waiting area was expanded on the basis of last year, so the waiting environment will be more suitable.

In addition, during the period of Spring Festival travel rush, some lines in Guangzhou South Railway Station can use electronic tickets to enter the station. After booking tickets for specific lines online through the official channel of 12306, passengers will generate a dynamic QR code, which can be directly scanned to enter the station. At the same time, the railway department also reminds passengers that since the pre-sale period of ticket purchase at the ticket window and sales point of the railway station is 28 days, the time for purchasing the first day ticket of Spring Festival travel rush at the window is December 14th, so the majority of passengers can purchase it as needed.

　　◎ reporter Zhang mengran

　　Have you searched the Internet for "What hurts me? Is there something wrong with me?"? The answer may not be satisfactory. However, with the emergence of large-scale natural language models (LLM) such as ChatGPT, people began to try to use it to answer medical questions or medical knowledge.

　　However, is it reliable?

　　As far as it is concerned, the answer given by artificial intelligence (AI) is accurate. However, James Davenport, a professor in university of bath, pointed out the difference between medical questions and actual medical practice. He believed that "medical practice is not just about answering medical questions. If we just answer medical questions, we don’t need to teach hospitals, and doctors don’t need to receive years of training after academic courses."

　　In view of all kinds of doubts, in a recent paper published by Nature, the world’s top artificial intelligence experts showed a benchmark to evaluate how well large-scale natural language models can solve people’s medical problems.

　　The existing model is not perfect.

　　The latest assessment comes from Google Research and Deep Thinking. Experts believe that the artificial intelligence model has many potentials in the medical field, including knowledge retrieval and supporting clinical decision-making. However, the existing model is not perfect, for example, it may fabricate convincing medical error information, or include prejudice to aggravate health inequality. Therefore, it is necessary to evaluate their clinical knowledge.

　　Relevant assessments have not been without before. However, in the past, it usually relied on automated evaluation of limited benchmarks, such as individual medical test scores. This is translated into the real world, and both reliability and value are lacking.

　　Moreover, when people turn to the Internet to obtain medical information, they will encounter "information overload" and then choose the worst one from 10 possible diagnoses, thus bearing a lot of unnecessary pressure.

　　The research team hopes that the language model can provide short expert opinions, be unbiased, indicate its citation source, and reasonably express uncertainty.

　　What is the LLM performance of 540 billion parameters?

　　In order to evaluate the ability of LLM to encode clinical knowledge, Xie Kufei Aziz, an expert from Google Research Institute, and his colleagues discussed their ability to answer medical questions. The team put forward a benchmark called "MultiMedQA QA": it combines six existing question-answering data sets covering professional medical care, research and consumer inquiries and "HealthSearch QA" & mdash; — This is a new data set, which contains 3173 medical questions searched online.

　　The team then evaluated PaLM (a 540 billion parameter LLM) and its variant Flan-PaLM. They found that Flan-PaLM reached the most advanced level in some data sets. Flan-PaLM surpassed the most advanced LLM by 17% in the MedQA data set integrating the questions of American medical license examination.

　　However, although Flan-PaLM scored well in multiple-choice questions, further evaluation shows that it has a gap in answering consumers’ medical questions.

　　LLM of specialized medicine is encouraging.

　　In order to solve this problem, artificial intelligence experts use a method called design instruction fine-tuning to further debug Flan-PaLM to adapt to the medical field. At the same time, the researcher introduced an LLM— — Med-PaLM。

　　Fine-tuning design instructions is an effective way to make general LLM suitable for new professional fields. The resulting model Med-PaLM is encouraging in the trial evaluation. For example, Flan-PaLM scored by a group of doctors is only 61.9% consistent with the scientific consensus, and Med-PaLM scored 92.6%, which is equivalent to the answers made by doctors (92.9%). Similarly, 29.7% of Flan-PaLM’s answers were rated as likely to lead to harmful results, and only 5.8% of Med-PaLM’s answers were equivalent to those of doctors (6.5%).

　　The research team mentioned that although the results are promising, it is necessary to make further evaluation, especially in terms of safety, fairness and prejudice.

　　In other words, there are still many limitations to overcome before the clinical application of LLM is feasible.

According to Indonesia’s latest Trade Minister Order No.31 of 2023,Social media will no longer be used as a platform for commodity sales, but only as a channel for the marketing or promotion of goods and services.When social media can not be used as a sales platform to complete closed-loop transactions, how to find out?A new set of closed-loop logic of diversion+transformation?

First, the huge social e-commerce dividend of Indonesian e-commerce

There are 212.9 million Internet users in Indonesia, with an Internet penetration rate of 77.0%.

Indonesia has 167 million social media users, equivalent to 60.4% of the total population.

Indonesian netizens spend more than 3 hours on social media through various devices every day on average.

Data as of January 2023, source Digital2023:Indonesia

Indonesia’s demographic Internet dividend seems to be the same as that in China ten years ago, and the huge user base provides space for the development of social media. After the launch of the social media+store model, social e-commerce quickly penetrated.

Indonesian local merchant Fefenia sells woven handbags through social e-commerce, and 90% of its business centers are placed on a single short video social channel. However, due to the newly issued rules, the closed loop of his social media connection transaction has broken, and he needs to find a new "shelf" for his business in a short time.

A single channel may temporarily boost the vitality, but multiple sales channels and multiple flow channels can lengthen the vitality of the whole business operation.

Second, SHOPLINE SC builds a traffic runway for social e-commerce

Where is the "traffic", where is the business? This is the initial intention of Indonesian e-commerce to rely heavily on social media; A strategy that can lead the "flow" to the closed-loop trading is a good strategy.

In view of this, SHOPLINE Social Commerce allows users to undertake e-commerce links accurately, reliably and automatically by building a traffic runway. Merchants only need to configure keywords, and the system can automatically capture all comments and classify products into orders for customers to choose.

Take the live broadcast of SHOPLINE SC X Facebook as an example: Step 1: The merchant assigns keywords to the products and adds them to the live broadcast room; Step 2: During the live broadcast, broadcast the keywords of the products, such as "C3", and guide users to leave messages in the comment area.

Step 3: Customers reply to product keywords in the comments and get automatically generated links to participate in the purchase.

Considering that merchants may set up live broadcasts from multiple platforms, all Livestream will be collected in the SHOPLINE backstage live broadcast dashboard, which can be realized whether viewing real-time orders, replying to messages, tracking inventory or reminding checkout.

SHOPLINE’s social e-commerce strategy helps sellers accumulate global user assets and realize the continuous growth of GMV by dredging traffic conversion.

Third, to achieve the ultimate localization, they chose SHOPLINE.

SHOPLINE Social Commerce is a leading social e-commerce service platform in Southeast Asia, which has provided services to tens of thousands of merchants, with weekly orders reaching 100,000+and GMV of 10 million dollars, mainly generated by live broadcast for merchants in Southeast Asia.

SHOPLINE insists on localization services in the local market, and more and more brand businesses accumulate potential energy and increase the speed through cooperation with SHOPLINE in Indonesia.

Fourth, the full link scheme of independent stations from station construction to performance end-to-end
