Editor’s lead: In cross-border e-commerce OMS system, inventory is also very important, and reasonable inventory design is helpful to ensure the normal operation of OMS outbound. So how to deal with the locking and releasing of inventory? In OMS, how should the change of online inventory be added into the scope of design consideration? Let’s take a look at the author’s summary.

OMS issue documents will have several key nodes, and the corresponding logic needs to be completed at different nodes to ensure the subsequent normal circulation of documents.

In cross-border e-commerce OMS, the key points are: logistics ordering, freezing of withholding funds, locking, release and deduction of inventory, etc. An article has been written before logistics ordering.This time, let’s talk about locking, releasing and deducting inventory..

For cross-border e-commerce overseas warehouse OMS, there are generally several scenarios for inventory locking:

1. Lock the inventory when it is created;
2. Place an order for logistics, and lock the inventory when obtaining the logistics list;
3. Lock the inventory when submitting the outbound order to WMS.

There will be different business scenarios for different customers, so the inventory locking is generally different. These three scenarios are not optional, but all three, and they should be flexibly combined.

If some customers are strict and want to occupy some inventory when creating the outbound order, they will lock the inventory after creating it.

Some customers have no special requirements for inventory locking, so the normal situation should be to lock the inventory when they get the logistics list.

There are also some customers who may upload their own logistics sheets or do not require logistics sheets, so they can set to lock the inventory when submitting the outbound order to WMS.

It is suggested that the timing of inventory locking should be made into a policy rule. Every time a different customer is introduced, the corresponding rule can be configured. If there is no configuration rule, the default node will be adopted, which can flexibly take into account the needs of different customers.

With the lock of inventory, there will naturally be the release of inventory. In fact, the locking and releasing of inventory can be divided into two groups. The first group is locking and releasing, and the second group is locking and deducting.

The inventory is locked, which means that the outbound order occupies this part of the inventory, and the system needs to mark it as locked to prevent it from being preempted by other outbound orders. So if I cancel the outbound order, I need to release the lock of this block, so the corresponding release of inventory lock actually refers to the scene where the outbound order is cancelled or intercepted.

If this outbound order is completed, the corresponding inventory needs to be deducted. At this time, the locked part will be converted into the deducted part, which is equivalent to emptying the locked quantity first, then increasing the deducted quantity (inserting the inventory flow), and finally the available inventory will remain unchanged.

Here we need to pay special attention to two issues, one is the timing of release, and the other is the quantity of release.

Regarding the timing of release, for the cancellation or interception of the outbound order, when the cancellation or interception is successful, then release it. For the normal issue of outbound order, we need to pay attention to one question:How to define outbound?

On the surface, the goods leave the warehouse, which is called outbound. However, in the actual business scenario, it may take a day or two for the goods to be picked up by the logistics provider after picking and packaging, and the outbound node will be late at this time. It may also be taken away by the logistics provider, but there is no rigorous handover action, resulting in some outbound documents not marked as outbound, so they have been in a state of waiting for outbound, and inventory cannot be deducted.

How WMS defines outbound will affect when OMS deducts inventory, so this piece needs to be combined with business to explore an optimal solution. If the "delivery" is too early, the time period for customers to intercept the delivery will be very short, and the actual goods will not go out, but they cannot intercept the delivery, which will increase losses in vain; If "outbound" is too late, it is possible that some outbound documents will be marked as overtime outbound, which will affect the rating of platform stores.

Regarding the quantity released, for overseas warehouses of cross-border e-commerce, there is basically no so-called partial outbound or multi-batch outbound, and most businesses are issued in a single order and completed at one time. So don’t expand here, just make a reminder.If the issue quantity does differ, it is necessary to ensure that the actual available inventory quantity is accurate in consideration of the locked quantity, and the difference can be adjusted by some exception handling methods.

In-transit inventory is a link that is easily overlooked by everyone. Sometimes, I even feel that this data is useless, and then I forget that there is such a thing when designing some logic.

I’ve been looking for information about in-transit inventory on the internet for a long time, and it turns out that many articles seem to be shallow or complicated, which makes it particularly uncomfortable to understand.

Here, I would like to sum up how the in-transit inventory in overseas warehouses of cross-border e-commerce is generally used within my personal knowledge. It is only my personal opinion, so please pay attention to dialectical treatment.

If you want to simply understand the in-transit inventory, it is enough to analyze it directly from the two most common ways to produce the in-transit inventory. They are:

1. Allocation is on the way;
2. Purchasing is on the way.

Transfer in transit is the in-transit inventory generated in the process of transferring from warehouse A to warehouse B. For warehouse a, the goods have left warehouse a, so the inventory of warehouse a has been deducted; For warehouse B, the goods are on the way to transport, but they have not been put into storage yet, so they cannot be counted as available inventory, but only in transit.

There are many similarities between purchase in transit and transfer in transit, both of which are sent from one place to another. It’s just that the purchase involves some settlement problems with external suppliers, so it’s a little troublesome. For the warehouse that is about to receive the purchased goods, the goods are still on the road and have not been put on the shelves, so it can’t be counted as available inventory, but only in transit.

In-transit inventory can estimate the inventory in the future for a period of time to guide the sales decision; In-transit inventory will also occupy the cost of capital, so the financial department will pay attention to and attach importance to this piece of data.

For cross-border areas, because the process of stocking goods to overseas warehouses (the first journey) takes a long time, the controllability of in-transit inventory is particularly important for sellers. In addition to counting the actual available inventory of each overseas warehouse, we also need to pay attention to this part of the inventory in the process of stocking, and make an inventory plan in time.

For OMS, the definition of in-transit inventory generally refers toAfter the receipt document is submitted to the warehouse, but before the warehouse receives the goods, the total inventory in this period of time..

If the warehouse is actually put on the shelves, the in-transit inventory will be converted into available inventory. If the actual receipt of goods in the warehouse is less than the forecast quantity, but the receipt document is forced to end, then the inventory in transit needs to be reduced accordingly. Because the receipt document has been closed, the in-transit inventory should be converted into available inventory according to the actual quantity on the shelves, and the extra part should be invalidated and released because it can no longer be put on the shelves.

Schematic diagram of inventory change in transit

For OMS, it is important to pay attention to the number of SKUs whose receipt status is submitted between shelves. This part needs to dynamically adjust the number of in-transit inventory according to the actual number of shelves fed back by the warehouse, and finally pay special attention to some nodes of differential receipt and differential shelves.

In OMS outbound, the logistics ordering and rule engine are the most complicated, and the locking and releasing of inventory is the most basic requirement, so I didn’t write anything too deep, just briefly summarized and reviewed the past project experience.

In fact, the logic of locking and releasing the inventory is the same as that of withholding fees from the issue document. After locking the inventory, the corresponding fees will be frozen, and after releasing the inventory, the frozen fees will be released or deducted accordingly. It’s just that the content involved in billing is partial and the content is miscellaneous, so I won’t talk much here.

And the inventory on the way is because there are really too few online materials, so I made a fool of myself again and output some of my own shallow views and opinions.

I hope this article can help you. See you next time!

　　This "homework together" software has an option of "contributing to class learning beans", and parents can buy "learning beans" to contribute to class teaching. Usually, 10 yuan can buy more than 200 beans. Some parents are worried that this will lead to comparison psychology. At present, the software company said that it has closed the function of parents buying "learning beans".

　　Recently, Fangcao Primary School in High-tech Zone recommended downloading a software called "Working Together" to all students, through which students can finish their homework and get a reward called "Learning Bean" — — "Xuedou" can be exchanged for prizes such as stationery. However, apart from whether it affects children’s eyesight and encourages them to indulge in game disputes, a bigger controversy is passed on among parents: parents can spend money to buy "learning beans" and donate them to classes. Some parents are worried that this will lead to comparison psychology.

　　Parents can buy more than 200 "learning beans" in 10 yuan.

　　At about three o’clock on the afternoon of October 27th, parents who picked up students had gathered at the entrance of Fangcao Primary School in Chengdu High-tech Zone. Parents gathered in twos and threes to discuss the software "Working Together". "The school held an emergency meeting and has suspended the use of this software." A student’s parents told reporters that part of their children’s English and math homework is usually done in this software.

　　By searching the download address of the software, the software of "Working Together" is divided into teacher’s end, student’s end and parent’s end. The teacher arranges homework on the software, and the students finish homework on it. After the homework is submitted, the parents can see the completion and score of the whole homework.

　　"All three parties can get involved." A student’s parents said that at first, the teacher sent a link in the group, and then everyone downloaded it. Students mainly used their mobile phones or ipad to complete their homework.

　　According to students’ parents, students will be rewarded with "learning beans" issued by the system after completing their homework. Of course, teachers can also issue learning beans to reward students with good completion. According to the number of "learning beans", students can rank on the list of academic tyrants.

　　However, you can see in the parents’ client that there is an option of "contributing to class learning beans", where parents can buy "learning beans" and then contribute them to class teaching. Under normal circumstances, 10 yuan can buy more than 200 learning beans.

　　Some parents are worried that it will cause blind comparison.

　　"Parents can spend money to send learning beans to their teachers. Will it develop into ‘ Thanks to Xiaoming’s father for sending the rocket to the teacher ’ ！” A parent said this anonymously on the Internet. During the on-site interview, some parents also said that the teacher can see which parent donated "learning beans to the class", and it is not excluded that some parents will gain the teacher’s favor in this way, which will lead to blind comparison.

　　Yesterday, the reporter contacted the software customer service, and asked if the donated beans could be given to their children. The other party said that these beans were deposited in the teacher’s account and distributed by the teacher. "Of course, you can communicate with the teacher." The customer service added.

　　According to the relevant person in charge of the software company, at the beginning, teachers distributed learning beans all provided by the system, but the amount was limited. "Some parents put forward hope contributions ‘ Xuedou ’ Teach the class. " She said that this is why the software is equipped with the option of "contributing to the class to learn beans". However, "contributing to the class to learn beans" is a "black box" and parents cannot see whether they have bought this kind of "learning beans".

　　Software company: At present, the function of buying "learning beans" has been turned off.

　　Yesterday, the reporter came to the school and wanted to know about it. When he contacted the academic affairs office of the school twice, the relevant staff said that they didn’t know about it.

　　On the official WeChat of the school, the school replied to the parents. The school said that the school held an emergency meeting overnight, convened relevant teachers, parents’ representatives, and the person in charge and staff of "Work Together Information Technology Co., Ltd.", "launched an investigation".

　　According to the official WeChat reply, Miss Li, an English teacher at school, came across this APP software during a teaching and research activity, and thought that the platform was "flexible, interesting and interactive, especially it can timely feedback students’ learning effects, guide students to correct themselves and other functions, and it is free", so students are recommended to download this software in teaching, so that students can use their mobile phones to learn oral English for 5-10 minutes every day, listening, playing, reciting nursery rhymes and singing.

　　The reply of the school’s official WeChat also indicated that "teachers don’t know, and most parents don’t know" about the function of the software "parents buy learning beans to contribute to the class and reward students".

　　The official WeChat also said that "buying learning beans" is a business bound on the "parent client", which is mainly to open up a participation channel for parents. Parents only need to spend a little money to buy learning beans and increase the number of classes to reward students’ learning on the platform. According to software companies, the proportion and amount of parents’ behavior of "buying beans" are very low.

　　At the same time, the official WeChat said that it would suspend the use of this homework platform, and make a decision according to the opinions of all parents after the teachers and parents of these classes have fully communicated and discussed.

　　At the same time, the relevant person in charge of the software company said that at present, they have closed the function of parents "contributing to the class to learn beans".

　　Education expert: "learning beans" is unnecessary, gilding the lily.

　　After understanding the concept of "learning beans", education expert You Yong said, "It’s very awkward and unnecessary, which is really too utilitarian." He believes that in online software, parents’ intervention will weaken the sense of self-learning responsibility of children, which is also the performance of impetuous school management.

　　"In fact, the achievement itself is a reward." You Yongheng said that the adoption of this kind of software is only that the school is led by the software company, and the designer of the APP does not know much about education. In this process, the involvement of parents would have triggered a comparison, and some parents have invested in all aspects of their children. "More let nature take its course, less reward." He said that too many rewards are just gilding the lily.

On April 18th, Chery started the pre-sale, and the new car launched a total of four configuration models, with the pre-sale price range of 159,900 to 199,900 yuan. Fengyun T9 positioned a compact SUV equipped with Chery C-DM hybrid system.

At the pre-sale conference, the official said that 9.9 yuan can participate in crowdfunding or lottery if it orders. When the total order volume is less than 10,000, the listing price will be reduced by 5,000 yuan, and so on, the highest price will be reduced by 20,000 yuan.

Fengyun series is a brand-new energy sequence of Chery brand, which was officially released in November last year. At the same time, it will adopt a brand-new product Logo, and it will launch 11 brand-new models in the next two years, based on Chery Kunpeng’s super C-DM hybrid technology.

Under Chery’s new energy brand system, there are currently four new energy brands: Chery New Energy, Jietu, Xingtu and iCAR, and the Fengyun sequence in Chery New Energy has been restarted into a hybrid brand, and Xingtu’s Star Era is defined as the high-end brand of Chery New Energy.

Fengyun T9 Appearance & Interior Appreciation

As Chery’s brand-new energy sequence, we feel a strong "new energy smell" from its front face design. The front face of the new car adopts a large-area closed grille, but the traditional grille position still adds matte silver trim strips to outline the shape, which is very aura as a whole, while the air inlet for the engine is hidden under the front face.

Coming to the side of the car body, Fengyun T9 uses privacy glass in the back row, and there are not too many complicated lines in the whole car body. The shape of the traditional SUV benefits from the size and also shows its gas field.

The detailed design part, now hidden door handles, large-size wheels and so on have been given.

In terms of body size, the length, width and height of the new car are 4820X1930X1710mm and the wheelbase is 2820 mm.

The shape of the tail echoes the front face, adopting the design of penetrating taillights, with Chery’s LOGO in the center, and the whole tail seems to have a wide horizontal vision.

In terms of interior, Fengyun T9′ s style is also consistent with the current mainstream. In the center console of the car, there is a large-size floating screen with an estimated size of 15.6 inches, and it is expected to be equipped with Qualcomm Snapdragon 8155 chip, which will bring high vehicle performance and look forward to the subsequent static performance experience.

The main driving instrument also uses a separate floating screen with an estimated size of 10.25 inches.

Other features include zero-gravity seats, wireless charging function of large wattage mobile phones, ventilation, massage and heating of front and rear seats, and other comfort configurations.

In terms of power, Fengyun T9 this time is a hybrid model, with Kunpeng power, 1.5T engine, 3DHT gearbox and CDC suspension system. There will be two versions of two-wheel drive and four-wheel drive. The maximum power of the two-wheel drive motor is 165kW, and that of the four-wheel drive motor is 340kW.

In terms of battery life, the two-wheel drive CLTC has a pure battery life of 160km, and the four-wheel drive version is 150km；; The comprehensive mileage of two-wheel drive and four-wheel drive is 1320km/1100km, respectively, and the power loss and fuel consumption are 5.7L/100km.

C-DM hybrid system

At present, Chery is fully turning to new energy sources, and the hybrid field relies on the Kunpeng super-performance electric hybrid-C-DM independently developed by Chery, equipped with the fifth-generation ACTECO 1.5TGDI high-efficiency hybrid special engine and the third-speed super-electric hybrid DHT.

Under this platform, it can cover a variety of vehicles and power combinations, including A-B cars, SUVs and MPVs, 5-seat, 6-seat and 7-seat vehicles. In terms of power, it covers 1.5T, 2.0T and 1.5L hybrid special engines, as well as 13DHT and 3 DTH hybrid boxes with different power and torque.

Among them, the fifth-generation hybrid engine is the latest achievement of Chery in the hybrid field, and it has the technical applications of Miller Cycle technology, 4.0i-HEC fourth-generation intelligent combustion system, HTC high-efficiency supercharger, i-LS intelligent lubrication system, i-HTM intelligent thermal management system, HiDS high dilution system and so on.

The power system can achieve the maximum effective thermal efficiency of 44.5%, fuel consumption of 4.2L per 100 kilometers and maximum power of 115kW.

In the aspect of hybrid DHT gearbox, three-speed super electric hybrid DHT and stepless super hybrid DHT are also built. Among them, the three-speed super electric hybrid DHT is based on dual-motor drive and three-speed DHT, which has the characteristics of the highest transmission efficiency of 97.6%, acceleration of 4.26s per 100 kilometers, and torque distribution before and after 0-100%.

The stepless super hybrid DHT also realizes the driving state of non-inductive variable speed through E-CVT, and also has the characteristics of pure electro-acoustic pressure level and average efficiency of 90%.

Long battery life is still popular.

The recently announced new energy penetration rate seems to have exceeded 50%, among which the sales of plug-in and extended-range vehicles with large batteries have performed well. From the perspective of car scenes, most car scenes in the city can use pure electricity and long-distance car oil without worrying about energy replenishment, which has become the mainstream car choice for domestic users.

Nowadays, the pure electric life of the vehicle is basically the same as the extended range, and there is no difference in experience. Therefore, the demand for such vehicles is still strong and will gradually replace the pure fuel vehicles. Just like Chery, it will launch 11 new plug-in models in the next two years, which shows that it has been accumulating power for a long time.

1905 movie network news On January 28th, the film directed and starring released the preview and poster, which was officially finalized on February 12th (New Year’s Day) and will be launched on the video platform. In the finalized poster released this time, Wang Baoqiang incarnates as a Shaolin monk, with a face full of righteousness and condensed the soul of Shaolin.

In the trailer, we not only narrate the journey of this filming dream, but also return to Shaolin disciple status to make great efforts. The film shows the pure retro kung fu temperament, which is expected to drive a new wave of family watching movies.

"The strongest dreamer" Wang Baoqiang filmed Shaolin after 30 years.

In the poster released by the film The Legend of Shaolin Temple this time, under the background of gilded texture, the three scarlet characters of "Shaolin Temple" are full of vigor and vitality, which embodies the antique and vigorous Shaolin charm. In Chinese characters, Wang Baoqiang incarnates as a Shaolin monk. The golden rooster is independent and stands upright, just like a golden pine, and punches sideways, which fully shows the martial arts cultivation of Shaolin disciples.

It is reported that this poster is a tribute to the classic kung fu film starring. In the notice released in the same period, Wang Baoqiang claimed that the idea of making this film had already been planted 30 years ago. At the age of eight, the open-air screening of Shaolin Temple in the village made him determined to study martial arts in Shaolin and make a movie. The actor’s dream has been realized for 30 years, but the dream of "making a Shaolin movie" has always called him in his heart.

In the second half of the preview, in the voice-over of "You are a descendant of Shaolin", the role in Wang Baoqiang’s film officially appeared. He not only practiced the five unique skills of the whole knife, gun, sword, stick and cudgel, but also stayed in the countryside and did not forget to realize the true meaning of Shaolin during hard training. No matter in the secular world or Zen family, he was open to the world with his "Shaolin martial spirit" and showed his true colors.

It can be said that, from a grassroots background, to a well-known actor with high nationality, and now, together with Tang Jili, the director of the gold medal action film, he made a dream of Shaolin, Wang Baoqiang fully explained what is the "strongest dreamer". The Legend of Shaolin Temple, which was filmed with such sincere and valuable sincerity, is worth the audience’s expectation.

Jin Dao Shao Lin’s true colors and pure kung fu movies

In recent years, Wang Baoqiang has successfully performed many impressive comedy roles in a series of acclaimed and popular commercial blockbusters, such as "A Man on a Long Road", and has become a "Happy Harvester" that makes the audience feel more cordial. However, in the preview, he changed his old image and became an orthodox Shaolin monk. His posture was solid and steady, his movements were powerful, and his martial arts skills reached the point where he completely subverted everyone’s previous stereotype of him as a "comedian", showing the true nature of Shaolin disciples and his solid martial arts skills.

It is worth mentioning that, with the classic singing of Shaolin Shaolin, Wang Baoqiang skillfully wields swords and sticks, practices hard in spring, summer, autumn and winter, and meditates and realizes the righteousness of the people, which has the charm of the Jet Li version of Shaolin Temple. It is precisely because the film shows the rare pure "retro martial arts film" temperament in today’s era that it can not only hook up the beautiful nostalgic memories of a generation of "martial arts films", but also make the new generation of viewers experience the pure pleasure of action films, so it is very suitable for men, women and children to watch in the same room.

"The new Braille books in the library are clearly printed, and the current Braille is used correctly, which is very suitable for blind people to read. There is also a special reading table for us blind people. How thoughtful! " On May 4th this year, in the reading room for the blind of Hefei Library, Mr. Jiang, a visually impaired person, said happily to You Yi, assistant procurator of the Third Procuratorate of Shushan District Procuratorate of Hefei.

Teacher Jiang experienced this change in Hefei Library, which benefited from the first administrative public interest litigation case of visually barrier-free information construction in our province handled by Shushan District Procuratorate. In January last year, the prosecutor of the hospital found that the daily reading needs of visually impaired people with disabilities were difficult to meet, Braille books were expensive and difficult to buy, and the borrowing process in some libraries was not smooth. After visiting local disabled persons’ federations, public welfare voluntary organizations and relevant administrative organs, and listening to the opinions of the visually impaired, the prosecutor further learned that the reading room for the blind in Hefei Library could not be used normally, and the configuration of barrier-free information exchange equipment such as Braille books, audio books, voice recording, large character reading equipment and software was not perfect, which made it inconvenient for the visually impaired to borrow. In view of the fact that the reading rights and interests of visually impaired people have not been effectively guaranteed, and the social public interests have been infringed, under the guidance of the provincial procuratorate and the designated jurisdiction of the Hefei Procuratorate, on April 12, 2022, the Shushan District Procuratorate filed an administrative public interest litigation investigation.

Since then, the hospital has held a round table meeting with relevant regulatory authorities to discuss the statutory duties of administrative organs, the implementation of the demands of disabled representatives, the rectification plan, and regulatory measures, and clarified the direction of rectification. On April 15th, the Procuratorate of Shushan District issued a pre-litigation procuratorial proposal to Hefei Culture and Tourism Bureau, stressing that promoting barrier-free environment construction is an important prerequisite for ensuring the disabled and other social members to fully and equally participate in social life. Information accessibility is an important part of barrier-free environment construction and an inevitable requirement for building an information society in an all-round way and promoting social fairness and justice. Hefei Library, as a subordinate unit of Hefei Culture and Tourism Bureau, has some shortcomings in the guarantee of barrier-free information construction. The bureau is responsible for the development of urban public culture and should perform its supervision and management duties according to law to avoid the infringement of social public interests. In view of this, according to the Public Library Law, Regulations on Barrier-free Environment Construction, Regulations on Protection of Disabled Persons in Anhui Province and Administrative Measures on Barrier-free Environment Construction in Anhui Province, this proposal requires Hefei Library to allocate Braille books and related reading equipment according to regulations, optimize the lending process, improve the construction of barrier-free information, and ensure that special groups can enjoy social public cultural services equally.

After receiving the procuratorial suggestions, Hefei Municipal Bureau of Culture and Tourism attached great importance to it and decided to launch a special campaign of "protecting the reading rights of visually impaired people" throughout the city, urging more than 30 libraries in Hefei and related communities to improve the construction of visually impaired reading facilities in time, speed up the transformation of information barrier-free environment, ensure the normal use of reading rooms for the blind, and at the same time, add existing Braille books for social sciences and literature. For this special rectification, Hefei Culture and Tourism Bureau gave a written reply to the Shushan District Procuratorate.

In order to consolidate the results of public interest litigation, on May 4th this year, the Procuratorate of Shushan District specially invited three representatives of visually impaired people and two volunteers of procuratorial cloud platform and supervisors of barrier-free environment construction to walk into Hefei Library for "looking back". Everyone browsed more than 200 new Braille books purchased by the library and experienced the "network+mail" borrowing process and new barrier-free information exchange equipment such as a book listening machine.

In Hefei Library, the Procuratorate of Shushan District, together with the public welfare organization for the protection of the disabled, also held a forum on the spot with the theme of "helping the disabled with culture and reading the light". During the discussion and exchange, participants in the "Looking Back" fully affirmed the efforts made by the procuratorial organs in helping to protect the reading rights and interests of disabled people, and put forward opinions and suggestions on the optimization of Braille book procurement categories, the compilation of e-books, the improvement of online lending process of Braille books, and the promotion of offline navigation volunteer service. The relevant person in charge of Hefei Library said that according to the suggestions and requirements put forward by everyone, the barrier-free information construction in the library will be continuously improved to ensure that special groups such as visually impaired people can better share the achievements of social and cultural services.

"Now the needs of dyslexic groups such as visually impaired people have new connotations and are more diverse. As a procuratorial organ, it should help this special group to share more colorful cultural products in an equal and timely manner with the power of the rule of law." You Yi said. She also told reporters that in the process of handling a series of public interest litigation cases in the fields of transportation and barrier-free information reading, the public interest litigation department of the hospital found that seven disabled representatives who participated in barrier-free environment experience had difficulties in life, and they were transferred to the court as clues for judicial assistance. Complaint and prosecution department. After investigation and verification, the procuratorate issued them a total of 34,000 yuan in judicial assistance.

On October 18th, this administrative public interest litigation case of visually barrier-free information construction handled by Shushan District Procuratorate was jointly rated as a typical case of public interest litigation of barrier-free environment construction by the Supreme People’s Procuratorate, Ministry of Housing and Urban-Rural Development and China Disabled Persons’ Federation.
