1. The platform environment of the railway station has been improved, the grocery market has been demolished, a regular supermarket has been established, and the environment for people to rest by car has been greatly improved.

2. The management of the railway station has been strengthened, the platform environment has been rectified and standardized, and it is forbidden to set up stalls on the platform, which has reduced the chaos of the platform and improved the overall image of the railway station.

3. Driven by the work of creating a sanitary city, the railway station vigorously carried out environmental improvement, standardized food sales behavior, and strengthened garbage sorting to provide passengers with a more sanitary, comfortable and safe travel environment.

The model of the train has been upgraded. Most ordinary trains are replaced by air-conditioned 25T carriages. This kind of air-conditioned car can't open the window, so it can only come down from the door and get some air on the platform that stops for a long time, which basically reduces the trading space. There are not no restaurants on the platform, and some platforms also have some snacks operated by the railway.

The above are some possible reasons, I hope to help you.
