Since China's first subway was officially put into operation in Beijing in 1971, the subway has been an indispensable part of urban transportation, effectively solving the problem of excessive crowds caused by obvious agglomeration effects in big cities.

  However, the development of the subway has not been smooth sailing.

  In the early days, there were no barriers between the subway platform area and the track area. Cases of delays in operations or even accidents due to factors such as people falling off the track or jumping off the platform were often reported in the news. As the urban population continues to increase, the subway has the characteristics of large passenger flow, short departure intervals, and short staying time at the station. Without any safety guarantee, a large number of crowded passengers are influx. If the subway platform does not have corresponding measures, Accidents falling into the track will greatly increase, and the piles will be shocking. In order to reduce the chance of such tragedies, in 2002, Guangzhou Metro Line 2 used an advanced screen door system in the subway for the first time. So far, subway screen doors have blossomed everywhere in the subways of major cities. Nowadays, subway screen door systems have almost become one of the standardized projects in subway construction.
