The exits of the Qiaosi subway station are the cool air for the public.

Coming to the Qiaosi subway station, it can be discovered that the corridors, aisles, entrances, and exists were full of people who had come to enjoy the cool air.

Coming upon the Qiaosi underground station one can see hundreds of people coming to enjoy the cool air. There are people in their pajamas with their family, someone with a laptop, someone lying on a sleeping mat, and kids chasing each other throughout the halls.

So as to divert these people who come to enjoy the cool air, and to prevent them from affecting the other subway passengers, in the mid-afternoon cool air is channeled on both sides of the hall. In this way those who come to enjoy the cool air are concentrated into a rather small area.
