>>512748440Oh hey, the Chongqing subway line! I’ve been here! This is Caojiawan station out in Beibei district, which isn’t as developed as the other parts of the city and is far away from downtown. But as other commenters have said, it’s already well developed by now. Placing this kind of subway station entrance is a way for the city to get people to invest in housing and develop new areas of the city. Build a subway line exit in an empty spot, and watch as it explodes with new real estate development within the year.
Edit: For fun, google ‘Chongqing subway map’ and try to find Caojiawan station in the spaghetti bowl
