Why do some people say that the roads in Chongqing are psychedelic?

The light rail in Chongqing often shuttles between mountains, waters and buildings, feeling like a roller coaster. So, if you live on the 10 floor and someone walks outside the window, don't think it's Spider-Man or a ghost coming to see you, just a passerby. At night, the Chongqing Grand Theatre, located at the intersection of the two rivers, has gradually become a place for local citizens to hang out after meals and take wedding photos, and has also become a new attraction for foreign tourists to travel to Chongqing. In recent years, the urban construction of Chongqing is changing with each passing day. "A map will be updated every three months", and all kinds of modern excavation equipment razed the previously insurmountable hillside to the ground. Many old shadows of this city can only be found in photos.
