Buildings collapse in KangWang street
As you can see people knew something was wrong. Before the collapse, due to work on the subway, the workers noticed that something was very wrong. They went to the buildings and got everybody out on time. It's a miracle that nobody died or got hurt.
This kind of collapse has happened before in this area. The last time was in 2004.
