Hi, zhaoyun, the idea of this theme is come from some students from HongKong, they have creat some different types of coffins to let people pre-experience the death. The idea of this theme is not shocking people into an awareness of mortality. Actually, this activity is wish people thinking about the meaning of death through the pre experience of death. Many people may not think about death. Because they think it is very far. I think this activity is very good to encourage people to do what they want to do in time or more cherish every day of life.
