13 Stories of teenagers, 13 memories of youth. Some people see memories, some people see the past, and some people see themselves. Nancheng is a fictional inland heavy industry town written by Chen Hongyu. It does not exist, but it has the common shadow of so many small towns. Its streets are as hard as iron, its air is as silent as an enigma. It was once confused, chaotic and helpless, but now it has lost the antiquity of the old city and put on a modern coat.
