Talking About Hong Kong Island in the 1980S

In 1983, in the shadow of the Kowloon Walled City, a "hell begins" for time travellers. Chen Jiajun, an ordinary social beast from the 21st century, woke up and found that he had become a good-for-nothing young man in the walled city of Hong Kong who owed loan sharks and could be "killed" at any time. There is no system, no superpowers, only mold spots all over the house and a yellowed photo in his pocket - that is his only life-saving straw. On the back of the photo is the address left for him by the woman named "Sister May". In this black zone where no one cares, the law is useless paper and human life is like a piece of grass. In order to survive, he must use the "desire for survival" of modern social animals to fight against the "wolf nature" of the Young and Dangerous boys of the 1980s.
