In The Lost Child, David and Li Sheng play the children's parents, Vision Wei plays the decadent Yuan Wu, Dany Lee plays the policewoman Zhang Ye, and Kelly plays the white-collar Lin Chuping. Even the supporting actors are familiar old actors with a strong cast.

The play tells the story of a child's disappearance in the process of going downstairs, which leads to a series of strange things happening in the neighborhood. The Lost Child is adapted from the novel Anemone. The story is bizarre and tortuous, and there are many original works, so don't worry.

The Lost Child basically continues the thread of Anemone, and the novel unfolds with narrative lines. Yang Yuan (David) and Fang Tao (Li Sheng), who live in Room 40 1 in a city community, are an ordinary couple. They have a son, Yang Mo, who has just entered primary school. Fang Tao will always be a "chicken baby". The couple often have conflicts because of their children's education, but on the whole, this is still a "normal" family, and there is love between them.
