Most of the characters in Akira Kurosawa's film are domineering samurai, but this film is unusual and uses happy strokes to write about how a pair of young and sad lovers put all kinds of troubles behind on Sunday. The film is also the first Japanese film to directly reflect the feelings of young people about sex, and the hero creates a courtship plot to his lover Changzi, which fascinates the young audience at that time. A couple of lovers fantasize about the future operation of a small restaurant in the ruins.
