Jing zhuang qing bu zi jin

A slob becomes rich by winning the lottery, moves into a better place and hires a bootlicking assistant. But he is bored with his wife and their sex life is a farce. Then his man-eating mother-in-law arrives on the scene and really livens things up. The guy buys his wife a restaurant to keep her occupied, which she turns into a sensational success. Then he begins to get jealous. (hkmdb)
