The story is set in the 1970s in a small town in China. A middle aged couple has three children. The eldest son is obese and mentally challenged, therefore he is teased and outcasted by others. The second child is an outgoing and energetic daughter, who is not afraid of doing anything to pursue her dreams or to survive. The youngest child is a shy and quiet boy who is ashamed by his older brother and tries to break away from the misery in his family. Breaking into three sections focusing on each of these siblings, the film allows us to look into the lives of ordinary Chinese people the 70s.
