Mother Wife

This story takes place in southern Fujian in the 1930s. Gao Yao Zong, the young son of the affluent Gao family, has been arrogant, rebellious, and sickly since he was a child. A Fu, a long-time worker, caused a fire due to poor care of the warehouse and had to marry his 17-year-old daughter Lin Qiu Ju to Gao Yao Zong, who is only eight years old (commonly called "mother wife" by the locals).
