Xin Liangxiang lost his job and fell into poverty. One day, his wife fell ill, and Xiang stole milk to feed his young child. He was caught by a fat policeman, who fortunately let him off the hook. Later, Xiang, at Jia De's instigation, tried to swindle a jewelry store owner. After the scheme failed, he was arrested again by the fat policeman and sentenced to three months in prison. The fat policeman promised to take care of his family, for which Xiang was extremely grateful.
