Wei Changzhi is Zuo Cao's uncle-in-law, husband of Zuo Caiyun. He works sporadically at the tractor factory, spending most of his time gambling. He is described as a 'good-for-nothing' who uses his father's burial money for gambling debts. He is passive, feeling embarrassed by Wei Mu's behavior but not intervening effectively. He is the recipient of preferential treatment at mealtimes, with all meat given to him.
