The homeroom teacher of Lin Erxia and Ren Jian. He is described as having a cold exterior but a warm heart. He intervened in the fight between Lin Erxia and Ren Jian, threatened to expel both if they didn't stop, and later showed understanding and compassion toward Lin Erxia. He encouraged her to focus on her studies and not ruin herself over someone insignificant. He gave her medicine and a handkerchief, and allowed her to skip class to clean her wounds. He also made both students copy the Red Quotations ten times as punishment.
