A male teammate who appears unenthusiastic about work and avoids getting involved. He carries a Jingjiang thermos and sits in the back row. Despite his laid-back exterior, he is actually very smart and knowledgeable about case progress. He has a deep, unshakable hatred toward Tao Jiang because Tao Jiang suspected his younger brother of defection when the brother was actually an undercover agent who was captured, tortured to death, and found unrecognizable.
