Tao Xin's half-brother, 12 years older than her, now over 50 years old. He is a university professor and economically stable. He is childless and only has his wife for support. He harbored deep resentment about being a half-brother and refused to meet Tao Xin or be her guardian. He gave Chen Ping Zhou Tingzhi's contact information before throwing him out. His first reaction upon receiving the call about Tao Xin was to ask if her remains had been found.
