A tall, handsome man in military-style clothing (khaki shirt jacket, white undershirt, military trousers, brown leather belt). He is actually Lin Yunchu's biological brother—they were switched at birth in the hospital. He grew up with Lin Keke, who he believed was his sister, but later learned the truth. He recognized Lin Yunchu on the train because she looked like his mother when young. He followed her to the town out of worry for her safety. He helped identify the kidnapped child Pei Yinyao and made a phone call to confirm her identity from their commune.
