Male, Gu Siqing's uncle (son of Zhang Zhenyuan and Bai Yulan). He is a teacher at a school in the capital. He did not join the army. He first noticed Gu Siqing at a cinema because she looked like his late mother when she was young. He followed her out to get a better look. His sister getting lost as a child was an unhealed wound in the family, and seeing his cousin Gu Siqing helped resolve that pain.
