Male supporting character, the child's second uncle. Tall man wearing tattered clothing and black-rimmed glasses, with unkempt hair making him look rough and disheveled. Single man who has never taken care of a child before. His nephew's parents are researchers at the 634 Institute of Aeronautics whose work is classified. He carries diapers, milk powder, and a baby bottle. Deeply grateful to Gu Qinghan and Wen Nuan for their help, nearly in tears from their kindness.
