Li Xian's roommate, a 17-year-old male patient with autism. His symptoms include refusal to communicate, mild language impairment, and stereotyped behavior patterns. He was admitted on June 5 and has been in the sanatorium for at least a year. He communicates minimally, mostly through gestures and drawings. He seems to have forgotten his real name. He is terrified of afternoon treatment. He drew stars but had never seen the sun, only pointing to the pitch-black outside the window.
