Bai Dingchang is the uncle of Bai Mengjin, described as a sanctimonious hypocrite. He appears fair and upright on the surface but is scheming and self-serving. When the envoy from Danxia Palace came to assess disciples, he caused Bai Mengjin to lose composure in front of everyone, making her miss the opportunity to join Danxia Palace directly and forcing her to risk the Tongtian Road. He is part of the Bai family that bullied Bai Mengjin in her childhood.
