Zhou Momo's youngest son and Xie Xian'er's milk brother. He occasionally visits Luoxia Courtyard every two or three months since Zhou Momo stopped returning to the estate. He brought Xie Xian'er a used book and a kitten named Taiji. He helped Xie Xian'er investigate the truth about her origins, spending his saved pocket money on the task. He revealed to her that rumors claimed she was Prince Xie's biological daughter with a disgraceful birth mother, not an adopted daughter as told.
