Ma Chunlian is Qin Aiguo's mistress, also known as Widow Ma. She had an affair with Qin Aiguo while married to Luo Dazhuang. After Luo Dazhuang's suicide, she returned to her family and has lived comfortably over the years by pleasing men. Luo Chunhua blames her for her son's death, stating that if it weren't for her getting involved with Qin Aiguo, her son wouldn't have died. Qin Aiguo told Luo Dazhuang that Ma Chunlian followed him and lived in comfort, far better than staying with Luo Dahua, who was considered a useless man. Her relationship with Qin Aiguo had been ongoing for years and continued even after the events described in the text.
