A 19-year-old girl, who had received higher education, why did she do this? What was her relationship with him? Why did she kill him?... The outside world has various speculations about this, and these speculations make this case shrouded in mystery.
Why did she kill Mu Hongzhang
The reason for Zhang Chao's murder can be said to be the biggest mystery of this case, with different opinions from the public.
Some say: "It's all because of Mu Hongzhang's actions." After the kept-woman relationship was established, Mu Hongzhang treated Zhang Chao very well, usually depositing more than 30,000 yuan in her bank card every month. Once at a mahjong table, when Mu Hongzhang was not having good luck, he called Zhang Chao, and she helped him win 120,000 yuan, but in the end, Mu only gave her 20,000 yuan, which aroused Zhang's anger.
