Mei grew up beside Princess Don Jia Gui. At the age of eleven, Princess Don Jia Gui gave birth to her son. De Fei was afraid that she would not be close to Mei with Princess Jia Gui, so she buried her son herself. May 4th just came to invite Princess De to play with him. Princess De believed that the May 4th Movement was evidence of her crime, and she never dared to face it. May 4th told Princess De that she actually saw nothing and knew nothing.
