However, she had no opportunity to be a singer. Although kind to her grandson, she is very critical towards both her daughter-in-law, Yang Qin (Yijuan Li), and granddaughter, Xin Ran (Yin Hang), who openly treats Meng Jun with contempt for the way she treats her mother. This leads to Yang Qin fainting due to the pressure placed on her. After this incident, the family decides it's time for her to go to a nursing home.
