Big S is a recognized role model of hard work in the circle. She has high requirements for people and things, and she is also very strict with herself, with serious obsessive-compulsive tendency. Compared with her sister Xiaoxiao's carefree personality, Big S seems to be much more tired. She debuted early and faced great pressure, and after many years of working in the entertainment industry, Big S once suffered from depression. During the live broadcast of an entertainment show hosted by her and Xiaoxi, she even said surprisingly: "I want to take a knife and kill my mother!" This statement caused complaints and protests from the audience. Later, Big S overcame her depression that had troubled her for many years through exercise and dietary adjustment.
