As for where this mole came from, Sun Li had explained the reason in Weibo before. "Niangniang" had a serious car accident in June 2003, and the mole was also caused by broken glass.
Sun Li wrote in Weibo on October 6th, 20 1 13: "Ten years ago, I had a car accident and woke up with a mouthful of glass. Three days later, I pulled out a piece of broken glass under my chin. Today just now, I pulled out another piece of glass at the corner of my mouth, which has been with me for ten years! I want to frame it! Through this incident, I really feel like a man. "
It turned out to be the mole caused by this broken glass, but this mole made Sun Li more attractive and seemed to bring good luck to her career and family ~
