Xu Xian didn't correct his teeth. Tae-yeon's teeth have been restored. Her teeth were irregular when she was a child, but they will change a little when she is older. For the change of her face, squeezing massage can change it, not necessarily cosmetic surgery. It is said that cosmetic surgery is a deep-rooted concept in South Korea. As long as she is beautiful, she feels that it has been done. A while ago, it was reported that Xu Xian and Yun Er were pure natural beauties! Don't believe unnecessary rumors.
