How to change the face of Chinese characters is definitely very effective, but I think everyone knows the problem of postoperative infection, so I personally don't recommend changing the face of Chinese characters through surgery. I suggest trying other methods, because the main reason of the Chinese character face is that the masseter is working, so I suggest that you eat less hard things and supplement more potassium at ordinary times, which can achieve the effect of thinning the masseter. Of course, you can also eat Yan Jia fruit directly, which is said to be rich in potassium.
