I have heard of a method, but I don't know if it has any effect, that is, breast augmentation with books. You can do it under your arms on both sides, and then your hand will pull forward until you know where your arm hurts and you can't hold the book. You can practice your chest by practicing more every day. Of course, if not, I heard that it is also good to go to Ruili House for breast augmentation. I watched the program "I am a great beauty" on Hunan Satellite TV.
