There are two kinds of plastic surgery, one is to repair the appearance of people with physical defects, and the other is to have plastic surgery for beauty. The former is easy to understand, such as cleft lip and palate, which can return to normal. Some people have trauma, repair their faces, such as burns, and even have surgery to change their faces. These are all to restore basic physiological functions. I don't want to look good. The latter is purely for beauty. In fact, when I am old, it is a good thing to make my whole face more energetic through some simple face-lifting operations. More young women have plastic surgery for beauty. Common ones are eyebrow tattoo, double eyelids, rhinoplasty, breast augmentation, bone cutting, tooth extraction and so on. What is even more shocking is the increase of fractures, that is, the leg is broken first and then elongated with instruments. The process is like torture, and it lasts for several years with a high failure rate. Interestingly, plastic surgeons, no matter how ugly they think they are, are usually above average in the eyes of ordinary people, and even very beautiful ones abound. In fact, no one is perfect, everyone is not a standard face, and it is meaningless to have a plastic surgery into a standard face. For example, star cosmetic surgery, the new "A Dream of Red Mansions" cast has many roles, but almost everyone has a standard face, so how can the original "A Dream of Red Mansions" attract people?
