The cosmetic surgery mentioned in the first two is not the cosmetic surgery in ancient China, but the cosmetic surgery in ancient China refers to changing the face shape through some makeup or masks made of leather, and changing a person's voice from the surface to another person with specific drugs, and it can be changed back when it is not cosmetic surgery. If it's cosmetic surgery, just take the knife once, then I don't think anyone will go back to do any cosmetic surgery.
