Take a person I knew a long time ago as an example. Before, a girl had an operation in a foreign hospital because of the problem of "puffy eyes", and after she finished it, she has reached a transformation.
But she was not satisfied, so she kept seeing different doctors. Every doctor's advice was: No need to do it! But she still felt that she didn't look good, so she went to another hospital for plastic surgery. ...
In fact, plastic surgeons in regular hospitals are not what everyone thinks. In order to make money, they will do surgery to make their clients beautiful, and doctors will also communicate with their clients about facial morphology and fitness.
If you meet customers who don't need to improve parts, you will discourage them!
