If you go to Japan, first consult a doctor by email to evaluate the situation. First, make a general plastic surgery plan. On the day of surgery, the doctor will evaluate and adjust according to your situation. Surgery such as double eyelids and rhinoplasty is possible.
It would be better to find a Japanese plastic surgery hospital like Liberty Hill. There is a Shanghai cooperation project of Free Mountain Beauty and Plastic Surgery Hospital in Shanghai. You can go directly to a Japanese doctor and then go to Japan, which is more efficient.
