It can't be said that all Koreans have plastic surgery, but most Koreans have had double eyelids. Moreover, Koreans don't think double eyelid surgery has plastic surgery, and rhinoplasty is also very common. These minor operations are not very expensive. There are also many plastic surgery websites in Korea. There is a website with Chinese translation. You can go in and have a look if you are interested.
