Do I need a physical examination when going to South Korea?

No, it’s not necessary. Unless you come from a very serious plague area, like SARS in the past, when you arrive in South Korea, you will be asked to fill in your address and phone number when filling out the entry form. So I can find you if anything happens. It's simply not needed now.

I have been to so many countries, and I have come to the conclusion that the so-called overseas physical examination is a means for the Chinese quarantine department to make money. The first time I went abroad, I also took a physical examination and went to Japan, but no one paid any attention to you in Japan.
