② To fly to Korea, you need to fill in more travel declaration forms, which should be filled in English or Korean, and the telephone number must be accessible.
(3) All flights from China to South Korea must go through special entry procedures. The first step is to take your temperature and collect your passport. People with high body temperature should remember not to wear a coat after getting off the plane, so that their body temperature can return to normal. Wearing too much clothes and indoor air conditioning caused my body temperature to be high and was stopped. I must rest for a few minutes before I can continue to enter the customs.
④ After the body temperature is confirmed, a staff member will take it to the "Passenger Waiting Area with Unconfirmed Contact Information" to confirm whether the telephone number you filled in can be connected immediately. You can't enter the country until you confirm it. You can't leave your hotel phone number. So either open "international roaming" before departure or use "Korean calling card". If you have relatives and friends in Korea, leave their contact information, and you can enter the country after calling to confirm, but it is a bit risky and there is no guarantee that you can enter the country in this way in the future.
