Wuhan flies directly to Seoul twice a week. Now direct flights to Seoul are not much more expensive than connecting flights. I suggest you forget it, because it is the first time to go to South Korea, and there are few international flights departing from Wuhan, so it is not easy to get confused, otherwise you may get dizzy at Capital Airport or Pudong Airport. When I first went to South Korea in 2003, I invited Little Red Riding Hood to bring it at the Capital Airport. Besides, when I get used to it, you can transfer in Shanghai, because Wuhan is more convenient to Shanghai.

When you don't understand the language, go to the supermarket to buy something, such as e-mart and HOMEPLUS. Don't talk, just pay. Besides, if you like, bring more beef jerky and melon seeds, which are not available in Korea. Daily necessities vary from person to person. Of course, they generally don't check whether to take beef jerky to Incheon Airport. If you fly from Shanghai to Cheongju, 89 people in 10 will be detained. Others are welcome to ask questions.
