Living in Korea is very convenient. Everything is clearly marked in China. It doesn't matter if you don't understand it at first, as long as you can understand the numbers. It's hard to get lost in Korea, because in Korea, bus cards are swiped and subway stations have Chinese names. Most restaurants have pictures on their menus. Just point out what you eat.
In addition, there are many Korean China people in China and many overseas students, so their loneliness will not be very strong. /zd/xx
