Travel route to Korea

I don't know how many days. I recommend a simple five-day itinerary:

Day1: Arrive in Seoul, depending on the time, you can go shopping and eat food in Myeongdong first. Shopping at Dongdaemun

Day2: Guanghuamen Square-Gyeongbokgung Palace-Changde Palace-Rensi Cave-Qingxichuan-Dongdaemun

Day3: Myeongdong-Ewha Women's University-(-Xincun-) Hongyi University-(-Hanjiang-63 Building)-Longshan Sparex

Day4.

If you are shopping, you can put it in the afternoon and evening, and go to places like Mural Village and Hongda in the morning without waiting to open the door.

Day5 is a bit biased. If you don't have enough time on the last day, you can give up and arrange to visit the hotel nearby.
