This is a well-known, must-visit place in Seoul. It's not only a public library but also a huge shopping mall. It would take a whole day to explore this place fully.
The local people also visit here over the weekends to read books and hangout with friends.
Here is an image of Sir. Park Hang-seo, the head coach of Vietnam national scocer team. His repuation went viral in Vietnam around the time I took the image. He successfully led the team to win the AFF cup in 2018. This image is to honor him. Thank you, sir!
