Nanshan Park, Seoul's most famous park. Here the tour guide gave 20 minutes to visit, and repeatedly warned not to go to the top of the mountain, because the time is not enough. It's not interesting to walk around Seoul for 20 minutes and see their two national heroes. In fact, the best view of Nanshan Park is on the top of the hill, which can give a bird's eye view of Seoul. There are some scenic spots on the top of the hill. Unfortunately, I didn't see them this time. I hope I can have a good time next time.
