Quick view of Dahan Gate and Chongli Gate in Seoul. Every day, there is a guard's antique changing ceremony. It happens that we meet each other. It's no wonder that we used to call "Seoul" before. Unfortunately, Chongli Gate is a rebuilt building. The original building was completely destroyed by fire in 2008. The security work is questionable. It also happened to meet the mascot of the "Pingchang Winter Olympic Games" in Seoul Square.
