Archway of Gongchen Tower in the ancient city of Weishan, Dali

Gongchen Tower is the north gate of the ancient city of Weishan, which has a history of more than 600 years. It was originally a three-story building and was changed to a two-story city tower after more than 200 years of use. The plaque hanging in front reads 'Looking at the Sky from Thousands of Miles', but the 'Leading Six Chieftains' hanging behind is more imposing, symbolizing the glorious history of the Nanzhao King unifying the six chieftains. The side of the city tower is also very beautiful, with tourists dressed in Bai ethnic costumes taking pictures from time to time. The surrounding streets are clean and spacious, and the shops are well-organized.
