Introduction to the Qiang King City: There are many Qiang walled city ruins on the mountain, and the remains of the ancient battlefield where the Qiang people and the Ming Dynasty fought more than 500 years ago - the Qiang King City. Qiang City surrounds the mountainside of Luofu Mountain. The east and west walls of the city are built with strips of stone. Today, there are still military and daily facilities such as general towers, sentry posts, and house foundations.
