Introduction to Qingliang Gate: This city gate was once closed, and most of the surrounding area is not like the previous urn city, because it looks very desolate under the bridge. If you continue walking north, you will encounter the famous "Ghost Face". Therefore, outside the city wall, there was once a place where the Yangtze River flowed. The river washed it all year round, and the huge rocks on the city wall formed a natural landscape like a ghost face. It is a must-see in Nanjing's Ming City Wall. One of the attractions to see.
