I came to Sanjiang County in a hot season. The county town is not very big. The two rows of close houses on the riverside formed Sanjiang County. It looked similar to the current buildings. It was not until I walked to his Moon Street that I saw the strong national customs. There is a highway wind and rain bridge. There is also this Drum Tower, which is located on the edge of its square, opposite the Bird's Nest, which is a small county worth seeing.
