Jiayuguan is known as the world's first Xiongguan. It is connected to the cantilever Great Wall of Heishan in the north and the first pier in the south. It is the westernmost gateway of the Ming Great Wall. It is also the traffic fortress of the ancient Silk Road. It was built about 9 years earlier than Shanhaiguan. In general, the Jiayuguan Association will look at the Great Wall of the Cantilever and the first pier of the world to help understand the first level of the world. Its very nice to shoot costumes here.
