Jiayuguan is the transportation hub of the ancient Silk Road and the starting point of the western end of the Great Wall in Wan Li, Qin. Here, the "Silk Road" for economic and cultural exchanges between China and the West, which was opened more than 2,000 years ago, and the "ancient battlefields" fought by military strategists in past dynasties are faintly visible. This is the intersection of the Silk Road culture and the Great Wall culture in China, and it is known as "Hexi Town" and "Border Lock".
