He wrote in "Records of the Western Regions of the Tang Dynasty" that "Jipanduo Kingdom is more than a thousand miles away, and the capital city of the country is on the stone ridge. There are many rivers on the back, the mountains are high, and the Kawahara is narrow." Jiepantuo Kingdom is now the Stone City. The large and small stones all over the city are said to be the throwing stones (used in ancient battles) carried by the soldiers who defended the city. Weapons for defense), city buildings were mostly built with stones, and the inner city was built on the top of a hill. Until the Qing Dynasty and the Republic of China, Stone City remained an important border guard post on my country's western border. With its long history, unique design, complex architecture, and solid structure, Stone City continues to play the role of the Silk Road. Today, Stone City has slowly become old and dilapidated in the course of historical evolution. It is a piece of ruins, broken walls, Overgrown with weeds and riddled with bullet marks, what is left to future generations are memories that cannot be dismissed, and a mysterious and sad feeling that is difficult to understand.
