Location: 75km northwest of Dunhuang
Description: Situated 75km northwest of Dunhuang, Yumenguan Pass was a strategic pass on the ancient Silk Road. Yumen in Chinese means the jade of Gate. It was so named because the jade of Hotan in what is now Xinjiang region was transported to central China through this pass. One poet named Wang Zhihuan had a famous line. ˇ®Beyond the Yumenguan Pass the breath of Spring has never crossed.' The mention of Yumenguan in the poem has made the pass all the more famous. The city is square, with well-preserved city walls and two gates in the west and the north respectively. The city wall is 10 meters high, three meters wide at the top, and five meters wide at the bottom. Both people and horses can go directly up to the wall.
