Yumen pass began with the development of the Silk Road in the period of Emperor Wu of Han Dynasty. It is a major pass of ancient Chinese and Western civilization and commercial road. Wang Zhihuan, a poet of the Tang Dynasty, described Yumen pass in Liangzhou Ci that "why do Qiang flute complain about willows, and spring wind does not pass Yumen pass.". Since ancient times, poets and composers of all ages have described Yumenguan in countless ways. Now the wine fairy cave is also unfolding in the karst cave in southern China. Yumen pass is thousands of miles away. Only one person can pass by the narrowest pass, which is the real "one man is the gate, ten thousand people are not allowed to open".
