From Tangula Snow Mountain in the Northern Tibetan Plateau, the swift Yangtze River’s source, it performs a miraculous about-face at Stone Drum. First flowing south, then north, the river has shaped a dramatic triangle at an area of about 50 square kilometers. The extraordinary geological phenomenon of the First Bay of the Yangtze River has deeply influenced the formation of the river.

    The beautiful hoary Stone Drum is a town of vital military importance, which was chosen as a point to cross the river by Zhu Geliang, one of the most intelligent strategist in Chinese history. Kublai Khan, the grand-son of Genghis and founder of the Mongol Dynasty in China, and the Red Army led by Chairman Mao had been here.
