The Sangsu Monastery is situated at the foot of Mount Haibusi on the northern bank of the Yaluzangbu River in Jialang County. One of the first monasteries, it was built in 761 and is a typical Buddhist building. The fifth Tobu King Chisong Duosan sent envoys to Kashmir and India to invite famous lamas to teach Buddhism in Tibet. The monastery combines Tibetan, Chinese, and Indian architectural styles: the first floor is of Tibetan style, the second floor is Chinese, and the third floor is Indian. In each of the four corners of the main hall, a tower was built. Each tower is of a different color: red, white, green, or black.
