The Yarlung Zangbo River originates from the Gemayengzong Glacier at the northern foot of the Himalayas in southwest Tibet, and its upstream is called the Ma Quan River. It crosses southern Tibet from west to east, bypasses Nange Bawa Peak at the easternmost tip of the Himalayas, turns south, and leaves China via Pasigat. It is called Brahmaputra River after entering India and Jamuna River after entering Bangladesh. After Bangladesh joins the Ganges River, it flows into the Bay of Bengal.

Historical evolution of the Yarlung Zangbo River;

The ancient culture bred by the Yarlung Zangbo River has a long history, and the Neolithic culture in its basin is represented by Linzhi and Medog. Stone tools, pottery fragments, axes, chopsticks, chisels and other relics were collected in Linzhi County and Medog County.

In the late Neolithic period, many tribes were formed in various parts of Tibet. Around the 3rd century BC, Nie Chizanpu, as the leader of Yalong River tribe, first appeared in Tibetan history as Zanpu (meaning king) and established the Tubo kingdom of tribal slavery.

The Yarlung Zangbo River is not only the cradle of the birth and development of Tibetan civilization, but also the witness of Sino-Tibetan cultural exchange. In the history of Sino-Tibetan communication, the most memorable events are Princess Wencheng, Princess Fan, Princess Jincheng's wedding to the west and the monument of Tang-Fan alliance. They fully illustrate the flesh-and-blood ties between the Han and Tibetan nationalities and their cultures, which have their own characteristics and influence each other.

The Yarlung Zangbo River basin is rich and beautiful, which breeds fertile land on both sides of the strait and is the cradle of Tibetan culture. As a "Tianhe", the Yarlung Zangbo River has brought people in Xizang not only the past, but also a brilliant future.
