Historical evolution

In the second year of Yuanshuo, Emperor Wu of the Han Dynasty (127 BC), Nie Chi, the chief of the tribe, came to the Yalong area of Naidong from jinbomi. He was hailed as the leader of the Yalong "fan" tribe and became the first Zanpu in Tibetan history.

In the early 7th century, the Tubo regime rose in today's Naidong Changzhu area, and Naidong was under the jurisdiction of thousands of waruyalong households. After the fall of the Tubo regime, the son of zamprandama, Watson, took Changzhu as his stronghold, and later became the ruling center of King jue'a of Yalong built by Watson's descendants.

In the second year of Duanping (1235) of the Southern Song Dynasty, after the rise of pazhuwan, Naidong became the central area of pazhuwan, and established such manor temples as halugang and Kaduo in Naidong, under the direct jurisdiction of Jinka.

In the 13th year of Zhizheng reign of Yuan Dynasty (1353), naidongzong was established.
