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.

Since 1354, Naidong was the capital of the local government of Pazhu. During the period of Gandan pozhang local government, the land of Naidong was granted to the three lords by the local government of Tibet.

In 1751, the gaxia government was established. Naidong was subordinate to the gaxia government.

In 1793, the gaxia government set up Naidong sect, wenzaka sect in the north of the Yangtze River, and successively established several sects, such as Puzhang Jin sect, yadui sect, and then gaqu niecang in Zedang.

In 1909, the local government of Tibet established lokajiqiao in Shannan. Naidong sect and wenzaka sect still belong to the clan level, among which Naidong sect belongs to the first class and wenzaka sect belongs to the second class.

In 1956, the Preparatory Committee of the Tibet Autonomous Region established the naidongzong and Wenzong offices.

In March 1959, the democratic reform was carried out and the system of zongjin was abolished. In April, NAIDONG COUNTY was merged by Naidong Zong, Wenzong and pozhang, Zedang and yadui, which were under the jurisdiction of Shannan Jiqiao office, and the provisional Party committee of NAIDONG COUNTY of the Communist Party of China was established.
