The development of history
Ya 'an has a long history, which was brought under the jurisdiction of the Central Plains Dynasty in the pre-Qin period. The history of human activities in China can be traced back to the Paleolithic Age, and "Fulin Culture" is an important cultural site in the late Paleolithic Age in southern China.
During the Warring States Period, Yuan Geng, the king of Qin Huiwen, was nine years old (the first 3 16), and Shu County was established after Qin destroyed Shu. Tsing Yi Road in the area is opened for posting mail. After that, Qiang people moved into Ya 'an along Qingyi River, which is the ancient residence of Qiang people in Qingyi River.
In the twenty-fifth year of Qin Shihuang (222 BC), Qin destroyed Chu, and the family moved here, so it was called Yandao (governing the capital). Subordinate to Shu County, this is the earliest organizational system in Ya 'an.
In the sixth year of Ding Yuan (11/years ago), Emperor Wu of the Western Han Dynasty moved the capital to Li Shen County (now Hanyuan County), and administered Yandao County (now Yingjing and Ya 'an in the period of Wang Mang), Qingyi County (now Lushan County), Migration County (Shiyang Town, Tian Quan) and Fangxian County.
