What were the names of Ya 'an in ancient Sichuan?

In ancient times, this city was A Qiang in Tsing Yi, and Yandao County in Qin State (including today's Jing Rong and Yucheng District) belonged to Shu County. In the Western Han Dynasty, the migration counties (now Manchu), Hu Niu County (now Hanyuan) and Qingyi County (now Mingshan and Lushan) were added. In the Three Kingdoms, Shu Han settled in the county, and in Mengshan County in the Western Wei Dynasty. After the Sui Dynasty, the capital was moved to Yazhou. After the Revolution of 1911, Ya 'an Prefecture of Qing Army belonged to the 17th administrative supervision area of Sichuan and then to the 2nd administrative supervision area of Xikang Province. * * * In the early Republic of China, it was Ya 'an District of Xikang Province. Xikang province was revoked in 1955 and returned to Sichuan province as a special zone. Later, in 2000, it was changed to a provincial city.
