In 622, in order to avoid the name to be same with the Prince Li Jiancheng, the county was named as Gao'an. According to Taiping Huanyuji (《太平寰宇记》), "the terrain is high but flat, so name it Gao'an" (“地形似高而安，故名”). (Gao in Chinese means high, An in Chinese means flat.) In 624, Gao'an belonged to Yunzhou.
