Sister Qing, formerly known as Muyuan. According to Pingyang County Records of the Republic of China, it was called Chongzheng Township in the Qing Dynasty, Muyuan Township in the late Republic of China and Qingjie Township in 1935. 1992 "Withdraw, expand and merge", Log Township merged and was renamed Qingjie She Township again.

The origin of Chongzheng Township can't be verified, but there is still a saying about the origin of Muyuan. Qingjie, located in the valley, is surrounded by mountains (Bijia Mountain in front, sunset in the back, Jinzhongshan Mountain on the left and Mushan Mountain on the right), and three nearby streams gather here, hence the name. Where did that green street name come from? A folklore about the return of the prodigal son may be inextricably linked with this.
