《徐霞客游记·滇游日记三十八》
东山就是虎坡大脊的山脉，有岔路通向东，越过山脊是去新建的青江坝的路，是进府城的近路。
东山即虎坡大脊之脉，有岐东向，逾脊为新开青江坝道，入郡为近。
The east mountain is the mountain range of the Hu Po ridge, with forks in the road leading to the east, over the mountain ridge is the way to the newly built Qing Jiang Dam, which is a shortcut to the government city.
