《徐霞客游记·滇游日记四十四》
二里，向西越过冈脊，望见南山似屏风一样自西向东排列，这是排沙北面的山，西边起自洱海东面，东边抵达宾居，南边与大山脊乌龙坝山并列相夹，当地人称为北山，而观音臀在它的北坞。

Two li. Cross the crest of the hills to the west, and I see Mt. Nanshan standing like a screen in rows from west to east. This is the mountain north of Pai-Sha. In the west it begins on the east of Ear Lake, in the east it ends at Binju, and to the south it parallels the mountainous ridge of Wulongba Mountain. The local people call it Mt. Beishan, and Guanyin-Tuen is located at its northern edge.
