《徐霞客游记·滇游日记十五》
从脊上往南望、南面五德山横贯南部天际，就是先前在洱海卫所看到的九鼎山西边高拥之山，山上有积雪的地方，到这里又东西横峙；其东又耸立着幕山，是所说的梁王山，两山之间稍低的山坳，就是从松子哨越过山脊往北走的地方。
从脊上南望，其南五德山横亘天南，即前洱海卫所望九鼎西高拥之山，其上有雪处也，至是又东西横峙；其东又耸幕山，所谓梁王山也；二山中坳稍低，即松子哨度脊而北处也。
Looking south from the ridge, Wude Mountain in the south spanned the southern sky, it is the mountain that I saw to the west of Jiuding Mountain before at Erhaiwei. There was snow on the mountain, and it stretched east-west once more; to its east, stood Musan, which is the so-called Liangwang Mountain. The mountain pass between the two mountains is slightly lower, and that is where you cross the ridge from Songzishao and head north.
