《徐霞客游记·滇游日记四十一》
如此二里，就坠下岭南的山坡，有时绕着壑谷向西转，有时上登山坳往东折，时上时下，又是五里，有两三家在山坳中建了房屋，这是兔威哨。
如是二里，乃坠其南坡，或盘壑西转，或蹑坳东折，或上或下，又五里，有两三家当坳而庐，是为免威哨。
After another two miles, I fell down the southern slope of the ridge, sometimes turned west around the valley, and sometimes went east over the mountain pass. It was five miles up and down again. There were two or three houses built in the mountain pass. This is Tuwei哨.
