《徐霞客游记·滇游日记四》
起床去观赏云南、贵州两省交界处的山脉，出了山峡口。又离开贵州省而进入云南省，高枕无忧地睡了一夜。
起观两界山，已出峡口，碧峒在西南山下，其北山冈上即红板桥，为贵州界。
I got up and went to view the mountains where Yunnan and Guizhou Provinces meet, before exiting the mountain gorge. I left Guizhou Province and entered Yunnan Province, where I slept soundly for a night.
