《徐霞客游记·滇游日记二十八》
路绕过山坡往北走，渡过坡北的山涧，马上顺着北面的山涧往西下走，共四里多，经过梅花哨，到了这里南北两面的山渐渐开阔起来。
路盘坡而北，渡坡北涧，即随北涧西下，共四里余，过梅花哨，于是南北两界山渐开。
The road bypasses the slope and goes north, crosses the mountain gulley in the north of the slope, and follows the mountain gulley in the north to go down to the west, a total of over four li. After passing through Meihua Sentry, the mountains on both sides of the north and the south gradually become open.
