《徐霞客游记·滇游日记二十》
从村北往东下坡，一里渐渐平坦，于是往东在岭脊上走，岭脊左右两边逐渐夹成山坞。
由村北东向下坡，一里渐夷，乃东行岭脊，脊左右渐夹而成坞。
From the north of the village, go down the slope to the east, and after a li, it gradually flattens out, so go east along the ridge, and the left and right sides of the ridge gradually become pinched into a mountain nest.
