《徐霞客游记·滇游日记二十八》
此处的松树偏偏很茂盛，弥漫在山野遮蔽山谷，更无别的树，山坡用 松 来起名，很合适。
此处松株独茂，弥山蔽谷，更无他木，闻其地茯苓甚多，鲜食如山药。
The pine trees here are extremely lush, spreading over the mountains and countryside, blocking the valleys, and there are no other trees, so it is named Song (pine) on the mountain slope, which is very appropriate.
