Popularly known as Black Dragon Pool, the Yuquan (Jade Spring) Park at the foot of Mountain Xiangshan, north of the city of Lijiang.

The park derives its name from the fact that the water in the pond is clear and pretty, like a piece of jade. Upon entering the park, visitors encounter the Suocui Bridge, under which there are three small waterfalls running swiftly. A tower here houses numerous pictures and drawings on its beams, pillars, doors and windows. Today, this tower is used as a museum in which many precious historical cultural relics as well as calligraphic and paintings are displayed.
