Introduction to Qilong Weir and Qilong Pavilion: Qilong Weir is a stone path along the west valley between the north and south peaks, over the mountain pass and down the east valley. It is built with neat stones, about 1 meter wide, and lined with trees. Thick shade blocks out the sun, and a stone monument of "Qilongyan" stands beside the road at the bottom of the west valley. A mixed-structure square pavilion, named Qilong Pavilion, was built at the point where the stone path crosses the mountain pass. A path built along the ridge to connect the two peaks also passes through the pavilion.
