Introduction to Tianchi: The gentle slope basin in the mountains at an altitude of 700-800 meters in Yucang Mountain gathers many Tianding Lakes. It is said that there are Shibatian Lake in Yucang Mountain. Historical records include Longchuan Lake, Teal Lake, Langtian Lake, Mitong Lake, Changkengtou Lake, Yuhu, etc. The poet He Bai of the Ming Dynasty described Yucang Mountain Top Lake in his "Yucang Mountain Poems": "Golden light shines in the chaos of algae, and thousands of squids leap." Today, there are eight mountain top lakes in the mountain, with an area of several thousand square meters. They are also hundreds of square meters in size. Some of these mountaintop lakes are not connected to streams, but there are carp activities in them, which is amazing.
