Introduction to Sanchaoshui Tiankeng Tidal Spring: Sanchaoshui Tiankeng Tidal Spring is a unique natural landscape, full of magic. The Sanchaoshui Tiankeng Tidal Spring Group has a total of 4 tidal spring points on the ground, namely Sanchaoshui, Qiandong, Longtan and Mofangwan are about 150-300 meters apart and are all skylights of the underground tidal rivers of Sanchaoshui. "Before you see its appearance, you hear its sound first." Standing on the roadside, you can hear the loud rumbling sound. After dozens of stone steps, you will go down to the bottom of the pit, and you will see the crystal clear spring water flowing from the north end of the pit. It flows out from the Guanyin Temple and flows underground towards the southern end of the Tiankeng. The Three Tides have a history of thousands of years. The tide rises and falls every two hours, and can rise and fall 12 times a day. There are three tides each time, hence the name "Three Tides".
