Introduction to Santan Waterfall: There is another waterfall at the source of Tianti Waterfall. The water flows down through three layers of mountains, with twists and turns, forming three deep pools. What is particularly strange is that the mouth of the third pool is formed by two huge rocks facing each other. One stone is shaped like a snake head, and the other is shaped like a turtle, forming a "turtle and snake locking the river" trend. The locals call it Santan Waterfall or Sandie Waterfall.
