Introduction to Chicken Blood Waterfall: Located in the north of Tianjin Baxianshan National Nature Reserve, there is a natural canyon Shidonggou. The valley here is deep and dangerous, and the landscape is secluded. At the end of the deep valley is a waterfall more than 10 meters high. Because the large red algae forms a spectacle of chicken blood spilling on the rocks, it is called Chicken Blood Waterfall.
