Introduction to Huihe Mouth: It is located 4 kilometers southwest of Haorao Township in Zhalantun. The two rivers Chuoer River and Tuoxin River meet here, forming a huge water surface. After the two rivers merged, the giant dragon roared eastward at the foot of the mountain. The mountains and rocks on both sides of the bank are towering into the clouds, like jade pillars reaching into the sky.
