Introduction to the Chuanyanjiang Grand Canyon: It is located in the "primitive secondary forest of Daxiong Mountain". There are many rare animals and plants along the river. There is the only wild pigeon flower white orchid tree in Hunan, golden leopards and Chinese small salamanders, and the most mysterious one is Venus phoenix fern. The Chuanyan River is full of stones of various colors. The big ones are like walls, blocking the middle of the stream. The noble ones are like treasures. If you pick one up at random, it may be a moraine rock from 700 million years ago. There are pools everywhere in the river. It is green and clear, and the pond reflects ancient trees, vines, and exotic flowers and trees, creating a primitive scenery. Walking along the Chuanyan River, you will see many strange peaks and valleys. Because there are many mountains, there are flying waterfalls flowing into the Chuanyan River everywhere.
