Introduction to Yintong Gorge: Yintong Gorge is the section from the mouth of Anxi River to Maodu Gorge. There are two dangerous shoals, Yintongzi and Zhanggongzi. Among them, there are high mountains, deep water, secluded valleys and wonderful scenery. During the boat ride, there are mountains and rivers. Again, the river flows twists and turns, like entering a maze, with flocks of mandarin ducks and egrets flying in the gorge. If you are lucky, you may even see the monkeys that have long since disappeared in the Three Gorges of the Yangtze River.
