In the small Chang'an town in the east of Luocheng, there is a beautiful river more than ten kilometers long, one by one Wuyang River. The two sides of the river are green and green, the strange peaks are endless, the mountain village is smoky, the river water is crystal clear, and the fish playing in the water is clearly visible. The boat travels on the river, the water surface is sparkling and changing. Under the Yayi Dam, countless stacks of water can be seen running down, with both sound and shape. The scenery on both sides of the Straits is a good landscape picture. There are thousands of ancient pine, turtles, rhino mountain, Makou mountain, and many other attractions along the river for viewing.
