The third step of Shancheng is Chongqing's most characteristic Slope Slope (stairs and uphill roads). The old buildings along the way are also the embodiment of the charm of Chongqing Mountain City. The third step is the most beautiful scenery in the existing trails in Chongqing. One of the most popular suspended plank roads built on the steep wall is the only urban plank road built on the cliff in Chongqing. Opposite is the rolling Yangtze River, which is a good place to see the river. Painted in the goose-yellow plank road railing, built in the volley, next to the plank road is the ancient city wall of Chongqing with more than 2,300 years of history.
