Walking along Shangzheng Street will take you to the water pier of the old town of Enyang, and the feeling of old Chongqing will come to you. The ancient town of Enyang is located at the intersection of two rivers. The location is very good and the water transport is developed. Therefore, it was also the distribution center of materials in northeastern Sichuan. It can reach Nanjing and Wangcang ascending to Chongqing and even Shanghai. Only the prosperity of the past has ceased to exist, leaving this ancient city of the millennium. Below the water pier is a flat stone bridge in the Southern Song Dynasty - Qifeng Bridge, which has been in existence for thousands of years. The slate of the bridge deck weighs 5 tons and has to praise the great construction skills of that time.
