Introduction to Huacheng Bridge: Huacheng Bridge is the center of the Three Bridges, 225 meters away from Wanyuan Bridge in the east and 122 meters away from Wankui Bridge in the west. This bridge, also known as Tang Bridge, is 46 meters long, 3.4 meters wide and 6.6 meters high. It was built during the Yanyou period of the Yuan Dynasty (1314--1320). It was originally built by two monks from Huacheng Temple in Tangkou, so the bridge was named after the word "Huacheng". It was rebuilt into a stone bridge in Jiajingzhong in the Ming Dynasty, and then rebuilt twice in the third year of Chongzhen and the fifty-eighth year of Qianlong in the Qing Dynasty. It has been over 430 years since it was rebuilt from masonry.
