The name of Longqiao originated in the Song Dynasty. The original wooden bridge was repeatedly built and destroyed. After the completion of the stone arch bridge, once and for all. During the late Qing Dynasty and the Republic of China, two rows of neat houses were built on both sides of the bridge deck. The house is not high, but it is exquisite, exquisite. The same color Qingtang tile house is exquisite and elegant. Signs are hung on the doors of all shops, and the business is mainly small handicrafts, such as copper pots, copper pots, hookahs, wooden combs, needlework, clothing, embroidery, oil cakes with local flavor, sesame candy and so on. All the shops are thriving and enjoy a good reputation in dealing in goods. In the 13th year of Shunzhi in Qing Dynasty (1656), the 20th year of Qianlong (1755) and the first year of Xianfeng (185 1), the bridge deck and the left and right banks of the bridge foundation were repaired successively, but the bridge body was always strong. According to the Records of Sanyuan County, in the forty-four years of Wanli in the Ming Dynasty, heavy rain poured down, the river surged, the raging flood crossed the bridge, the houses on the bridge deck were washed away, and the stone bridge did not move. On May 29, 2002, the wind roared, the rain poured down, the waves rolled and roared past, but the stone bridge was the mainstay and stable as Mount Tai.
