The valleys are deep and secluded in the territory. People suffer from "boats cannot pass" and sigh at the ravines. Under this circumstance, wooden arched corridor bridges came into being and became a necessary transportation facility in mountainous areas. According to the "Qingyuan County Chronicles" of Guangxu, since the Song Dynasty, more than 230 wooden arched corridor bridges of various types have been built in Qingyuan County. At present, more than 90 bridges are still in existence, which is the highest in the country. In September 2005, the Houkeng woven beam wooden arched corridor bridge in Qingyuan County won the UNESCO Asia-Pacific Cultural Heritage Conservation Excellence (First Prize) Award. Taishun County, Zhejiang Province, also preserves a large number of wooden arch bridges with braided beams, 15 of which are listed as national cultural relics protection sites. Among these wooden arch bridges, the Xidong Bridge built during the Longqing period of the Ming Dynasty has the longest history.
