At the southern edge of the Weishan basin, where the Yangjiang River cuts through the valley, the Fengchuan Bridge stands as a monument of stone and brick. Originally vaulted in 1595 during the Wanli reign of the Ming Dynasty by a Dali native named Yang Sheng, this three-arched structure spans fifty-eight meters. For centuries, it served as a critical chokepoint on the Tea Horse Road, bearing the weight of caravans traveling south to Lincang and Simao.

The bridge is a physical record of human persistence and environmental struggle. In the summer of 1942, a catastrophic flood tore through the valley, destroying two of the arches. Local builders gathered in 1945 to reconstruct the crossing, laying down thirty-five meters of multi-span stone arches to restore the trade route. Walking across its 5.75-meter-wide deck, visitors can feel the rough-hewn masonry underfoot, worn smooth by the iron-shod hooves of thousands of pack mules.

The surrounding landscape deepens the story of the bridge. To the south, the historic Guanyin Pavilion once offered shelter to weary travelers. High above, on the summit of Fengchuan Mountain, the thirty-meter-tall Fengchuan Tower rises as a sentinel, built in 1854 to watch over the waters. At the foot of the mountain, the warm, sulfurous steam of the Mengzhao Hot Spring rises from the bathhouse village. According to local records, the mother of the Nanzhao king, Xinuluo, bathed in these waters to cure her ailments.

Together, the bridge and the tower form a unified heritage site, recognized in October 2023 as a Dali Prefecture-level conservation unit. The structure remains a quiet observer of the changing landscape. The rushing red waters of the Yangjiang River still flow beneath its stone arches, carrying the memory of ancient trade into the modern era.
