Four centuries ago, during the Wanli reign of the Ming Dynasty, builders under the Mu Chieftains assembled the Qinglong Bridge. They chose a single-arch design, hauling massive stone blocks to span the Qinglong River in Shuhe Ancient Town. The bridge measures twenty-five meters in length, four and a half meters in width, and four meters in height. The planners aligned its central axis precisely with Jubao Mountain to the west, anchoring the structure to the geography of the valley.

For generations, this stone crossing served as a passage along the Tea Horse Road. Countless traders and horse caravans crossed these stones, carrying tea and goods toward Tibet. Today, the heavy stone slabs on the deck are mottled and polished smooth by the clatter of iron-shod hooves and straw-soled shoes. Visitors can run their hands over the cold, weathered surfaces, feeling the physical grooves left by centuries of labor.

The bridge is a quiet observer of seasonal shifts. In early spring, the weeping willows along the riverbanks sprout fresh green leaves, draping the stone arch in a soft, mist-like canopy. This scene is celebrated locally as Misty Willows by the Serene Bridge. Beneath the arch, the clear, rushing waters of the Qinglong River flow toward the Yangong River.

Human stories are etched into the stone. Travelers search the deck for a depression known as the immortal's footprint, which local folklore attributes to the Tibetan Buddhist master Karmapa, who supposedly leaped from this spot toward the Yulong Snow Mountain. In 2005, director Zhang Yimou used this ancient backdrop for his film Riding Alone for Thousands of Miles, adding a modern layer to its long history.
