Introduction to Sanduo Bridge: The three bridges are Baifu Bridge, Tianlu Bridge and Wanshou Bridge. Walking on these three bridges brings you many blessings, good luck and longevity, so they are collectively called "Sanduo Bridge". There are railings on both sides of each bridge, and there are jade pillars on the railings. There are 14 jade pillar heads on one side, 84 in total. So many jade carvings are gathered on these three Fu Lu Shou Bridge, so it is also called "the best jade bridge in the world".
