Introduction to Taigong Island: Taigong Island tells the origin of Jiang Shang and Yushan Shang Lake with its simple architectural style. It is the first stop to enter Shang Lake and is also a historical and cultural attraction that focuses on Jiang Shang culture. Jiang Taigong, who lived 139 years old, is a representative figure of longevity. The 139 characters "longevity" on the longevity bridge have different shapes, which are metaphors for the longevity of the Grand Duke. The bridge is 48 meters long and 12 meters wide. There are nine patterns in the middle of the bridge deck that symbolize good luck and wealth, including pine, crane, magpie, peony and butterfly. Wish the visiting guests a long life and continuous blessings.
