Mt. Dabijia Island in Tianqiao Town is located 35 kilometers south of Jinzhou, with an area of 1 square kilometer and an elevation of 78 meters. There are three peaks in the shape of penholders, hence its name. Between the northern bank and the island there is a 1.8-kilometer natural passage named the Heavenly Bridge, which disappears and appears with morning and evening tides. There are also ancient structures, such as Luzu Pavilion, Wumu Palace, and Sanqing Tower.
