Safe Harbor Introduction: Beijiao has the tide of Luoyuan Bay, the seawater of Taiwan Strait, and the flowing water of Minjiang River. The three waters converge, forming whirlpools and undercurrents, making the seawater unpredictable. When passing through Beijiabi, experienced fishermen know how to sail close to Beijiabi. Many foreign ships who are not familiar with the waterway think that there are reefs near Beijiabi. In fact, it is more thrilling to stay away from the Beijiabi vortex and have more undercurrents. In ancient times, when a boat passed Beijiaobi, the fishermen called it "crossing the river." It was only after passing the river that it was said to be safe.
