Introduction to Jiangnu's Tomb: In the sea more than 200 meters away from the shore, there are three huge rocks standing, about 20 meters above the sea. According to folklore, this is the place where Meng Jiangnu threw herself into the sea and was buried. At low tide, a plank road paved with boulders in the sea appears vaguely from the shore to the reef, which can reach directly to the foot of the reef.
