The origin of the double-sided sea in Dongshan Island

The double-sided sea of Dongshan Island is formed by the interaction of seawater erosion and geological movement. On the south island of Dongshan Island, a natural wonder is formed between the outer sea area and the inner sea area. The waters around the island are about 200 meters deep and oval, with a total length of about 3.5 kilometers.

The double-sided sea is characterized by a hole leading to the inland sea. The depth from the hole to the inland sea is only 50 meters, while the depth in the open sea is 200 meters. This topographical feature not only attracts local fishermen to fish here, but also attracts many tourists to watch and explore.

In addition, the double-sided sea also provides a good ecological environment for the local area and becomes a paradise for fishermen to catch fish. At the same time, it is also praised by many geographers as a natural laboratory for scholars to study deeply.

On both sides of the double-sided sea, the sea water will meet here, so the middle road may be flooded when the tide rises. Therefore, you must pay attention to the tide table when going to Nanyu to avoid possible safety risks.
