Introduction to Laotieshan: "The top of Laotieshan goes deep into the sea, where the Yellow Sea and the Bohai Sea divide. From the west, rapids surge like clouds, and from the south, mist rises in response to the wind." This is the spectacular scene of the natural boundary between the Yellow Sea and the Bohai Sea located in Laotieshan. Laotieshanjiao, located at the tip of the Liaodong Peninsula, extends between the Yellow Sea and the Bohai Sea, forming a natural boundary between the two seas. The color of the sea water can be described as "clearly distinguishable". Part of the water in the Yellow Sea in the east is dark blue, while the Bohai Sea in the west appears turbid and slightly yellow. This is a natural phenomenon caused by the trench on the seabed where it is located.
