One of the attractions on Long Island is the boundary line between the Bohai Sea and the Yellow Sea

The boundary line between the Bohai Sea and the Yellow Sea is the line connecting Laotieshan Cape at the southern tip of the Liaodong Peninsula and Penglai Cape on the northern coast of the Shandong Peninsula. The seawater on both sides of this boundary line has different colors and salinity, forming a unique natural landscape. Under the lighthouse of Laotieshan Cape, one can clearly see the convergence of the Yellow Sea and the Bohai Sea, presenting a distinct and remarkable sight of 'clearly demarcated waters'.
