The Great Wall appears like a huge dragon with its head ducking deep into Bo Hai to paddle in the water and frolic among the waves, so the place is popularly called “Old Dragon Head”. It is located in the area 5 km south of the Shanhai Guang city, which is o­ne of the most essential parts in the military safety defense system of the Ming Great Wall, and o­ne of the most important scenic spots in Shanhai Pass Scenic Area. Old Dragon Head reaches deep in the sea in the shape of a peninsula.
