Introduction to Junshan Wanghai Scenic Area: During the Ming and Qing Dynasties, Baodugu was at the top of the mountains in southern Shandong. The shape of the mountain was like a gentleman sitting in a crown, overlooking the land of southern Shandong, so it was euphemistically called "Junshan". According to the "Yixian County Chronicles: Mountains and Rivers": "There is a Baodugu in Junshan, which stands thousands of feet high on the wall. It is 300 miles away from the sea. The weather is clear and the sea is like a sight." Junshan Wanghai is also known as the top of the "Eight Scenic Spots of Yi County" .
