Introduction to Wanghai Pavilion: In 210 BC, Qin Shihuang built Wanghai Pavilion on the top of Chengshantou Mountain. Due to the passage of time, the sea-viewing platform collapsed, and later generations built the sea-viewing pavilion. Standing in the pavilion and looking out into the wind, you can have a panoramic view of the scenery. If it's a cloudy day, when you climb up to the pavilion, you'll see misty clouds under your feet, making you feel like you're in a fairyland.
