Bijia Mountain is 1620 meters from the coast, and there is a natural pebble passage connecting the island and land from the impact of the tide. It is commonly known as the "overpass" and also known as the "shen road". This "overpass" is a wonderful view as the tide rises and falls. Whenever the tide is low, the sea slowly retreats to both sides, and the passage is like a dragon of a dragon emerging in the sea. The tide is over, and the overpass is completely revealed. It is directly connected to the Bijia Mountain. Tourists can climb the island along this section of sand and stone roads. Whenever the tide is high, the sea is caught from both sides, and the "overpass" gradually narrows in the waves until it is completely hidden. At the "overpass" at low tide, you can also see small crabs under the stone, which is very cute.
