On the coastal highway from Dagang to Shunhua, there is a section of highway near Haiyunling. It has been named one of the 50 Places in life by National Geographic magazine. The whole mountain road twists and turns along the mountainside, winding and rugged, along which the mountain scenery and sea scenery are beautiful and attractive. Up to now, the Vietnamese guard buildings and brick carvings remain in Haiyun Customs. Today it seems that although its appearance is not impressive, but in the past, it is a world-shaking, well-known.
