The so-called Daihe is a river, is the boundary between Qinhuangdao City and Funing County. To the east of Daihe is the Beidaihe District of Qinhuangdao City, and to the west of Daihe is the Nandaihe Street of Funing County. Dongdaihe is far away from Suizhong County, Liaoning Province, outside Shanhaiguan, more than 60 kilometers away, and Daihe has no relationship. Just want to touch Daihe's light. No matter what the name is, as long as you can play in the sea and escape the heat, and this is cooler and more primitive than the South and Beidaihe.
