Yudai Beach is a narrow and narrow beach peninsula, located in Wanquan River, Longguan River and Jiuqu River, which flow into the South China Sea. Over the years, Yudai Beach is composed of sea water and river water. Its length is 8.5 kilometers. It is recognized by Guinness as "the narrowest beach Peninsula separating the sea and the river". Standing on the beach of the Jade Belt, on the one hand, the Wanquan River is as calm as a mirror, on the other hand, the vast South China Sea is full of smoke, which is of special interest. The golden beach is beautiful, the snow-white spray splashes, very spectacular. But the sands are a little rough and crumbling.
