The Dongjiang Dam in Chenzhou is called the first dam in Asia because it is the first hyperbolic thin-shell arch dam designed and built in China. The height of the dam is157m, the thickness of the dam crest is 7m, the center of the dam crest is 438m, and the normal water level is 285m. The Three Gorges Dam is a huge gravity dam. Not the same type, incomparable.

In the spring rain season, the lake swelled, the dam opened for flood discharge, and the green lake rushed down, plunging into the canyon, flying into thousands of water droplets, forming a huge fog and rushing to the valley, as if a huge silver forging floated down from nine days and instantly turned into countless colorful pearls scattered on the blue plate, which was spectacular.
