Introduction to underwater ruins: After the Xiaonanhai earthquake, all the houses around the lake were buried underwater, and the fields on both sides of the stream were submerged. After the trees were shaken by the earthquake, they also sank underwater, like drunken men. Geologically, they were called "Drunkard's Forest". There are too many extraordinary earthquake sites buried under the calm water of Xiaonanhai, which will become potential tourism resources in the future.
