Wudu Vientiane Cave Landscape

Moon Palace. The Vientiane Cave is shaped like a hole in the sky. Above the cave, there are big characters such as "There is a hole in another world" inscribed by prosecutor Gan Ningqing of the Republic of China and "Vientiane Cave" inscribed by Zhao Puchu. Entering the cave is a tall and spacious hall, which is the first scenic spot-the Moon Palace. There is a huge stone at the mouth of the cave, which looks like a lying animal, looking at the transparent stone cave in the shape of a full moon, like a rhinoceros looking at the moon and tourists.

Dragon Palace. Vientiane Cave passes through a smooth corridor with clouds on the ground and comes to the second scenic spot-Dragon Palace. There are two dragons squatting on the dam, and their scales are floating and shining, as if they fly at the touch. Passing through the manger is the Yellow Dragon Pool, and there is an immortal alchemy well, which is unfathomable.
