Beijing Miyun Bailongtan

Since the Han Dynasty, according to the saying that Yinglong can make clouds and rain, a white dragon has lived in the deep pool for a long time, spreading drizzle widely and benefiting the common people. Su Zhe in the Northern Song Dynasty wrote a poem that "the white dragon drinks the pool in the daytime, repairs the tail and hangs the back wall".
