Introduction to Dishui Rock: Dishui Rock is located on the east side of the mountain road. It is a naturally formed cave. Water drips continuously in the cave all year round and gathers into a pool. The water color is bright green. It is called "Longtan", also known as "Black Dragon Pool" ". In midsummer, the pool water seeps down, and the waterfall is like a rainbow and a curtain. It is extremely refreshing to drink from it. In summer, pearls are splashing everywhere, and it is refreshing; in winter, icicles hang upside down, just like a world of jade. Legend has it that the stone tiger formed by the stalactites at the entrance of the cave appeared and scared off the Tu family soldiers, saving Cheng Ying and Zhao Wu for the third time.
