Introduction to Yingrui Pond: It is located at the pass of the eastern section of the narrow valley of Yunmeng Mountain. It was originally called Sanxi Pond and is the confluence of the three streams of Yunmeng Mountain, Qinglong and Longbei. Because the poets and poets of the past dynasties visited Shuilian Cave, it had the meaning of welcoming the clouds and gathering auspicious clouds, so it was renamed Yingrui Pond. There is a well in the pond called "Guigu Well", named in memory of Guigu. Every summer and autumn, the pond water overflows from the top of the dam, forming a spectacular waterfall.
