Last week, the location was slightly biased, if you go by car, it will take a long time. The locals in Yanyu Mountain also call Yanshan Mountain. They overlook Yanyu Mountain. They stand like a tall volcanic cone above the mountains, and the twin peaks stand like the tail of a swallow. Close-up looks like two or three feathers piercing the sky. This may be the reason for Yanyu Mountain's name. But more outdoor enthusiasts call it "Yuyu Mountain". I think the name may have really achieved a happy marriage in this mountain! Yanyu Mountain may have a clear bottom pool this year due to the many reasons for rain, and then pooled into a stream along the mountain. This is the fourth time I have been here, I have rarely seen such a pool before, but in winter, I can enjoy the beautiful ice waterfall here, especially spectacular!
