At the intersection of Qingshui River and Huan River, there is a temple called Panlong Temple. The founding date of this ancient temple in the deep mountains is now impossible to verify. It can be seen from the inscriptions that it was rebuilt in the thirty-fourth year of Wanli in the Ming Dynasty, and then it was rebuilt many times. The temple is built on a cliff, and there are more than ten buildings, large and small. Surprisingly, there is a huge natural cave named Jiangjiayan Cave under the cliff of Panlong Temple. There are many kinds of stalactites in the cave, which can be described as whimsy. Enter the cave, climb more than 30 meters, and reach the temple at the top of the mountain. The upper and lower stone steps in the cave are naturally formed, and it is interesting to enter the temple.

Even more amazing is that there is a shadowless mountain in the temple. Passing by Jiangjiayan Cave, I looked up and saw a grotesque hill and a strange peak standing in the temple. Half of the peak is suspended, and it seems that it may collapse at any time. There are statues of Buddha with different expressions carved on the top of the mountain, and there are niches beside the statues, as well as cliff stone carvings rebuilt in Xuande of Ming Dynasty and Kangxi of Qing Dynasty. The villagers in Jiangjiading told reporters that this ancient mountain peak of Panlong Temple is called Wuyingshan. Panlong Temple is also called Shadow Mountain because there is no projection when the noon sun shines on the mountain peak every summer solstice. There is no shadow in the mountains, there is no shadow in the mountains. A poet in Hebi once wrote a poem: "Rizhao Mountain has no reflection, and Taihang Mountain is wonderful and beautiful."
