Longzhu Lake is a big lake connected with Shuiyueyan. There are more than 20 hectares. The east, north and west of the lake are surrounded by the Rocky Mountains, and the south is a vast field. The two buildings in the east are located side by side with a gap in the middle, which is also the entrance of Longzhu Lake. There is a road around the lake along the foot of the lake, which enters from the east, bypasses the north and west of the lake, and then goes out from the south. By the lake, willows line up, the lake is crystal clear, there are countless fish, and the reflection of rocks can be confusing. 12 large and small caves were found in Shishan around the lake; Five natural cottages have been formed in the Rocky Mountains, some of which have been artificially built and built into military forts. Surrounded by the Rocky Mountains, the lake is clear and blue, weeping willows fly to the lake, and the huating in the lake is independent. Stalactites in the cave have different shapes, and strange stones stand out. To the south is a vast field. The whole scenic spot is integrated with lakes and light, and there is a scene of "as if isolated from the world". Xianfeng period in Qing Dynasty has become a tourist attraction.
