Introduction to the Longtangou Scenic Spot Square: The square in front of the square is entirely paved with granite stones. The Longtan Lotus Lake in the center of the square has ripples of blue waves. It is surrounded by colored lights under the night light and is connected by garlands. The left and right banks are the entry and exit channels for tourists. To the north is the mountain gate of the scenic spot. The tower, across the Longtan River, is tall and majestic, adding some beauty to the Longtan landscape.
