Deyue Building was built in the second year of Guangxu and rebuilt in Yu Daqing (1876) and 1963. Deyue Building is a pavilion-style building with triple eaves and spires, with an octagonal base and a height of about 4 meters. The height is 20 meters and the width and depth are three. The second and third floors are wishful bucket arches, and the four corners of the first floor are supported by cornice columns, with natural corners. Colorful oil paintings and vivid carvings. Deyue Building is surrounded by water, with the plaque of Deyue Building and two front couplets inscribed by Mr. Guo Moruo. There is a pair of couplets that are Mao Zedong's poems, saying: the spring breeze is a thousand miles away, and the scenery is unique; Feiyu dragon three has millions of beautiful mountains and rivers. Another couplet was written by Lao Guo himself, saying: Longtan reflects thirteen peaks, the hidden dragon is in the sky, and the flying dragon is on the ground; Jade water is half a mile long, black jade is the body, and jade is the god.
