Zhuang Yan Temple is located on the west side of the Drum Tower in the center of the old city in Chengguan District of Lanzhou City. Founded in the Tang Dynasty, it is said that it was the former residence of Xue Ju, a captain of Jincheng at the end of Sui Dynasty. In the 13th year of Daye (6 17), after Xue Ju proclaimed himself emperor in Lanzhou, it became his palace. After calming down the snow chrysanthemum in the Tang Dynasty, it was changed into a Buddhist temple, consisting of three courtyards: the mountain gate, the wing, the front hall, the main hall and the back hall. According to the literature, the Yuan, Ming and Qing dynasties have been repaired many times, and there are three existing halls.
Zhuang Yan Temple is famous for its sculpture, calligraphy and painting. The statue of the Buddha in the Hall of the Great Hero is symmetrical and vivid, and its clothing lines are delicate and realistic. The original mountain gate inscription "majestic and solemn hall" was written by Li Guang, a famous calligrapher in the Yuan Dynasty, and the font was vigorous and powerful; The Guanyin mural on the back wall of the Hall of Great Heroes is dignified and graceful, white as gauze, pure bottle of willow branches and green as new. After the founding of People's Republic of China (PRC), it was turned into a tourist attraction.
