Highlights: Zhang Gong Cave lies on Yufeng Mountain, about 18 kilometers southwest of Yixing. The stalactites, stone curtains, and stone flowers are a feast for the eyes when lit up with multicolored lights. Duke Zhang's Cavern is also a famous location for film and television shoots. Scenes from productions such as Laughing in the Wind, Raccoon for a Prince, Mischievous Princess, The Story of Washing the Sword, and Tracks in the Snowy Forest have all been filmed here.
