Longxing Temple is the great temple of Zhengding, and most of its surviving main buildings are Song work. The Moni Hall, of the Northern Song, has a cross-shaped plan with a projecting porch on each side and a roof of varied heights, a form Liang Sicheng called common in the Tang and Song but lost after the Ming and Qing. The Revolving Sutra Repository hall holds a revolving octagonal bookcase built exactly as the Yingzao Fashi prescribes.
