In addition to the Northern and Southern Xiangtangshan Caves, there is a third site Shuiyusi, or "Monastery of Ablutions," with caves and images. The site is also popularly called Xiao Xiangtang, or "Little Xiangtang." The West Cave at Shuiyusi is the largest of the carvings at the site and is dated to the Northern Qi period. It is a central pillar cave modeled on the design of the Northern Caves, though much smaller, 5.35 meters wide, 5.5 meters deep and 4.9 meters high. The central pillar has large niches with Buddhist figures carved on three sides and two other large niches on the side walls. Smaller carvings--spirit kings and kneeling monks on the base of the central pillar, rows of donor figures on the font wall, "Thousand Buddhas," flying apsarases and other figures also appear.
