Beishan is one of five Dazu Rock Carving sites near the city of Dazu in the Chongqing municipality of China. The main site is Baodangshan and tickets may be bought at either site to visit both. The carvings at Beishan are older (650 AD) than Baodangshan (1200 AD) but Baodangshan is a much larger, much more developed, site --- if you have time to visit two sites then Beishan should be your choice for the second. The day my wife and I were there we were the only visitors (Baodangshan had hundreds on the same day). The carvings are interesting but not as well preserved and many heads have been stolen. I would hope that someday the Chinese government would go from the current protection posture they have at Beishan to really preserving the site and providing more extensive labeling, as they have at Baodangshan.
