If characters are the manifestation of abstract civilization, stone inscription can be seen as the concrete representation of civilization. Longmen Grottoes, the magnificent stone carving complex in ancient China, with its over 100,000 statues stretching along one kilometer, was completed in pieces over 400 years from the Northern Wei Dynasty to the Tang Dynasty until the Northern Song Dynasty. It represents the highest achievement in the art of sculpture, which is a real the treasure in China in terms of religion, fine arts, architecture and calligraphy. 

　　如果字符是抽象文明的表现形式，那么石雕艺术就是有形文明的具体表现。龙门石窟，中国石雕艺术宝库，开凿于北魏孝文帝年间，历经了北魏、隋唐、五代和宋等数朝400余年的沧桑，在长达一公里的峭壁尚，10余万尊佛像栩栩如生。龙门石窟代表了中国古代佛雕艺术的顶峰，是宗教、美术、建筑和书法的宝贵财富。
