What are the carving methods of stone carving?

Stone carving refers to the use of various carved and carved stones to create a visible and tangible artistic image with a certain space to reflect social life and express the artist's aesthetic feelings, feelings and ideals. Commonly used stones are granite, marble, bluestone and sandstone. Stone is hard and weathering-resistant, and it is the main material for large-scale commemorative sculptures. Stone carving and rock painting, in the border areas with suitable conditions, are still the main forms of original artists' creation, enduring for a long time. For example, there are many Neolithic works in Yinshan rock paintings. The expression style of Yinshan rock paintings has far-reaching influence. In fact, most of the rock paintings created by ancient nomadic people in northern and northwestern China are stone carvings, and their source should be traced back to Yinshan rock paintings. In addition, hunting and animal description will always be eternal themes. The pictographs of inscriptions on bronze in Shang and Zhou Dynasties, the realistic patterns of bronzes in Warring States and the hunting pictures of figures in portrait bricks in Qin Dynasty are all extensions of this technique, but the latter is more and more accurate, formal and rhythmic. It can be seen that the abstract generalization and exaggeration of shadow play techniques can best reflect the aesthetic ideal of China's classical art, which does not emphasize modeling, but pursues vivid charm. In addition, another source of China ancient stone carving technology-line carving, also appeared in the Neolithic Age. The stone statue found in Jiangjun Cliff in Lianyungang, Jiangsu Province is believed to have been carved by primitive ancestors at the end of Neolithic Age. This form of line carving stone carving is the most widely used in stone carving creation in past dynasties. Although there are not many stone carvings unearthed in the Neolithic Age, the style is not simple, which is completely different from stone carvings and rock paintings. Several talc sculptures in Houwa, Donggou, Liaoning, are all round figures, with rough and strange knife techniques and simple and vivid images, which shows that they are symbolic works.
