What are the decorative arts of Neolithic rock paintings?

Primitive petroglyphs are drawings carved or painted on rocks with high aesthetic value. Hundreds of rock painting sites have been found in China, such as the Huashan rock paintings in Guangxi, the Cangyuan rock paintings in Yunnan, the Black Mountain rock paintings in Gansu, the Yinshan rock paintings in Inner Mongolia, and the General Cliff rock paintings in Lianyungang, Jiangsu Province. Themes include characters, animals, sun, moon and stars, houses, weapons, gods, symbols, hand and foot prints, human faces, vehicles, tents, etc., reflecting the content of hunting, war, dance, rituals, and fertility worship.
