Damaidi (simplified Chinese: ???; traditional Chinese: ???; pinyin: ; literally: Big wheat field), is the location of 3,172 sets of early Chinese petroglyphs, carved into the cliffs which feature 8,453 individual figures. Cliff carving expert Li Xiangshi stated that "The pictographs are similar to the ancient hieroglyphs of Chinese characters and many can be identified as ancient characters," Another expert said " "Through arduous research, we have found that some pictographs are commonly seen in up to hundreds of pictures in the carvings," said Liu Jingyun, an expert on ancient Oracle Bone characters. The size, shape and meanings of the pictographs in different carvings are the same." These pictographs may be the origin of Chinese characters.
The carvings at Damaidi, which date back 7,000-8,000 years, feature environmental as well as social themes. There are carvings of the sun and moon along with other celestial bodies as well as of people hunting, herding and fighting. Archaeologists believe that some of these symbols (over 1,500) bear a resemblance to ancient hieroglyphs of Chinese characters. If dating estimates of the carvings are correct, this would push back the origins of Chinese writing (previously dated only as far back as the Jiaguwen Oracle Bone inscriptions found at Anyang) from 1200 BC to 6600 BC-6200 BC.
