龙山文化
A pottery inscription of the Longshan culture discovered in Dinggong Village, Zouping County, Shandong contains eleven symbols that do not look like the direct ancestor of Chinese characters. Chinese scholar Feng Shi (馮時) argued in 1994 that this inscription can be interpreted as written by the Longshan people. Other scholars, like Ming Ru, are doubtful about attributing a Neolithic date to the inscription. The authenticity of these inscriptions is hotly disputed due to their appearance on a broken ceramic ware, an unusual feature among prehistorical text, as well as its unexpected similar appearance with the Yi script, a modern writing system associated with an ethnic group in the southwestern China, thousands of miles and thousands of years apart from the Longshan culture in northern China.
