Writing is a tool that people use to record language symbols and exchange ideas. In the past, people thought that Oracle Bone Inscriptions in Shang Dynasty was the earliest written language in China.
After 1977, archaeologists excavated the ruins of two small towns in the east and west in the ruins of Xia Dynasty about15km southeast of Wang Chenggang, Dengfeng County, Henan Province, and found some precious written materials of Xia Dynasty. For example, in an ash pit at the site of Xicheng. A muddy black pottery flat bottom was found in early summer, and the word ""was found at the bottom of the flat bottom before the pottery was fired. The word consists of two parts, just like holding it with two hands. It may be "* *", which probably represents the surname of the owner of the pottery. Far from being a symbol, this word transcends the hieroglyphic stage, but is a knowing word, so it is a real word. This discovery strongly proves that as early as 4,000 years ago, China had written characters in the early Xia Dynasty.
