It is more than 4200 years ago, but the theory of 5000 years of civilization has long existed. With the academic level at that time, it is impossible to make a clear textual research, but we can only roughly explain why China has a history of 5,000 years.
Generally speaking, the history of civilization is marked by cities, bronzes and characters. As far as writing is concerned, Oracle Bone Inscriptions is generally regarded as the oldest writing, and Oracle Bone Inscriptions estimated that it was about 3,000 years ago. 1986, archaeologists discovered bone carving characters of the Yellow Emperor era in Shaanxi, which experts believe is the oldest writing in China.
1979, archaeologists discovered an ancient city and an altar more than 6000 years ago in Chengtoushan site, Hunan province. The civilization degree of Hemudu site about 7000 years ago also strongly proves that the civilization history of China is more than 5000 years.
