The so-called international recognition is only a means to attack China, which makes China people doubt themselves and lose confidence.

For Xia and Shang dynasties, the time of writing was very short, but because of the war and time, the possibility of writing was even lower. However, you can't deny yourself just because there is no written record. The addition of characters must be a long process, and then it will be longer until it can form words. China had written records in the Zhou Dynasty. If we push forward, the existence of the Xia Dynasty is normal, even earlier than the Xia Dynasty in the period of Three Emperors and Five Emperors. In addition, the written expressions of Zhou Li and Zhouyi are very mature. Even Oracle Bone Inscriptions is not the official writing of Shang Dynasty, but a folk symbol record. Older hieroglyphics may have existed as early as the Three Emperors and Five Emperors.

Foreign countries often use myths and legends for archaeological inference. Reference is that myths and legends are right, and then textual research is carried out. In the face of China, they took another approach, totally denying China's myth and legend system, thinking that no evidence is false. Why don't those foreigners say that foreign myths and legends are false and only evidence is true? Obviously, it is to formulate two sets of standards.

As for the history of Chinese civilization, the Hemudu culture excavated by archaeology has pushed this history to 7000 years.

Legend has it that China has a history of 7000 years. From summer to modern times, it is 4 100 years. According to historical records, the average life expectancy of the five emperors of Zhuan Xu, Di Ku, Tang Yao, Yu Shun and Yu Xia was above 100 years old. In this way, the cycle of five emperors is about 500 years, that is, 4600 years, and the Huang San period of Fuxi, Shennong and Huangdi is also 5000 years, at least 300 years. However, the inheritance between Huang San is not direct. At that time, the social form was a loose tribal alliance and there was no clear government. Huang San's abdication system is a recommendation system among tribal alliances. Huang San developed into a tribe, and only other tribes were chosen as successors when their own tribe could decline. This can be seen from the dispute between Yan and Huang. If Shennong, who tasted a hundred herbs, was in power, Xuanyuan probably didn't have the courage to challenge his prestige. Therefore, Emperor Yan at that time should be a descendant of Shennong tribe. Accordingly, it is estimated that the alternate development time of each tribe is not less than 500 years, that is, about 1500 years between Huang San, or even longer. If you add the Suiren family who mined wood for fire, the Chao family who built houses and the Juyi family who invented clothes, 7,000 years will be just right.
