First of all, there is no doubt that the Xia Dynasty was the first dynasty in China. The sources of evidence for the existence of Xia Dynasty are mainly theoretical evidence and archaeological remains. Secondly, before the Xia Dynasty, in ancient China, many tribes lived together, and then everyone elected the most talented person as the supreme leader of each tribe.

Let's start with the theoretical evidence that the Xia Dynasty was the first dynasty in ancient China. In ancient China, the records about the existence of Xia Dynasty mainly came from historical books and chronicles of bamboo books. Of course, there are descriptions of the Xia Dynasty in Zuozhuan and Zhouyi. In particular, Historical Records written by Sima Qian is a powerful supporting material for China historians and archaeologists to study the ancient history of China.

Therefore, there is no doubt about its existence in the Xia Dynasty, which is recorded in Historical Records compiled by Sima Qian. Only in recent years, many scholars at home and abroad think that the theoretical support alone is not enough to prove that the Xia Dynasty is a real dynasty, so there has been a debate about whether the Xia Dynasty really exists.

Let's talk about the archaeological remains discovered in the Xia Dynasty. Although there are records of the Xia Dynasty in many historical books in ancient China, there is no clear evidence that a relic was produced in the Xia Dynasty as far as archaeological remains are concerned. But discovered in recent years? Erlitou? The site has become a strong evidence to prove the existence of the Xia Dynasty.

The establishment of the Xia Dynasty also marked the beginning of the slave society in ancient China. The election method of the country's top leaders changed from * * * to a family heirloom, that is to say, the country at this time changed from * * * to private ownership. Before the Xia Dynasty, there was no obvious hierarchy between people, but after the establishment of the Xia Dynasty, some people were inferior to others or even inferior to others in all aspects for various reasons.

So I think the establishment of Xia Dynasty made people's happiness weaker, or the former tribal system was better.
