What is recorded is history, so are there any unrecorded dynasties in history?

As the first dynasty in the history of China, there are many beautiful legends in the Xia Dynasty, such as Dayu's flood control, the demise of Yao and Shun, and some more mythical historical stories. Therefore, there are few records about the Xia Dynasty in real historical materials. Some people haven't heard of the story of Xia Dynasty in Oracle Bone Inscriptions in the shopping mall. Oracle Bone Inscriptions can record some things.

For example, the sacrificial war, the hydrology of Tianhou, and even the harvest of agriculture were all recorded by relevant parties. In Oracle Bone Inscriptions of Shang Dynasty, we didn't find the word Xia Dynasty, even Xia Dynasty was invented by Zhou Dynasty. If Shang Tang destroyed the Xia Dynasty and the Shang Dynasty defeated the fatuous Xia Dynasty, he would definitely belittle the Xia Dynasty and even make its reputation go down in history.

Second,? Three tribes

Xia, Shang and Western Zhou Dynasties are three dynasties in history, and even in the eyes of China historians, they are all folk dynasties. In fact, they are not three related dynasties, but three different tribes. In other words, in China at that time, Xia, Shang and Wednesday tribes all existed at the same time.

Third,? Zhou dynasty

According to historical records, people in the Zhou Dynasty have indeed recorded all historical events and passed them down to this day. The existence of Xia Dynasty and Shang Dynasty is really not high, because these two dynasties are only two tribes, so assuming that Xia Dynasty does not exist, Xia tribe does exist.

After the mall defeated the lower tribe, in order to uproot the grass, all the people in the lower army were killed and all the historical records at that time were destroyed. It is easy for a coercive dynasty to do such a thing, so the history of Xia Dynasty is not surprising.
