Oracle Bone Inscriptions did not record the Xia Dynasty, so how did the Zhou Dynasty know that the Xia Dynasty existed?

Because Zhou people and merchants actually originated from the same civilization, but merchants came to the Yellow River valley first. Later, Zhou people were actually descendants of Harappa civilization. They sailed to the Yellow River valley in China to establish the Shang Dynasty, because they set off earlier and there was no record. Zhou people came from Xinjiang to the upper reaches of the Yellow River through the Silk Road, and their strength was delicate. They first became princes and then killed Yin merchants. This explains why Zhou people left many cultural classics and historical legends, and Mu Xixing, the son of Zhou, visited the Queen Mother of the West. In fact, Zhou people are looking for their ancestors. At the same time, it can also explain why there is no seal cutting culture in Yin merchants, but since the Zhou Dynasty, various seal cutting cultures, imperial seals, official seals and so on have appeared. It is the typical cultural foundation of the highly developed Harappa civilization.
