There are many reasons why the West did not recognize the Xia Dynasty in China. There are no words, no written history, too many related myths, and no buildings left. It seems reasonable, but in fact there are hidden contradictions.
What contradiction? The contradiction of double standards, westerners' own civilizations such as Troy and Messini are also full of evidence and myths. However, they are tolerant of the lack of evidence of these civilizations, and they are confident and even boastful. However, the civilization of China and even East Asian countries is really harsh and haggle over every ounce.
So, what will happen if we measure summer by the standards of other civilizations?
The only one who has the confidence to stand the test is Egypt. There is no way. The construction industry in Upper Egypt is indeed far ahead, and the magnificent pyramids are ironclad proof.
But Egypt doesn't have to worry about being censored at all, because Upper Egypt has long been extinct, and Rome's conquest of the Nile Valley has also brought Egypt into the western cultural circle, and Egypt is one of our own.
Other countries in East Asia can be sure that the civilization was born later than China, and the civilization in America has declined, so it is natural to go back to the "compassionate" western scholars and decorate their experiences with the research results there. In sub-Saharan Africa, there is almost no need to study history. Until white people immigrated with guns, it was naturally tribal times.
Therefore, China is the only country that really needs to prove itself. Only the Chinese nation has a history of more than 5,000 years, but it is not a western cultural circle.
Before a large number of bronze dings were unearthed and Yin ruins were excavated, the West did not recognize the existence of Shang. The same is true in summer, which must be searched by our own archaeologists.
