There is no convincing basis, but the judgment conclusion made by foreign scholars based on the lack of writing system in Xia civilization. The existence of Xia civilization in China is controversial in the west, because no mature writing system has been found, but this is a far-fetched reason. Indians have no writing, and they are also recognized civilizations. The imprint of human life in an era is undeniable. Sanxingdui site, Erlitou site, all kinds of pottery pots and bronzes unearthed in China can be regarded as the existence of Xia Dynasty. Moreover, the Erlitou site reached 3 million square meters, and only 40,000 square meters were excavated in cash, which is just the tip of the iceberg.

Foreign scholars believe that it is unscientific to judge a palace when you see a large rammer. The palace in Erlitou has only a separate space in the front hall, not a space where officials can be served, which does not conform to the description of the court in the Western Zhou Dynasty, and is more like a religious temple. At this point, many people began to doubt whether the large buildings in Erlitou site were palaces. Of course, if we can find the word "Xia" in Erlitou, then all the puzzles will be solved. Foreigners may not be familiar with China's ancient books, so it is more difficult to master them and relatively easy to be biased. They only believe in archaeological evidence, but there were not enough archaeological achievements in China at that time to confirm it, so it is not surprising to draw such a conclusion. I believe that in the near future, with the progress of archaeological technology, many unresolved disputes will be solved.

Many people will think that the questioning of China's ancient history is due to the double standards and unwarranted accusations abroad, coupled with the incompetence of domestic experts. In fact, westerners really question the ancient history of China and don't want to raise the upper limit of China's history easily. However, with the increasing scale of our archaeology, our country's voice in history is getting heavier and heavier, but they rely on our archaeological data. In fact, the people who really questioned the existence of the Xia Dynasty are all at home, and experts and scholars have different opinions, which makes us at a loss. Even we are not confident ourselves, foreigners determine the existence of the dynasty according to the standards of city-state and metal writing, let alone admit the existence of the Xia Dynasty.

And we didn't have modern archaeology when we questioned it. What we lack is not physical evidence or symbols, but explanations. There are very few things left in the Xia Dynasty, and the scale of architecture at that time was very different from that now. Maybe the court at that time was only the size of the present house. Therefore, the study of Xia Dynasty can only find evidence from legends. Writing and metal are important criteria for historians to judge whether an ancient historical country belongs to civilization or culture, so they can only expect updated archaeological achievements to be released.
