Why is China the only one of the four ancient civilizations still alive?

First of all, the competition has not changed. China has always been dominated by Han people, such as ancient Egypt. The main residents are North African aborigines, but they were occupied by Alexandria, Persia and Rome for hundreds of years. Now the main race is Arabs. The same is true of India. Today's Indians are mostly Aryan immigrants, not ancient India, and the two river basins are mixed. Thousands of years ago, the race was completely different from now.

Secondly, China's Oracle characters can be read, and the evolution of characters between dynasties has always been inherited. But other cuneiform characters in the two river basins, hieroglyphics in ancient Egypt and Indian characters are unknown, and people there can't understand them now, which is different from the local language. For example, hieroglyphics in ancient Egypt were later deciphered by western archaeologists, while modern Egyptians all speak Arabic. China is still a Chinese character. He can read it himself, and he is of the same ancestry.
