What is the root of China's enduring culture (200~300 words)?

Among the four ancient civilizations in the world, ancient Egyptian civilization, ancient Greek civilization and ancient Indian civilization were ruthlessly destroyed by external forces in the course of historical development, but China's ancient civilization has never been broken. Why is this? Where is the mystery? Professor Li Shaolian's new book "The Civilization Never Lost —— A Study of the Ancient Culture in the Central Plains" has made a useful exploration on this issue from the perspective of the rich resources and development process of the ancient culture in the Central Plains.

He believes that there are eight main factors contributing to the prosperity of Chinese civilization: first, it has a vast territory, rich resources and strong strength; Second, China's traditional culture has a strong power to melt foreign culture; Third, a strong national subject strengthens the foundation of the country; Fourthly, the Confucian thought of governing the country and keeping the country safe has profound humanistic charm; Fifth, the tenacious resilience of the Chinese nation; Sixth, the Central Plains civilization has always been ahead of the surrounding civilizations; Seventh, the patriotic tradition of the Chinese nation; Eighth, always adhere to the cultural attitude of making foreign things serve China and developing independently.

Geographically, there are seas in the east and south of China, and the Qinghai-Tibet Plateau, the highest plateau in the world, is located in the southwest. Other foreigners can't invade, only the threat from the north, but all the nomadic people in the north can't replace the advanced Chinese agricultural civilization, and finally they are assimilated by Chinese civilization.

Many aspects can be discussed. I suggest looking for them from the school library to deepen my impression.
