Cultural conflict theorists believe that in today's and future world, the conflict between different cultures and civilizations will intensify, and its prospect is the integration of culture and civilization on the basis of economic integration, which is the unity of world culture. Where will reunification go? Unification to western civilization, specifically to American civilization. This has become the theoretical basis for western countries led by the United States to intervene militarily and politically in other countries. They want to conquer barbarism with so-called civilization, conquer other civilizations with western civilization and realize the global harmony of western civilization. From the process of human civilization, we can easily find that the historical and logical premise of this theory is not established.

Judging from the process of human civilization, all civilizations have gone through a road from closure, collision to conflict, and they are all experiencing the process of communication, integration and unity. In the process of civilization, it seems that there have always been two parallel roads. A road is a clash of civilizations. In the initial stage of civilization, the formation and evolution of various civilizations are relatively independent. Ancient Egyptian civilization, Crete civilization, Two Rivers civilization, China ancient civilization, etc. Are all civilized units independently formed in a relatively isolated state? Shortly thereafter, the collision of civilizations came into being, and a wider range of civilizations appeared from Greece and Rome, the Indian Peninsula to East Asia. Since the era, human civilization has entered the stage of stereotypes and expansion. Western European civilization, Slavic civilization, Arab civilization and Mayan civilization were all formed in this period, and the stereotype of civilization cannot be separated from its expansion. Both stereotyped civilization and formed civilization are accompanied by fierce competition and expansion. With the advent of the capitalist era, the development of various civilizations is becoming more and more unbalanced, and the expansionary and predatory nature of capitalism has directly caused increasingly fierce clash of civilizations. Today, the conflict between civilizations remains the same, and the prospect of future civilization seems to be constant conflict and struggle. This phenomenon is the basic point of the argument of "clash of civilizations".

Another way is the exchange and integration of civilizations. Since the emergence of civilization, the communication between civilizations has always existed, and with the arrival of the conflict era, this communication has been strengthened day by day. So far, the exchange of civilizations has covered all civilizations and all their main contents. Whether it is language, literature, religious beliefs, folk customs, artistic aesthetics, there is always communication and integration. In this exchange and integration, the differences between civilizations are narrowing, their respective characteristics are weakening, and the identity of human civilization is becoming more and more obvious. On the one hand, this is due to the role of cultural annexation and cultural colonization, on the other hand, the openness and compatibility of existing civilized bodies are getting stronger and stronger, and the absorption and accommodation of cultures other than their own has become the nature of most civilized bodies. In this process, the prospect of human civilization should be unitary, which is another basic point of the "clash of civilizations".

We don't need to judge the gains and losses of "clash of civilizations" or "unification of civilizations" from the beginning, because the basic point of their argument is the objective reality in the process of civilization. What we need to see is that with the continuous progress of human civilization, the inevitable result of economic and social development is to maximize the distance between different civilizations and different groups of people, make them interdependent and interdependent, and make people's lifestyles and production methods converge. In the new century or longer, global economic integration and information integration will be realized, and the division between regions and nationalities will be weakened. However, we must also see that the unity of civilization is only the theoretical ultimate direction of the process of human civilization. On the way to this direction, the existence, struggle and even conflict of the diversity of different civilizations is the fundamental driving force for maintaining the progress of human civilization. In this sense, the diversity of civilization is as important to human civilization as the diversity of biology is to the life world. We can also say that the unity of culture is only the ultimate goal and inevitable direction in the history and theoretical process of civilization. When human civilization is exactly the same, that is, when it goes downhill. Therefore, we can say that before reaching this ultimate goal, cultural conflicts and exchanges in the process of human civilization will exist for a long time, and different civilizations will also exist for a long time, which is the driving force and source of the development and progress of human civilization.

As far as cultural conflict and communication are concerned, conflict is an extreme or unconventional communication. The conflict between different civilizations can bring about the extinction of some civilizations, and at the same time, it can also aggravate the progress of some civilizations and even promote the formation of new civilizations. Take Greek and Roman civilization as an example. Without the conflict between Greece and Rome and other civilizations in the Mediterranean region, there would be no glory of these two civilizations, as well as Western European civilization and Islamic civilization. Without barbarians going south and their destruction of Roman civilization, there would be no formation of Western European civilization. Without the Crusades, the vitality of Islamic civilization would not be so strong. The significance of cultural exchange is equally important. Whether a civilization can be dynamic and grow continuously, its openness and the degree of communication with external civilizations are important constraints. The prosperity and civilization of Han and Tang Dynasties, which we are often proud of, is the result of cultural exchange. During the hundreds of years from the Spring and Autumn Period and the Warring States Period to the unification of Qin Dynasty, the blending of core culture and surrounding culture and the communication between Chinese and Western cultures are unprecedented. Wusun, Dayue people and Scots all acted as bridges between China and the West. Through them, the culture, art, bronze technology and agricultural products from the western regions poured in, which provided sufficient preconditions for the rise of Han civilization. Similarly, during the hundreds of years from Wei, Jin, Southern and Northern Dynasties to Tang Dynasty, nomadic peoples in the northwest and northeast continued to go south, and their cultures repeatedly influenced the Central Plains. Buddhism was introduced from the East and quickly communicated with China's philosophy and spiritual world, which provided a guarantee for the rise of Tang civilization. After the establishment of the Tang Dynasty, it adopted an open and gorgeous attitude towards the outside world. No matter the culture of Central Asia, West Asia and Europe, or the culture of Japan, Korea and South Asia, they all came one after another. The Tang Dynasty became the center of the open world, and Chang 'an was an authentic international capital.

Cities have injected a steady stream of vitality into the prosperous Tang civilization.

As far as the existence of different civilizations is concerned, we should first see that different forms of civilization are the products of long-term choice and recognition by different people in different regions, and civilization and culture are a kind of personalized group cognition. "Children are not fish, but they know the joy of fish", which is hard to replace, let alone take over. For example, for Inuit people, what they can accept is the Inuit culture that has been passed down for thousands of years. This kind of culture may be painful for Americans, but equally, American culture may not be happy for many of them. In this sense, we can say that there are only cultural differences, and there is no distinction between good and bad. In the rising tide of human rights in today's world, should the right to civilization also attract enough respect? We should respect the choice of civilized forms by different regions and different groups of people. We should also see that the existence of different civilizations is the prerequisite for the conflict and exchange of civilizations. If there is only one civilization in the world, there will be no conflict and communication. In this sense, no matter the scale or history of civilization, their role in the process of human civilization is irreplaceable. That is, scattered and endangered wild rice is equally important to a huge rice family. Without wild rice, the degradation and extinction of rice will be just around the corner.

Of course, we should also realize that the historical inevitability of the existence of different civilizations and the long-term diversity of civilizations are only a fate that must be faced for the whole process of human civilization and specific forms of civilization. In the conflict of human civilization and the same contradictory movement, any civilization is faced with the choice of life and death. As far as the four ancient civilizations are concerned, Egyptian civilization came to an end in about 2000 BC. At the beginning of the era, Greek civilization disappeared; Shortly thereafter, the unique ancient Indian civilization also withdrew from the historical stage. These lost civilizations are either precipitated as cultural heritage or assimilated by new forms of civilization. After stepping into the forest of modern civilization, the vicissitudes of Chinese civilization are facing unprecedented severe competition and conflict, and the story about the sunken ship and the dead wood remains the same. Where will China's civilization go? Will it become a cultural heritage like ancient Egyptian and ancient Greek civilizations, or will it continue to maintain its endless vitality for thousands of years? Our wish is of course the latter.

In this case, it is the historical responsibility of each of us in China to build a Chinese civilization facing the future and the world. In the construction of new China civilization, the national spirit, national culture and national consciousness that have lasted for thousands of years are solid cornerstones that cannot be abandoned. Only by being rooted in the solid fertile soil of excellent national cultural heritage, absorbing the essence of various civilizations in the world, calmly facing cultural conflicts and actively promoting cultural exchanges, can China's civilization prosper and last forever.
