The European civilization in the south and west (Mediterranean civilization) inherited the commercial handicraft civilization in Greece and Rome, the nomadic fishing and hunting civilization in northern Europe and eastern Europe, the commercial agricultural civilization in the Middle East and the agricultural civilization in East Asia, so the starting point of civilization is different, so the development direction is also different. Even the indigenous civilization in Black Africa and Oceania, or the Indian civilization in ancient America, has its uniqueness. If you use whoever is advanced and who is backward, the difference is the level of science and technology. In fact, East Asian countries, as agricultural civilizations, are not much better than other countries in science and technology. We have four great inventions. Europe has ancient mathematics, geometry, algebra, chemistry, philosophy, cement, glass and a strong knowledge of astronomy, which China does not have. It is right to be proud of national culture, but at the same time, we should respect the history and culture of nation-states in other regions. We are a member of the world's national forest, and the mountain is by no means the thickest one. Modern times, mainly the discovery of the New World, opened a new chapter in European history. Breaking Asia's control over the East and Arabia's control over the West revived European civilization and profoundly influenced modern society. More than ever, we need to learn advanced knowledge with an open mind, and don't be blind and arrogant. The rejuvenation of the Chinese nation should be based on peaceful coexistence with other ethnic groups, not discrimination against other ethnic groups.
