There are many domineering words in ancient China, but there are not many domineering words that can be called arrogant, for example, a sentence that appeared in the Qin and Han Dynasties makes modern people unable to understand, this passage is like this: "Where the sun and the moon shine, the rivers are all Han soil." In modern times, this sentence is indeed a bit overconfident, and even full of arrogance, because before the Qin and Han Dynasties, there were several powerful empires in the world, such as: Assyrian Empire, Persian Empire, Alexander Empire, Peacock Empire, Seleucid Empire, etc., all earlier than the Qin Dynasty. At the same time as the Qin and Han Dynasties, there were still the Roman Empire, the Sabbath Empire and the Kushan Empire in the world, and the strength of these empires could be on par with the Qin and Han Dynasties.
From the perspective of world geography, the eastern part of China is an endless ocean, and ancient people were in awe of water, and generally did not take the initiative to live in areas rich in water resources. The south is close to the equator, the climate is hot and rainfall is very high, the vegetation is dense and produces a toxic miasma, and no one wants to go here. To the north is the very cold Siberian plateau, which in ancient times belonged to the extremely cold land. The ancients believed that these places were all areas set up by heaven to punish bad people. Some also say that the north is a vast expanse. Not to mention China, even when Alexander hit the Pamir Plateau, he eventually thought it was the far east of the world and never hit the east again. At that time, who knew that there was a world called by the ancients in the east? The reason why the ancient rulers said that sentence was still limited by the environment at that time, and they could only travel to such a small place in the world. It's like we now know that the whole world was so big.
The East and the West were cut apart because of this continuous series of mountains and mountains, and the "exchange (exchange of force and cultural exchange) between China and the West" could not be carried out at that time, and even Alexander once thought that he was the strongest in the world, because he did not know that there was a powerful dynasty in the East. On the other hand, the Central Plains Dynasty did not know that there were other forces in the West at that time, and in the circle of the ancients themselves, there was no one around to fight, and there were still some places that were not civilized, or the state of primitive society. Under the limitations of the territory, the Central Plains Dynasty fought all over the invincible hands of the "world", and naturally had the courage to say that "all the sun and the moon shine, and the rivers and rivers are all Han soil." This is not arrogance, nor ignorance, nor superficiality, but a kind of pride and pride of the ancients in their powerful and advanced civilization.
