There were officials in charge of writing history in ancient times. Their task is to pass on what happened in history and let future generations know. In ancient times, wars between countries seemed to be a very common thing. In the past, the social environment was not as good as it is now, and wars often happened. However, according to historical records, most of us were invaded by other countries, but we rarely recorded our aggression against other countries. Is it because we are too weak or the emperor is too timid?

There is nothing wrong with the historical records. It is true that China rarely invades other countries, because we are always recovering our homeland. If a place's land has been ruled by one country for more than 100 years, it is basically the territory of other countries, and it is difficult to get it back. China opened up a very large territory in the Han Dynasty, which has been around two thousand years. The ancient Central Plains Dynasty believed that these were our legitimate territories, and even if they were temporarily occupied by foreign countries, it was certainly not aggression to drive them away.

Secondly, many invaded countries no longer exist, and those small invaded countries have disappeared into the sea of Wang Yang in history. Moreover, there is a saying that "the world is not a king's land", so those occupied lands are regarded as the achievements of the emperor.

Historically, there have been many wars between countries. These countries were vassal states that split in Xia and Shang Dynasties. These forces were all split from our dynasty at the beginning, so when invading, it was not foreign aggression, but civil war.

And because the invasion was so successful, people from other countries were also sinicized into China people, and after time migration, they became one of their own! In fact, there were cases of aggression against other countries in ancient China, but they all successfully spread our thoughts and culture to them and surrendered to our long-standing civilization. Naturally, no one came out against it.

During the Tang Dynasty and the Han Dynasty, many wars of aggression did break out, and this period was also the most frequent time for our external expansion. But those invaded countries have been completely replaced and the whole country no longer exists, so no one can prove that these territories were invaded by us at the beginning.

During the Warring States Period, Qin Chu, Qin, Yan, Zhao, Wei and Han fought and annexed each other, which was not aggression, but unification. Although Emperor Taizong and Li Shimin attacked Korea, the so-called Korea is located in Liaodong Peninsula of our country, and it is also a part of our country, which can only be regarded as recovery!
