After Qin destroyed six countries, a small country survived. Why didn't Qin Shihuang destroy it?

Qin Shihuang unified the world, but he did not destroy all the countries, leaving the country behind. I believe many people can't understand why they left this country alone and left their great cause of reunification flawed.

Defending the country was very special in the Spring and Autumn Period. Although it belonged to the Zhou Dynasty, it inherited the Shang Dynasty in culture. The reason for this is mainly because defending the country and defending the country is based on the homeland of the Shang Dynasty, and there are many adherents of the Shang Dynasty.

As a country in the hinterland of the Central Plains, Weiguo was once strong, but gradually weakened with successive blows. During the Warring States period, defending the country seems to be gone, because countries such as Wei and South Korea have covered it up.

When Wei got up, he felt that there was no need to defend his country, so he sent his troops out directly. This kind of extinction is not nothing left, but the inheritance of the throne of Weiguo.

In this way, although Wei has a king, it does not exist independently, but is a vassal state of Wei. In fact, this kind of thing is very common in the Spring and Autumn Period and the Warring States Period. Give the former king a fief and let him live in peace.

The king of a country and the king of a country are not the same thing, just one level apart.

Generally speaking, after Wei was destroyed by Wei, Wei was considered to exist in name only.

Later, as Wei was destroyed by Qin, Wei was in the hands of Qin. Qin Shihuang didn't care too much about this country in name only.

Qin Shihuang still retained the title of the monarch of Wei, which was a means of his rule and sent some people from Qin to Wei, so that they would not pose a threat to Qin. Once there is no threat, there is naturally no need to destroy Wei.

Qin Shihuang paid great attention to influence. After he succeeded to the throne, he thought of many ways to strengthen his authority, including wooing many Confucian scholars to work for him. Among these wooing people, mainly including the old nobles of Wei, all originated in Zhou. The way to win them over is to give them status and make them feel satisfied.

Between countries, there are many situations similar to defending the country and sealing the monarch. These people are very strong, and some can completely compete with the government. We can't completely destroy them, we can only take them in and get their support, so that the state can manage some areas conveniently. After Qin Ershi came to power, he abolished the title of monarch, which led to many resistance forces.

In addition, Guo Wei had a great influence on Qin. Shang Yang came from Guo Wei and Lv Buwei also came from Guo Wei, which enabled Qin to develop. There are many talents who defend the country, and most of them work in other countries. It is precisely because of this that the country was indirectly retained. Defending the country and defending the country, it is harmless to have more talents, which is beneficial to other countries.

Without the support of these talents, defending the country and defending the country may have been destroyed long ago, and there is no value in existence. Wei rarely chooses to expand its territory. After Qin unified the six countries, Wei did not attract the attention of Qin. In contrast, the threat of defending Qin is not worth mentioning at all, and it is beneficial and harmless.
