The territory of the mainland from ancient times to the present is very vast, so there are more ethnic groups living on it, and even now it is the same, although it has always been said that there are fifty-six nationalities, in fact, it should be more, because some ethnic groups are too small to be counted, and this is the case with the nation we are talking about today, and their registration has only begun in recent years.
At the end of the Yuan Dynasty, the south was controlled by the Han rebels, and the Yuan Dynasty forces could only move in the north, originally thinking that these rebel armies would soon go north, but strangely, they stopped the pace of crusades and chose to fight with each other, among them was Zhu Yuanzhang, who stood out among these forces, quickly eliminated Chen Youyi, fixed the capital in Nanjing, and then found someone to go north to drive the Mongols away. By this time, basically most of the territory has been unified, but there are still some corners and corners that are not controlled, such as Yunnan, the Yuan Dynasty period here is the territory of the King of Liang, after years of development, the power here is getting stronger and stronger, the King of Liang itself inherited the warlike character of the ancestors, so the people here are also a temper, the Ming Dynasty brought people to contact and hope to be able to solve the peaceful solution is useless, can only use force to decide the victory or defeat.
However, in 1381, Zhu Yuanzhang thought of a good way, let Lantian and others stationed in Yunnan with 300,000 troops, simply live there for a long time, and combine with the locals, how many years the Ming Dynasty existed, they were there for many years, so from this point of view, they themselves were Han. Until the establishment of the Qing Dynasty, the qing army at that time returned to its hometown with more than 100,000 horses and horses under the banner of restoring the Ming Dynasty, but at that time, the overall situation was decided, and such a small group of people really could not change the fate of the Ming Dynasty, so after a lot of fighting, they only had a few thousand people left from more than 100,000 people, and there was no way but to return to Yunnan, and since then they have changed their names and surnames and lived a peaceful life.
They have always followed the customs of the Ming Dynasty, so they are somewhat different from the habits of the surrounding areas or other ethnic groups, in fact, they are Han Chinese, but they have fallen behind in the process of development, after hundreds of years of reproduction, their population has returned to hundreds of thousands, and because of the different customs, they have also slowly developed into unique wearing green people, but wearing green people have not been recognized as ethnic minorities, as the society is more and more civilized, more respectful of history, the wearing green people have finally been recognized by the state, And these people who wear green can also have the identity that originally belonged to them.
Now that the identity cards of these people have been revoked from their Han identities, they can write that the ethnic group is a qing people, and they are the descendants of those warriors who have been defending Yunnan for the Ming Dynasty.
