Speaking of this issue, in fact, we have to start from the ethnic policy of the Qing Dynasty, and it is interesting to say that the ethnic policy of the Qing Dynasty is completely different from the ethnic policy of the former Yuan Dynasty, and these differences are multi-level differences and many aspects of differences.
What does that mean? That is to say, although they are all the same as the great unification dynasty established by the minority nationalities in the Central Plains, the ethnic policy they adopted has had a completely different effect on their rule, and we say that their ethnic policy in the Qing Dynasty effectively consolidated the rule of their multi-ethnic great unification dynasty, and we are talking about the national policy of the Yuan Dynasty that caused the rapid collapse of their multi-ethnic unification regime.
So, what's the difference? Let's start with the details of the title of the emperor's two daughters with different titles.
After the Yuan Dynasty, as a nomadic people, entered the Central Plains, most of the time pursued an almost substantial ethnic discrimination policy and a narrow national concept of the mongolian Semu people who were almost one-sided, which had a very far-reaching negative impact on his rule, and the Yuan Dynasty people at that time, especially the Yuan Dynasty nobles, always ruled with a very strong sense of discrimination against the original indigenous peoples in the previously conquered areas.
Since the Mongols overthrew the tyranny of the Jin Dynasty, they adopted a policy of genocide and massacre for the Jin dynasty patriarchs and the Jurchens of the Jin Dynasty, that is, the ancestors of the Manchus in the later Qing Dynasty, especially for the Jurchen royal family of the Wanyan clan, the Yuan Rulers almost did not spare a single person's style. This is certainly because of the revenge of the Yuan rulers against the Jurchens, and it also proves from the side that the Yuan dynasty people are not good at managing complex ethnic relations--he also adopted a similar discriminatory and repressive policy against the Han people in the Central Plains.
Compared with it, the Qing Dynasty government attaches great importance to the knowledge of getting along with each other, and he can often find a balance point that can benefit his own nation in the subtle concepts between the various nationalities, this ability is indeed unprecedented, and it is no wonder that the Qing Dynasty was the heyday of the feudal era at the national level, and the skills required for the various feudal eras have long been developed to full maturity.
Here we will talk in detail about the ethnic policy of the Qing Dynasty, although the ethnic policy of the Qing Dynasty also adopted a discriminatory and insulting policy for the Han people, but at his level, it was not so obvious and deliberate, removing a series of tyrannical operations in the early Qing Dynasty, since the middle of the Qing Dynasty, the treatment of the Han nationality has been very gentle, for the Han nationality's green camp army, gradually replaced the Qing Dynasty's own Eight Banners Brigade, this matter also seems to be less concerned, this is actually a kind of progress in ethnic policy. According to what I said above, when the Ancestors of the Jurchens, who later manchurians, were so abused by the Mongols, the Qing Dynasty established by the Manchus gradually stabilized, and adopted a more gentle policy towards the former Mongols, at least compared with the ancestors of the Mongols.
The rulers of the Qing Dynasty paid attention to the marriage relationship with the Mongol tribes as early as before entering the customs, and the emperor Taiji, on the one hand, was the Jurchen leader, on the other hand, he was also the Great Khan of the Mongols, which sounded very incredible, and this was precisely the credit of various marriages before the Qing Dynasty entered the customs. The tradition of marriage between the Qing government and The Mongol tribes dates back to the Nurhaci era, when the Qing government, or later Jin, married the Mongol tribes mainly by marrying the daughter of a Mongol tribal leader, the famous Empress Xiaozhuang, the Mongolian princess who was married that year.
With the Increasing stability of the Qing government's rule in the Central Plains, this tradition was also rare not abandoned, and during the Kangxi Dynasty, in order to entertain the Mongol princes, a summer resort was specially built, and the Qing Dynasty royal family paid great attention to the marriage relationship with the Mongolian royal family, and even in the last years of the Qing Dynasty, it still maintained a considerable number of marriage relations.
Explained so much, it is easy to understand that we will come back again. Back to the title, at that time, the seven princesses and nine princesses of The Ling concubine, the reason why the sister was one level higher than the sister, of course, was because the sister needed to marry far away from Mongolia for marriage, so that since it was a marriage, it was necessary to pay attention to a face, and the diplomacy or marriage between the royal families in East Asia was often like this, paying attention to a door-to-door pair, that is, a pair of acts of giving face to both sides, in fact, this kind of marriage behavior has been established as early as the Han Dynasty - in that year, alloying with the Xiongnu, Isn't it normal that there are often moves to temporarily adopt an ordinary palace maid as a righteous princess.
