And pro, the word appears very much in history books. The first appearance was the peace policy that began during the Western Han Dynasty, and it is more famous for the Zhaojun out of the Western Han Dynasty. The so-called peace and affinity is also a measure to maintain the relationship between the two sides. Strangely enough, though, there are many princesses who are kissed. But it is rare to see them having children of their own. Let's see what the reasons are.
The first is that the water and soil are not satisfied, which can be said to be very important. The princess grew up in the palace, even if she was not in the palace, she lived in other good places. If you go to the Mongolian steppe, you will be more or less satisfied. In addition, the eating habits and living environment of the grassland area are different, which is naturally unacceptable to the pampered princess. Therefore, many princesses have been sick since they married into the grassland, which is definitely not conducive to pregnancy. Some even had short lives, and died after a few years on the grasslands.
Secondly, Shan Yu on the grassland, like the emperor of the Central Plains, did not have only one wife. We saw a lot of court dramas, and we knew the emperor's three palaces, six courts, and seventy-two concubines. In the ancient steppe, Shan Yu was the same as the emperor, and both were wives and concubines. Therefore, although the princess is married, if she is not favored alone, she will have no offspring.
Finally, there is the unique way of husband and wife in the grassland. Many of the customs and habits on the grassland are different from those in the Central Plains, and there are obvious differences in the relationship between husband and wife. After the death of a father, the son or brother inherits all of his property, including his own wives and concubines. This was unbearable for the Central Plains Dynasty, the state of etiquette.
It can be said that it is these reasons that many princesses have no heirs although they are close to each other. Of course, there are some, but very few. Sometimes their descendants are not good, after all, they have Han Chinese blood.
