Everyone knows that having children was a top priority in ancient times. Confucianism tells us that "no filial piety has three, and no queen is greater", so if you do not have children, then you can be characterized as a great disrespect to your parents.
Especially for the royal families of all dynasties, having children and having boys is the most important, not only related to the inheritance of the bloodline, but also related to the inheritance of the throne, some concubines have spent their lives wanting to give birth to the emperor's dragon son, so they will not hesitate to endure several birth pains in exchange for the final cultivation results.
However, there are also emperors who have never had heirs, such as Zhu Houzhao of the Ming Dynasty, and then the throne was directly given to his cousin Zhu Houxi, which did not fall into the hands of outsiders, but due to the clamping down on Confucianism, Zhu Houzhao also carried a lot of ideological pressure. But there are also some other ethnic groups other than the Han chinese, because they have not been educated by Confucianism, and they have a completely different view on the matter of having children.
For example, the Huns were a people. In history, shortly after the establishment of the Han Dynasty, in order to calm the unstable factors in the border area, Liu Bang had sent a large number of troops to the frontier, but he was beaten by the Xiongnu, and Liu Bang almost lost his life. After that, Liu Bang thought bitterly and felt that fighting was not the solution to the problem, so he came up with another clever way to solve the border problem.
This clever plan is to send the princess to the Xiongnu tribe and relatives, which is also the beginning of the princess and relatives in Chinese history. The two countries exchanged princes as hostages during the Warring States period, and the two countries could maintain a relatively stable relationship between the two countries, and it was difficult to see each other again. In addition, if the princess gave birth to a child and inherited the leader of the Xiongnu in the future, because the mother was expensive, she would not attack the Han Dynasty.
But Liu Bang did not expect that although the Xiongnu were a barbarian, they still had to be shrewd in thinking about problems. Those princesses who kissed the past will not give birth to any children for them. For political purposes, the princesses sent out by Liu Bang to be close to each other must be very beautiful, they may not even be Liu Bang's daughters, they can also select beautiful women from the people to be crowned princesses, and then send them to the peace relatives.
After these princesses came to the northern Xiongnu tribes with great hardship, due to the huge differences in geographical environment and climate, it was easy to be dissatisfied with the water and soil, plus the physique of the ancients was far inferior to that of modern people, not to mention the princesses who had been pampered since childhood.
For a long time, these princesses who were close to each other were all "Lin Daiyu" appearances, sick, and some even lost their fertility. And this kind of simply can not get the favor of Shan Yu, they at most see these princesses as booty, not companions for life.
In addition, the princesses who sent past and kissed were generally quite young. Coupled with the language barrier, they generally have a hard time coping with the intrigues of the women in the tribe, and the ascension to the throne is a rather difficult thing, the harem can't fight, and shan Yu has children.
Moreover, there is also the custom of inheriting the previous generation of Shan Yu's wife. For example, if the younger brother succeeds the older brother as the new Shan Yu, his sister-in-law must also pass on, or Shan Yu Xinna's concubines can also eat and live with Shan Yu's son, they do not have such a concept of ethical order as the Han. Under this custom, most of the princesses who are close to them will not tolerate complicity, and a large part of them will choose to commit suicide to maintain their virginity, not to mention giving birth to children.
Therefore, Liu Bang, the leader who wanted to assimilate the Xiongnu with the pro-plan, basically did not play any role. On the contrary, they suffered so many princesses, they became victims of politics, wasted their great youth like flowers and jade, and due to the various strange customs of the Xiongnu and the snub of Shan Yu, they could not give birth to their own children, and finally died alone in a foreign land, which can be described as lamentable.
