In Chinese history, emperors rarely had no heirs, because there was never a shortage of women in the imperial palace. Generally speaking, emperors without sons and heirs were due to their physical problems. This was very unfavorable to the imperial court, and it was easy to cause national turmoil, and the emperor himself would have pressure. Whether it is filial piety or the stability of the dynasty, if the emperor without a son is not accepted by the world, and there has been such a person in history, because he cannot have children, he can only think of a way to do it ingenuity.
Liu Ziye was the bloodline of Emperor Xiaowu. After emperor Xiaowu's death, Liu Ziye succeeded to the throne. However, the new emperor not only lacked the political and political capacity of the dynasty. Not only did he often kill people for no reason, so for a long time all the ministers in the courtroom panicked and feared that he would be killed in the future. Liu Yu and Liu Ziye are uncles and nephews. Liu Yu was worried that Liu Ziye would kill himself. He led the rebellion. Liu Yu then became Emperor Ming of Song. In fact, because of what he did, he was also wary of his own people. In order to keep his throne, Emperor Ming of Song killed almost all his tongzong.
Although Liu Biao was not worried about usurping power at this time, he found that he could not have a son, which was a serious problem. In the future, no heir will easily lose the throne. At this moment, Emperor Ming of Song saw a handsome and talented minister, Li Dao'er. When Liu Biao was worried about his heir, he suddenly came up with an idea. Emperor Ming of Song inquired about Li Dao'er's family and learned that Li Dao'er had ten sons. Liu Yu decided to give Li Dao'er a concubine, and Chen Miaodeng was also given to Li Dao'er by Emperor Xiaowu. If it were not for the future heir, he would not be willing to reward Chen Miaodeng to Li Dao'er.
Of course, Liu Yu gave his concubine to the chancellor for no reason. His main purpose was to get Chen Miaodeng to conceive Li Dao'er's son. He chose Li Dao'er because he knew his fertility and good looks. For Liu Yu, this was also the perfect strategy at that time. Liu Yu also told Chen Miaodeng if she had one in the future. Pregnant, this son is the future heir. Later, Chen Miaodeng soon became pregnant. Liu Yu took her back to the palace. Chen Miaodeng was born to the later emperor Liu Yu. Although Liu Yu was ridiculous enough, he found an heir anyway.
