Ever since Bo Yi rejected Dayu's Zen concessions and instead allowed Dayu's son Xia Qi to inherit the throne, the throne of ancient Chinese society had formed a "family world" succession system.
After that, the way the throne was changed was inherited by his own sons, and without sons, he was inherited by his brothers.
However, in this process, there will also be many problems. There have been many "little emperors" in Chinese history, most of whom were very young when they succeeded to the throne, and some of them were even pushed to the throne in their infancy, but what does a baby know about governing the country? He even needed someone to change his diapers.
Therefore, in order to make the throne pass smoothly, the ancients would choose a method to "entrust the orphan", which means to entrust the little emperor to someone he trusts, and then control the government on his behalf before he grows up, and then transfer the power to him after the little emperor can be independent.
There have been several successful entrustments in history, such as the Han Wu Emperor Huo Guang, although most of the later generations mentioned Huo Guang as a "powerful minister", but no one thought that he was a traitor, he did break his heart for the Han Dynasty's modest karma, and he did not deviate from the beginning to the end.
Even if Liu Yi had later destroyed huo jiamanmen, he did not deprive Huo Guang of his merits, but placed him in the first place of the Qilin Pavilion heroes, and it could be seen that Huo Guang really contributed to the Great Han.
Similarly, Liu Beituo's lone Zhuge Liang is also a good story in history.
However, the power of this thing is easy to corrupt people, once the power is mastered, it is difficult to hand him over, there are many examples of failure in history, when the Song Wu Emperor Liu Yu's orphan was a failed orphan, he handed over his government to the four ministers he trusted most during his lifetime, but who knew that his front foot just died, these 4 orphan ministers killed the little emperor.
Liu Yu was born in 363 AD, and like Liu Bei, he was a relative of the Han Dynasty, and his ancestor was Liu Bang's younger brother Liu Jiao.
However, due to emperor Wu of the Han Dynasty's "Tui En Order", Liu Yu's identity had long been useless during the Southern and Northern Dynasties, and Liu Yu was also like Liu Bei in his early years, a mat weaver and a peddler, and had no plan for life.
Until Liu Yu once sold shoes on the street as usual, he inadvertently saw General Xie Xuan who had returned from victory, and looked at Xie Xuan's majestic appearance, Liu Yu sighed that the eldest husband should be like this.
So in these few years he decided to join the army, and in the army, he finally became the emperor from a small soldier in the southern conquest and northern war for decades.
Liu Yu's political and military forces were almost unmatched at that time, Liu Yu reigned for one day, Northern Wei did not dare to go south after all, Liu Yu was in Chang'an, Helian Bobo did not dare to covet Chang'an.
In 420, Liu Yu overthrew the rule of the Sima family and ascended the throne as emperor, known in history as Emperor Wu of Song.
After ascending the throne, Liu Yuli was very frugal and frugal, and thus won the support of his subjects.
However, Liu Yu has a very headache problem, he does not have a qualified son, Liu Yu can be said to be "old and have children", before the age of 40 Liu Yu did not have a son, until later after the success of fame there were several sons.
At that time, Liu Yu was nearly 60 years old, and his son was only 16 years old, and this person was greedy and had no ability to govern the country at all.
In order to pass on the Jiangshan lineage, Liu Yu specially found him four auxiliary ministers before his death, these four were Liu Yu's confidants: Xie Han, Tan Daoji, Xu Xianzhi and Fu Liang.
Among them, Tan Daoji was born in the same cold door as Liu Yu, starting from a small soldier to become a commander of the party, Xie Han was the representative of the door valve, born from the Xie clan of Chen County, and Xu Xianzhi and Fu Liang were from the middle class.
Liu Yu's arrangement for orphanage before his death was obvious, and he wanted to let the four orphan ministers assist Liu Yifu well.
However, he was also worried that the four orphan ministers had too much power, so they arranged them separately, and it could be seen that Liu Yu's orphan arrangement was clear and clear, and these four people represented different forces and also represented their own interest classes, and would not let them have the opportunity to collude with each other.
Liu Yu did take all aspects into account, but the only one who did not take it into account was his son Liu Yifu.
After he ascended the throne, he had a lot of fun and bad work, and he only knew how to play all day long, and the repeated advice of several ministers failed to work, and even threatened to kill them.
And Xu Xianzhi, Fu Liang, and Xie Han stood together in this matter, in order to protect themselves, they had to start first, and then they let Tan Daoji get on their thief ship.
In 424, two years after Liu Yu's death, four ministers led troops into Liu Yifu's palace to force him to hand over the jade seal, and after that, Liu Yifu's third brother Liu Yilong succeeded him.
Liu Yilong was supported by Xu Xianzhi and others, but for the emperor, at this time, the rights of the powerful subjects even exceeded him, so wouldn't he be like a needle in a haystack?
Therefore, the behavior of Xu Xianzhi and others caused suspicion, and after Liu Yilong successfully controlled the government, he began to gradually liquidate the four trusted ministers, and eventually these four ministers all died at the hands of Liu Yilong.
