As the end of the king of the subjugated country, generally speaking, it is very miserable, even if you meet some more enlightened emperors, when dealing with the former imperial family, you will do a more desperate job, and even uproot it, completely exempt from future troubles.
Of course, it is not excluded that some fallen kings have received preferential treatment from the enemy after the fall of the dynasty or the country, which is also normal.

Liu Chan, the lord of the Shu Han Dynasty, was treated very well after the Shu Han regime was attacked by Cao Wei, and not only did not suffer the disaster of killing, but ended up at ease.
After Sima Yi's family took power over Cao Wei, Sima Zhao was persuaded to kill Liu Chan, but Sima Zhao repeatedly disagreed.
Qunchen was puzzled, and Sima Zhao took out the three words that Liu Chan had written after surrendering, and let everyone read them backwards, and after reading them, everyone unconsciously inhaled a cold breath.
Liu Chan, the lord of the Shu Han Dynasty
Liu Chan was born in 207 AD by Liu Bei, the founding emperor of the Shu Han Dynasty, and his concubine Lady Mu Gan, liu Bei was naturally very happy to have a son in middle age.
However, at this time, Liu Bei was in the ascending period of his career, and it was in this year that Liu Bei ushered in one of the most important courtiers in his life, invited Zhuge Liang through the Three Gu Maolu, and through Longzhong, liu Bei's future had a very clear direction.
Liu Bei, with the help of Zhuge Liang, was strong and strong, and soon became jealous of Cao Cao, who had just unified the north, and personally led an army of 100,000 to the south.
After Liu Bei heard about it, he had to take his army and ordinary people to leave Xinye, which he had painstakingly operated for eight years.
In the face of Cao Cao's step by step, Liu Bei fled all the way west, and finally was chased by Cao Cao at Jiangling, with heavy losses, had to abandon his wife and children, and led more than ten people to flee in a hurry, if it were not for Zhao Yun's divine help, I am afraid that this battle would have caused Liu Chan to lose his life.
After the Battle of Chibi, Liu Bei gained a foothold in Jingzhou, and immediately marched to Xichuan, began to implement longzhong's strategy of dividing the world into three parts, and soon occupied Sichuan and other places, and then won the Battle of Hanzhong, at this time Shu Han reached its peak period.
At this time, Liu Chan was still young, and under the care of his stepmother Sun Shangxiang, he spent a happy and happy childhood in Jingzhou.
However, when he was five years old, Lady Sun never returned, and Liu Chan, who had lost the protection of his stepmother, could only grow up under the care of his uncle, which had a very important relationship with his subsequent personality formation.
After Liu Chan became crown prince, Liu Bei began to focus on cultivating his own successor, and he asked Liu Chan to worship Zhuge Liang and Yi Yuan as teachers, study shenzi, han feizi, guanzi, liutao, zuochuan and other books, and also learn riding and shooting.
From here, it can be seen that Liu Bei used a lot of painstaking efforts on Liu Chan, for the sake of his own Jiangshan Sheji, in order to be able to "restore the Han Room", Liu Bei can be described as a good intention.
With The death of Liu Bei in the White Emperor's City, Liu Chan succeeded to the throne and became the supreme ruler of the Shu Han Dynasty, trusting Zhuge Liang and other old ministers, and once equal to the Cao Wei clique, and was also a Ming Emperor
After Zhuge Liang's death, Liu Chan, who lacked supervision and restraint, began to release himself, appointing eunuchs such as Huang Hao and squeezing out Jiang Wei and other able subjects, and was eventually captured by the Cao Wei clique in one fell swoop, becoming a prisoner of Cao Wei.
A good life after being captured
After the surrender, Liu Chan was escorted by the army to Luoyang, where he received good preferential treatment and was given the title of Duke of Anle County.
In the fiefdom of Anle County, Liu Chan lived a comfortable life, and I am afraid that Liu Chan learned from his distant cousin Liu Xie of Han.
Liu Xie lived peacefully and happily in his fiefdom of Shanyang and lived a pastoral life of poetry and painting, not only did he manage Shanyang in an orderly manner and become a pure land during the War and Chaos of the Three Kingdoms, but also received the care of Cao Wei, who was able to establish a temple in his fiefdom and enshrine his ancestors.
Although Liu Chan's life in peace was completely inferior to that of Liu Xie, it was definitely better than the vast majority of ordinary people at that time, because Liu Chan had the idea of "enjoying here, not thinking about Shu".
Such a happy day, even in the peak period of the Cao Wei clique and the Sima clan's struggle for power and profit, there was still no abnormality, just as the so-called "see all the prosperity of the world, three thousand floating like water." ”
The last emperor who died well
After Sima Shi completely seized the power of Cao Wei, many people were slaughtered, especially Cao Shuang, the powerful minister at that time, who was exterminated by the three tribes, and it was extremely miserable.
Perhaps because of the killing of too many people, Sima Zhao and his men were panicked about any potential opponents, and even Liu Chan, the emperor of the Shu Han Dynasty, who had been destroyed for many years, had a jealous heart.
This kind of thief's heart made Sima Zhao and others sit on a needle and feel, always thinking about how to eliminate the so-called hostile forces.
Liu Chan was in danger because of the villains of Sima Zhao and others, but Liu Chan easily defused Sima Zhao's hostility with only one move and turned the crisis into safety.
Liu Chan ordered people to hang a plaque on the gate of his mansion, on which were written the three big characters of "Zhongshan Village".
When the spies sent by Sima Zhao reported to him, the stone in his heart finally fell, and he understood Liu Chan's meaning, and he had the meaning of letting Liu Chan go.
Therefore, when the group of ministers was assembled not long ago, the three words on Liu Chan's door were told to the group ministers, and everyone was asked to read them backwards, and all the people present suddenly realized that Liu Chan had already regarded himself as a person living in the mountains, so there was no need to do anything anymore.
Liu Chan saved his life with his own small scheme, allowing himself to leave this world safely at the age of 64 and spend his ordinary and legendary life.
After Liu Chan's death, Sima Shi, who had successfully usurped the throne, made him the Duke of Si, which can also be regarded as the completion of merit.
Liu Chan's life is full of all kinds of dramatic colors, some people think he is cowardly, some people think he is wise, it can be said that each flower has entered each eye.
However, when we look at Liu Chan with a normal heart, we find that he is a person with a basis for retreat, and when there is a backer, he will make a big show, go all out, lose the backer, and be a man with his tail between his legs.
In the face of the natural law of survival of the fittest, is it not also a great success to save yourself, try to live to the end, and become the ultimate "king of the leftovers"?
