From the beginning of the Xia Dynasty to the end of the Qing Dynasty, China can be said to have gone through many dynasties. The birth of a new dynasty is destined to be accompanied by the demise of a long dynasty, so the kings of ancient China can be said to be very numerous.

In the eyes of ordinary people, to become the king of the subjugated country, it must be the emperor himself who is absurd or inaction, such as Xia Jie, such as Hu Hai, such as Li Yu, who is the most suitable poet instead of an emperor. However, there are also some emperors who have the urgent idea of reorganizing the imperial program, and have made efforts to this end, but in the end they cannot reverse the trajectory of history, such as the Chongzhen Emperor (if you do not count the Southern Ming Dynasty, the Chongzhen Emperor is the king of the Ming Dynasty), such as the Han Xiandi.
Emperor Xian of Han? It is estimated that some people will have doubts, is this not a cowardly and incompetent emperor, who was "blackmailed by Cao Cao to order the princes" for so long, and finally ceded the throne to Cao Pi. But was Emperor Xian of Han really like this? It was not that he had not resisted, but all his efforts had been in vain.
First of all, Liu Xie was not the heir of the orthodox emperor, his mother was only Wang Meiren (later posthumously honored as Empress Linghuai), and because he gave birth to Liu Xie, he was killed by Empress He, so liu Xie did not say that he received any imperial education, and it was very good that he could save his life. When Dong Zhuo rebelled and deposed The Young Emperor of Han, Liu Xie, and established Liu Xie as Emperor Xian of Han, Liu Xie was only 9 years old. Dong Zhuo was even less likely to give Liu Xie any opportunity to receive an education, and from then on Liu Xie became a puppet emperor.
Although Wang Yun planned to kill Dong Zhuo, Dong Zhuo's generals Li Dai and Guo Feng killed Wang Yun in turn, not only controlling the Eastern Han dynasty, but even slaughtering Chang'an. After the plot, everyone must understand, originally Xun Yu adhered to the way of a gentleman and advised Cao Cao to "feng tianzi has ordered the princes", but Cao Cao was too ambitious, and changed "feng tianzi" into "feng tianzi", and Liu Xie was once again called a puppet emperor.
When subject to Cao Cao, Liu Xie rebelled twice, the first resulting in Dong Guiren's pregnancy, Dong Guiren's father Dong Cheng and other helpers were also killed; the second time Empress Fu was deposed, and finally claustrophobic and died, Liu Xie was forced to marry Cao Cao's 3 daughters, and also established Cao Jie as a queen, and has been depressed ever since.
Liu Xie was able to survive under the control of Dong Zhuo, Wang Yun, Li Dai, Guo Feng, Cao Cao, etc., during which many times he resisted at least to protect himself without worry, and in the end, even if he was forced by Cao Pi to give him the Zen position, he was not killed by Cao Pi afterwards, and lived for another 14 years before he died, which can be said to be very clear about his talent. So the question is, since Emperor Xian of Han was not a useless person, but had certain ambitions and ideas, then why didn't he defect to Liu Bei, the emperor of han, after being deposed by Cao Pi?
Because Liu Xie saw Liu Bei clearly from the beginning, Kuang Fu Han Room was just an excuse, and it was a fact that he wanted to compete for the world. As soon as Liu Xie abdicated, rumors spread in Shuzhong that Emperor Xian of Han had been killed by Cao Pi, and Liu Bei was "distraught" and "helpless to claim the title of emperor" for the sake of Han orthodoxy. To say that Liu Bei did not know whether Emperor Xian of Han was dead or not, was it possible? Moreover, Shuzhong was originally Liu Bei's territory, and this rumor would flow out, who gave it, is this still necessary to ask?
This is why Emperor Xian of Han laughed when he heard that Liu Bei was called emperor. This laugh was not a relief, but a mockery of Liu Bei's wolf ambitions. He preferred to be controlled by Cao Pi rather than defect to Liu Bei, just to preserve his only dignity, and did not want his own serious Han imperial heir to make a wedding dress for Liu Bei.
