History is the memory of things that have been said and done. —Carl Baker
During the Three Kingdoms period, the active liu surname figures were Liu Bei, Liu Biao, and Liu Zhang, Liu Bei had great ambitions, Liu Biao was the lord of the city, Liu Zhang was faint and weak, and it was obvious that Liu Bei was victorious over the other two Han clan relatives. Interestingly, the sons of the two of them, Liu Zhang's son can be said to be the son of Liu Bei and Liu Biao. Why? Also invaded by the enemy, Liu Zhang's son Liu Xun held the city for a year, Liu Bei's son Liu Chan surrendered his weapons and surrendered the country, and Liu Biao's son Liu Chun took the initiative to surrender and abandon Jingzhou.

Liu Zhangsheng had two sons, the eldest son, Liu Xun, who was quite capable. At that time, Liu Bei set out from Yemeng Pass to kill Chengdu, taking the important stronghold of Luocheng, and it was Liu Zhang's son Liu Xun who guarded the city, and the "Romance of the Three Kingdoms And Liu Bei Biography" recorded: The first lord marched to weiluo, and Shi Zhangzi followed the defense of the city, and was attacked for a year. This means that Liu Bei attacked Luocheng and fought for a year before taking it down, and Pang Tong was also killed in this battle.
It should be known that at that time, Liu Bei fought all the way down smoothly and smoothly, Liu Zhang's subordinates surrendered and surrendered, and those who were killed were killed. However, spending so much time on the fortress of Luocheng was very unfavorable to Liu Bei's group. Liu Bei's group had Sun Wu in the east and Cao Wei in the north, all of which were looking at the tiger, and it was necessary to take Yizhou in the shortest possible time and gain an advantage in time. It can be said that this year's exile basically doomed Liu Bei to be impossible to unify the world.
It is not an exaggeration to say this, liu bei just took Yizhou, Sun Quan came to attack Jingzhou, so Liu Bei's army went east again, Cao Cao came to fight Hanzhong, Liu Bei and Sun Quan temporarily divided Jingzhou equally, Liu Bei's army went to the northwest again, Liu Bei's army felt that it had been on the road in recent years, it had not stopped, it could not be said that it was not busy!
Returning to the truth, Liu Xun's defense against Liu Bei's army for a year was a defensive miracle, and Liu Xun's courage and courage were worthy of affirmation.
Let's talk about Liu Zhang's second son, Liu Yan (chǎn). After Liu Zhang surrendered, Liu Xian followed Liu Zhang into exile in Jingzhou, and Sun Quan reused him after invading Jingzhou. According to the Book of Wu, he said: He was a gentleman, a man of courtesy, light wealth and love of righteousness, and a wind of benevolence, and he finally died at home. To put it simply, Liu Yan is a good person and has a celebrity style.
In 225, the Shu Han dynasty's southern central region of Yong Min rebelled and secretly communicated with Sun Quan, who of course responded to him and nominally appointed Liu Yan as the Assassin of Yizhou. After Zhuge Liang pacified Nanzhong, Liu Yan held a very high position in the Eastern Wu official Yushi Zhongcheng .
What about Liu Biao's son? Liu Biao had three sons, the eldest son Liu Qi, the second son Liu Chun, and the third son Liu Xiu.
Liu Qi's life is charity, and there is no big deed. He was squeezed out of Jiangxia by his brother Liu Chun's clique and died of illness early, and his army was naturally absorbed by Liu Bei. Not to mention Liu Chun, under the persuasion of Ku Yue, Han Song and others, Liu Chun offered Jingzhou to Cao Cao, and later served as a counselor in the State of Wei. Liu Xiu also served as an official in the State of Wei.
Even Cao Cao once lamented: When you have a son, you should be like Sun Zhongmou, and Liu Jingsheng's son should be like a guinea pig!
Speaking of Liu Bei, Liu Bei's precious son Liu Chan, presumably everyone is familiar with it, similar to Liu Chun, Deng Ai's army was killed, and under the persuasion of Tan Zhou, the whole country surrendered. Liu Chan's nature was more serious than Liu Zhen's, and he was carrying a country, while Liu Chun was just a state. After that, Liu Chun was still an official in the State of Wei, while Liu Chan was eating, drinking and having fun.
Of course, Liu Bei also had two sons, namely Liu Yong and Liu Li, and in 230 AD, Liu Yong was made the King of Ganling and Liu Li was made the Prince of Anping. Liu Li died early, and Liu Yong became an official in the State of Wei after that.
Comparatively speaking, Liu Zhang's sons were much more powerful than Liu Biao and Liu Bei's sons.
