During the Three Kingdoms period, the world was in chaos and the masses were divided, and during this period, various princes rose up to become independent, and Liu Biao was one of them. At first, Liu Biao was also a ruthless man, although he was a Han zhongren and a Jingzhou mu specially approved by Dong Zhuo, but at that time, jiangnan was very rich in thieves, Yuan Shutun was in Luyang, and his men had all the Nanyang people, Wu Ren Su dai was Changsha Taishou, And Bei Yu was the governor of Huarong County, and each according to the militia was hegemonic in the local area, resulting in Liu Biao being unable to take office directly. Under such circumstances, Liu Beidan rode into Jingzhou, and he became acquainted with the Jingzhou people Qu Liang, Pu Yue, and the Xiangyang people Cai Mao, and gradually captured Jingzhou under their suggestions, which showed that Liu Biao himself was also a very capable person. After occupying Jingzhou, Liu Biao was also one of the most capable princes at that time.
Although Liu Biao held Jingzhou in his hands, and he also had lofty ambitions, but Liu Biao was suspicious of human nature, determined to defend himself, and did not have great ambitions, so that he guarded Jingzhou without much development, in his later years, he was even more spoiled by his wife Cai Shi, resulting in his wife Cai Mao and other powers, so that after Liu Biao's death, Cai Biao's son Liu Chun succeeded to the throne, and immediately surrendered to Cao Cao, making Liu Biao's life's hard work in vain. What is strange is that Liu Biao was so weak in his later years, sun ce and Sun Quan failed to capture Jingzhou in one fell swoop. Since Liu Biao was suspicious and had no great ambitions later, why didn't Sun Shi succeed in capturing Jingzhou?
The reason why Sun Shi was unable to capture Jingzhou was mainly because Sun Shi's strength was not as good as Liu Biao's at that time. At that time, Liu Biao's soldiers had more than 100,000 soldiers, and Sun Quan's military strength at that time was about 100,000 people, of course, at the Time of Hefei, Sun Quan's troop strength was already more than 100,000, after all, if Sun Quan himself could bring out 100,000 people, then Sun Quan's total strength should be more than 100,000. Of course, in 208 AD, Sun Quan's troops should be less than 100,000, otherwise he could fully say that he had more than 100,000 people under his command, and during the Battle of Chibi, he would not only give Zhou Yu and Cheng Pu 30,000 people.
Moreover, in terms of territory and manpower, Sun Quan was not Liu Biao's opponent, in the time of emperor Han Shun, not counting Nanyang, the remaining six counties added up to nearly four million people, Nanyang if it is average, the population of the seven counties has exceeded five million, and the five counties occupied by Sun Quan, the combined population is nearly four million people, and at that time Sun Quan only occupied the part of the jiangnan of these five counties, and there was no unification. It was precisely because Sun Quan did not have the advantage in terms of military strength or population, and the same was true during Sun Ce's period, so they could not defeat Liu Biao and occupy Jingzhou.
The author believes that although Liu Biao did not have great ambitions in his later years, the number of troops in Jingzhou was still there, and under such circumstances, it was difficult for Sun To capture Jingzhou.
