Liu Bei had the "Five Tiger Generals" under his command, each of whom had the courage of a thousand men, and could take the first rank of general in a million troops, such as probing for things, which was an important task for Liu Bei to create a foundation, but compared with the famous generals under Cao Wei and Eastern Wu, Liu Bei could use and the number of generals who could be used and could be used was still relatively small, so that in the later period, it fell into the situation of "no general in Shu, Liao Hua as a pioneer".
In fact, in addition to the Five Tiger Generals, Liu Bei should have had a powerful general, that is, Tian Yu, who was Liu Bei's early brother in jieyi, whose martial arts were even higher than the "Five Tiger Generals", and whose military wisdom exceeded most of the Five Tiger Generals, but he ran to Cao Cao and entered the Cao camp, made meritorious contributions in Cao Wei's army, and was able to be crowned marquis.
Tian Yu was born in 171, a Native of Yongnu, Yuyang, a full ten years younger than Liu Bei. If we remember Bai Juyi's "Yuyang Nai came agitated", we can know that Tian Yu was born a northerner, so he defected to the northern prince Gongsun Zhan. This has something to do with Liu Bei, because Gongsun Zhan is Liu Bei's brother-in-law, and they are all disciples of the scribe Lu Zhi, and Liu Bei is mixing seniority under his brother at this time.
After Tian Yu saw Liu Bei, he decided that he must be very extraordinary in the future, and Liu Bei also believed that Tian Yu's talent was quite outstanding, coupled with the fact that the two of them were extremely close to each other, so they soon formed a very deep friendship, slept and worked together, and married as brothers, agreeing to do a big cause together in the future.
However, Liu Bei was later appointed as the Taishou of Yuzhou and had to go to Yuzhou to take up his post, but Tian Yu was unable to accompany him. Because Tian Yu's home was in Yuyang, if he left, he would no longer be able to properly filial piety to his mother, and during the Han Dynasty, filial piety was the most important virtue, and the emperor's title had to add a word of "filial piety", and no one could criticize Tian Yu's reasoning.
So Liu Bei and his brother Tian Yu experienced a parting, Tian Yu rode out of Liu Bei for dozens of miles, and finally had to separate, the two quietly held each other's hands, crying a mess, Tian Yu tearfully said to Liu Bei: "Hate can't achieve great things with Jun!" ”
That is to say, Tian Yu believes that Liu Bei must be a person who can achieve great things, and he has also thought of going with him to achieve great things, but the actual conditions do not allow it. Liu Bei went to Yuzhou, and later gradually founded Shu Han to become a generation of emperors, and Tian Yu himself mixed well, he was originally under the command of Gongsun Zhan, and after Gongsun Zhan's defeat, he defected to Cao Cao.
Tian Yu initially followed Cao Cao's son Cao Zhang (Huang Shu'er) and helped Cao Zhang with many key suggestions, and it was under his planning that Cao Zhang easily pacified many counties; later he became nanyang Taishou, and in less than a month, he restored peace and stability to Nanyang, where thieves were prevalent; and his most powerful political achievement was obviously to guard the northern frontier, so that many barbarians did not dare to invade the frontier.
On the whole, Tian Yu not only has the ability to understand people and govern the local people, but also can make overall plans, personally go to the battlefield to lead soldiers to fight, and his personality is also extremely calm, if he has been following Liu Bei's side, then Liu Bei's Shu Han clique may really be able to succeed in the Northern Expedition. What do you think about that?
