Compared with the strength of Shu in the Three Kingdoms period, the strength of Wu should be stronger. Although Shu is famous, its overall ability is average. During the Three Kingdoms period, Wei was naturally the most powerful, with the strongest attack and defense. There is no doubt that the defense of Wu is very strong, and the attack of Shu is also very strong. However, in several battles in which Wu attacked Shu, Wu Dong won a great victory, which shows that Wu is stronger. Compared with Shu, Wu's strong defense is a big advantage. Wu is good at defense, so many people think that he is not enterprising. Actually, it is not. Wu's defensive ability can make them keep up with Wei, so they develop steadily. This is a strategic issue. Shu is good at attacking. General Wu Hu? During this period, the generals of Shu were actually no worse than Wei. Needless to say, valiant generals like Guan Yu and Zhang Fei are also rare generals, so under their leadership, the military strength of Shu is actually very strong. In the war between Wu, who is good at defending, and Shu, who is good at attacking, Wu won, so the strength of Wu is definitely better. At that time, Guan Yu led a crusade against Lu Xun, Lu Meng and others. Under the guidance of Lu Xun and Lu Meng, he successfully defeated Guan Yu's army and got Guan Yu's head. Then, Liu Bei led the army to crusade against Wu Dong to avenge his brother, and he was defeated. It can be seen that the strength of Shu is completely inferior to that of Wu. The main factor causing the strength gap between Wu and Shu is the difference in talent management. The talent management in Shu is not as good as that in Wu. In the camp of Shu, Zhuge Liang, a great strategist, occupies the absolute first position, and other counselors rarely bloom themselves in his light. Among the generals, Guan Yu and Zhang Fei are stubborn and difficult to manage. On the other hand, Wu's talent management system has established a set of strict cooperation strategies, so Wu's strength will far exceed that of Shu.
