During the Three Kingdoms period, the geographical location and training policies of the three countries were different, so the output of talents was also different. For example, Cao Wei, because Lao Cao originated in the north, spanning the north and the Central Plains, has a wide variety of talents, and Cao Cao likes to promote the poor, so his children's poor talents are all-inclusive, which can be said to be the most balanced. Representative figures are Guo Jia, Dian Wei and, of course, the son of Cao Jia himself.

Shu Han is simple and clear, because most of Shu Han's talents come from three places, Xuzhou, Jingzhou and Xichuan Yizhou, and some of them are Mijia, then from Jingzhou School, represented by Zhuge Liang, and then from Xichuan Yizhou School, represented by Fazheng. It can be seen that there are many counselors and few military commanders, and later military commanders are quite lacking.

The composition of Dongwu military commanders is very complicated, but most of them are similar, and they are all aristocratic families. Jiangnan aristocratic families have always been the main supporting force of the southern regime, and they control most of the power of the southern regime. Three of the four governors of Dongwu came from noble families. Zhou Yu's Luoyang has made Zhou Yi's son Zhou's children and Lu Xun's lujia's children a big family in Dongwu, but they have declined. Lu Su is also a noble family, but it may not be that big.

It is not a coincidence that Lv Meng, Zhou Yu and Lu Su died early, but that all three of them are actually very weak, and all three of them are civil and military generalists who can fight, so it is inevitable to leave a dark wound. Although Lu Su didn't often go to the battlefield, he was ill, so he died early. None of these three deaths will get in the way.
