The Three Kingdoms period was one of the military climaxes of China's cold weapon era. At that time, there was not much difference between the north and the south in the specific combat mode of one-on-one combat, that is, two people fought against each other, but there was a great difference in the application of this combat mode.

During the Three Kingdoms period, there were generally two kinds of fighting methods: military commanders fighting and melee fighting. The battle of military commanders is a one-on-one battle between military commanders, and the rest of the soldiers will line up to watch the battle. This way of fighting originated from the end of primitive society and continued until the middle and late Ming Dynasty, and has long since disappeared in modern wars. Melee means that all soldiers participate in the battle and fight together. This method originated from primitive society and continued into modern war. The influence of military commanders' one-on-one combat on war is mainly morale. During the Three Kingdoms period, when the northern armies fought each other, they often fought one-on-one with military commanders to destroy the enemy's morale, and then attacked on all fronts to completely destroy the enemy. The southern army tried to avoid this way. This is related to the difference in physical conditions between the north and the south. At that time, the northern Central Plains was full of strong China people, and the early China people had better physique than the modern northern Han people, and their personalities were relatively rough. They like to fight alone, so they like to start a war with fierce fighters. Southerners at this time, especially Wu people, are mostly China people who have just started to merge, and their blood is relatively tall and thin, which is not suitable for one-on-one happeneth with northerners. Therefore, at this time, the Confederate army paid more attention to tactics and cooperation. There were 20 outstanding generals in the Three Kingdoms period: Lu Bu, Guan Yu, Zhao Yun, Dian Wei, Zhang Fei, Ma Chao, Chu Xu, Huang Zhong, Zhang He, Huang Xu, Wei Yan, Sun Ce, Taishi Ci, Gan Ning, Pound, Yan Liang, Wen Chou, Cao Zhang, Xiahou Dun and Ma Dai. Only Sun Ce, Huang Zhong and Wei Yan belong to the south of the Yangtze River. And the typical Wu people, Sun Ce is the only one. There are many famous Wu Dong soldiers in the Three Kingdoms, but Sun Ce is the only southerner born and raised who can fight alone with the northern generals. Others, such as Cheng Pu, Huang Gai, Zhou Tai, Ding Feng and Ling Tong, are all melee generals.
