At the end of the Eastern Han Dynasty, there was a severe drought year after year, and no crops were harvested. Due to the corruption of the imperial court, officials did not think about disaster relief, and taxes increased, forcing poor farmers who had no choice to rise up and the Yellow Scarf Uprising broke out. In order to quell the rebellion, the rulers of the Eastern Han Dynasty ordered the counties to raise their salaries and adjust their troops to suppress the uprising. Although the "rebellion" was finally put down, it led to the end of the rise of heroes, and the regime building in the Eastern Han Dynasty collapsed.

Among many valiant soldiers, Yuan Shao of Hebei Province and Cao Cao of Yu Yan grew up gradually in the long-term merger war. In terms of strength, Yuan Shao occupied a third of the land in Hebei, Qinghai, Youzhou and Sihou at that time. Moreover, the ancestors were famous and the advisers were like clouds, which was the most promising way to unify the north and become the largest warlord group. However, although Cao Cao was a eunuch (his father Cao Song was the adopted son of eunuch Cao Teng), he was brilliant, married, moved the capital to Xu County, held the emperor as a vassal, defeated Lyu3 bu4 and Yuan Shu successively, and occupied Yanzhou and Xu's land, with growing power. Although they have known each other since childhood and have a deep friendship when they studied together, after all, a decisive battle is inevitable, and the battle of Guandu begins.

On the eve of the battle, although Cao was weak, Yuan Shao did not make good use of it and let the fighters leave easily. Liu Bei, who was attached to Cao Cao at that time, rose up against Cao Cao and attacked Xuzhou. In order to avoid fighting on two fronts, Cao Cao could only lead a good soldier to attack Liu Bei in the east. At the height of the battle between Cao and Liu, Tian Feng, Yuan Shao's counselor, suggested "leading an army to attack Cao", but Yuan Shao refused to adopt it on the grounds that his youngest son was ill, which led Cao Cao to return to Guandu after defeating Liu Bei calmly. After losing the insider, Yuan Shaocai issued an appeal to catch the thief and dispatched troops to attack. General Yan's revenge led his troops straight to Baima, trying to control the strategic location of crossing the river, but he was defeated and defeated.

Although Yuan Jun lost the first battle, his army and food still prevailed. So Yuan Shao personally led the main force of 65,438+10,000 people to approach Guandu, confronting Cao Jun's 20,000 troops. Although the two sides were at loggerheads for three months, Cao Jun repelled Yuan Jun's attack many times, but Cao Cao's serenade was short of food and his foot soldiers were tired, so he could not keep it for a long time. At that time, Xu You, an important counselor in Yuan Jun, discovered this and suggested to Yuan Shao to continue the confrontation and divide his troops to attack Xuchang. However, Yuan Shao thought Cao Cao was cunning and didn't take the advice. Instead, he suspected that Xu You had known Cao Cao since he was a child and was suspected of collaborating with the enemy. Xu You was worried and angry. He turned to Cao Cao and suddenly attacked the Wu Dynasty and burned the trenches in Yuan Jun. Just when the lair was in danger, Yuan Shao put the cart before the horse and attacked Cao Cao's camp, but he was ambushed. A series of failures led to the internal division of Yuan Jun, his morale was shaken passively, and then he completely collapsed. Lombardi fled back to Hebei with only eight hundred riders, and Cao Jun seized numerous materials, which greatly increased his strength. This battle laid a solid foundation for Cao Cao to defeat Yuan Shao and unify the north.

The author believes that the fundamental reason why the powerful Yuan Shao lost to Cao Cao, who is weaker than himself, is not the strength of both sides, but whether the commander-in-chief is more capable and worthy of a generation of leaders. In fact, before the war in Cao Yuan, Cao Cao had talked about heroes in his childhood (similar to the work of matching futures accounts with investors' appropriate risks), and evaluated Yuan Shao's nature and weaknesses: ambitious but not ambitious, not bold enough, jealous of the outside world, indecisive, regretting his life when he did great things, and thinking that Yuan Shao Group had too many soldiers to command clearly, and would be arrogant and have different orders. From this, it can be concluded that Yuan Shao's character and talent can't hold up his huge assets, and he is not qualified to carry out a large-scale battle like Guandu in terms of strategic planning, the way of using troops and the way of taking risks. Facts have also proved that Cao Cao knows people accurately and analyzes them thoroughly. Yuan Shao failed to grasp the fighters that appeared many times, and finally lost to his own personality weakness.

Taking history as a mirror, sometimes a good product or a good strategy is not suitable for every investor, because even the best product and strategy, if mismatched because of personality weakness and risk tolerance, will also lead to investment failure. For prudent investors, if they are given a radical strategy, even if the strategy is high-yield and low-risk, prudent investors will not adopt it. Even if it is adopted, there will be deviations in the implementation process-in the process of implementing the trading plan, operational risks will occur because of differences in personality and strategy. Therefore, it is very important to match the investor's fitness, so that investors can accurately find products and strategies suitable for their risk tolerance. Don't choose the best, just choose the one that suits you best. This is what every investor needs to be aware of.
