The first one is Lu Bu. Lyu3 bu4 in Romance of the Three Kingdoms has a great reputation, commonly known as invincible. I have never lost in my life. It's really amazing.
There are many powerful people in the Three Kingdoms, and heroes are a dime a dozen. It is very rare for Lu Bu to stand out from so many outstanding figures and be invincible, which is why the words "Lu Bu among people" and "Lu Bu wins the world" came into being. When ordinary people see these words of praise for Lu Bu, they will naturally think that he is a hero with unparalleled martial arts, ranking first in the list of heroes in the Three Kingdoms. Many people were persuaded.
But if you study this book carefully, you will find that this is not the case. He seldom fought with the famous soldiers of the Three Kingdoms, only once with three brothers in Taoyuan, and finally escaped. And his ever-victorious record comes from fighting those very weak people. It's like wrestling a Hercules with an ordinary person, and the result can be imagined. Lyu3 bu4 in history is not as powerful as boasted in the romance, nor is it really invincible.
There is another person who was also in the Three Kingdoms period, and this person is Ma Su. He is as knowledgeable as Zhao Kuo, but he has the same problem. Ma Su is very clever and likes to study the strategies of Sun Tzu's Art of War. Zhuge Liang has a good relationship with his brother and appreciates Ma Su.
The two often talk about astronomy, geography and military strategy. Masu is a thoughtful man. He sometimes tells Zhuge Liang his different opinions, which makes Zhuge Liang more convinced that Ma Su is good, and such talents are hard to find. From then on, Zhuge Liang left a place for Ma Su in his heart.
Later, Guan Yunchang and Zhang Fei, a Yan man, died one after another, leaving the country with no generals to defend against foreign enemies. Zhuge Liang thought of Ma Su at this moment, and he decided to reuse Ma Su to make contributions and realize his ambition. Ma Su led the army to the street pavilion and arranged it according to the strategy in the art of war. But the result was trapped in the mountain, and finally the soldiers had to run down the mountain to surrender. This failure greatly weakened the strength of Shu, and also had a great impact on Zhuge Liang's overall strategy.
There are many people in name only, who are praised by others, complacent and forget their true strength. Such people will eventually harm others, themselves and even the country. I really don't know what this means. Be cautious and modest, arrogance is not desirable. Only by establishing a correct concept can we avoid disasters.
