Pang Juan and Sun Zhen, both of whom were students of Ghost Guzi. Pang Juan felt that his talent was inferior to Sun Zhen's, so he poisoned Sun Zhen's hand, and Sun Zhen stabbed the words on his face, dug out his patella, and lost his feet, resulting in his permanent disability.
Sun Bing pretended to be crazy and foolish to escape from the State of Wei, and in the State of Qi assisted the general Tian Ji in killing Pang Juan in the Battle of Maling, and finally took revenge. "Encircling Wei and saving Zhao", "Battle of Maling" and "Battle of Guiling" made Sun Bin shine in history.
In Pang Juan's view, the era in which they lived was a bad thing, but they still paid attention to the set of "no doctor, no courtesy to the common man". At this time, Sun Bing was already a tortured body, and there would be no state to use Sun Bing, even if he was talented. But he did not expect that the Qi State would reuse him, and only later did Sun Bin work as a strategist in the State of Qi, using the trick to shoot Pang Juan into a sieve.
Han Fei and Li Si were also brothers in arms and studied under Da Ru Xun. Both were smart and studious, but Han Fei's learning was above Li Si's. After completing his studies, Lisi went
Qin Guo, who became Lü Buwei's protégé, later became the Minister of Qin.
When Han Fei returned to Korea, due to the suspicion of the monarch and his stuttering, the expression was not smooth, and Han Fei could not be reused. Han Fei has strong writing ability, and has written his governing strategy into a book "Han Feizi". Qin Shi Huang accidentally got this book, everyone appreciated it, summoned Han Fei, and Li Si was afraid that after Han Fei's arrival, he would be surpassed by him, and his position was not guaranteed, and he had painstakingly managed the position of chancellor for many years, so he would not give it to people, so Li Si took the opportunity to enter the rumor and kill Han Fei. Han Fei died tragically in prison.
Pang Juan and Li Si are both narrow-minded and do not allow others to be above them. But Li Si was more ruthless than Pang Juan, who left Sun Zhi with a life, and Li Si may have learned Pang Juan's lesson and left no way back for Han Fei.
The reason is related to their growing environment.
Pang Juan came from a poor family and grew up among the weeds. It is neither the second generation of the rich nor the second generation of officials. He had nothing but passion and talent. However, they lived in an era where talent alone could not be done, and how could they be easily appointed without a good origin?
Li Si was also a commoner, and when he was young, he was just a small official in the township, living his life plainly, until he saw the difference between the rats in the granary and the toilet. Li Si once wrote to the teacher: Low status is the greatest shame, and poverty is the greatest sorrow.
It is conceivable that once they gain power, they will never give up until they reach their goal, and they will not allow others to be stronger than themselves.
This is also the failure left by two people in history.
And what about Sun Bing and Han Fei? One is a descendant of Sun Wu and the other is a Korean prince. They come from a superior background, have no worries about no ladder to advancement, and have no worries about the future.
In fact, the height of the birth, there is no big trouble, I am afraid of being born poor and the heart of gain and loss is heavy, and the mind is not broad enough. This is prone to tragedy...
