Sun Zhen besieged Wei to save Zhao and defeated Wei Guo, and captured his old classmate Pang Juan.
Pang Juan can be described as a bloody vendetta against Sun Zhen, he trusts this old scholar, but he is framed and crippled by the other party, and his face is also engraved, and he cannot get on the horse for life.
However, in the Battle of Guiling, Sun Bin did not kill Pang Juan after capturing Pang Juan, why is this?
First, as a military master, Sun Bin did not have the power to dispose of the opposing general after he captured the opposing general.
Pang Juan was a high-ranking general of the State of Wei, and how to deal with it should be decided by the King of Qi Wei, and Sun Zhi could not dispose of it privately.
Second, the execution after the capture would leave no room for relaxation in the relations between the States of Qi and Wei.
If it was to kill Pang Juan on the battlefield, then no one had to say, after all, the sword on the battlefield had no eyes, and later Pang Juan died in the Battle of Maling.
But you have already been captured, if you kill again, it is easy to get into a stalemate with the other country's relations, and there is no way back.
Later, Eastern Wu stabbed Guan Yu in the back and killed Guan Yu, Liu Bei avenged Guan Yu with the strength of the whole country, if Cao Cao did not die, or Eastern Wu did not have Lu Xun, I am afraid that he could not resist Liu Bei's attack.
Third, Sun Bing did not take Pang Juan in his eyes.
Although Pang Juan's military level was not bad, it was obvious that Sun Zhen's level was more than one notch higher than Pang Juan's, and even if he put it back, it would not pose a threat to the State of Qi.
Fourth, as an excellent military expert and politician, Sun Bin's reason triumphed over his desire for revenge.
Pang Juan, as a high-ranking official of the State of Wei, can be used as a bargaining chip for negotiations, and if the State of Wei wants to put it back, he can also take the opportunity to knock a bamboo lever.
There is harm in killing, there is benefit to letting go, and there is no threat, so why not enjoy it?
In 351 BC, Pang Juan was released back to the State of Wei and again became a general.
