Both Pang Juan and Sun Bin lived during the Warring States Period, a period of Chinese history characterized by frequent wars and divisions between princes.
Pang Juan was originally an ordinary soldier in the state of Chu, but he stood out with his intelligence and outstanding military talents, and eventually became an important adviser to the king of Chuzhuang.
Sun Bin was a citizen of Qi, and he also showed outstanding military wisdom in the face of political chaos and war in Qi, and became the strategist and general of the King of Qi.
The feud between Pang Juan and Sun Bin originated from a personal grudge. According to legend, Pang Juan was Sun Bin's master, but parted ways due to an argument.
Pang Juan believed that his plan had been copied by Sun Bin, which led to resentment and hostility. This personal feud eventually devolved into an open feud between the two advisors.
The feud between Pang Juan and Sun Bin was not only the result of personal grudges, but also influenced by the politics of the Warring States at that time.
Chu and Qi were two competing powers, and the conflict of interests and competition between them affected the positions of Pang Juan and Sun Bin. Pang Juan served the state of Chu, while Sun Bin served the state of Qi, and their feud was actually a reflection of the political interests of the two countries.
Pang Juan was known for his excellent military strategy and tactics, and he provided many important strategies for the king of Chu Zhuang in the state of Chu, helping the state of Chu to achieve victory in the war.
His strategy was mainly focused on how to confront the Qi State and weaken the power of his rivals. Pang Juan's military prowess made him an important pillar of the Chu regime, but it also complicated his rivalry with Sun Bin.
As Pang Juan's opponent, Sun Bin not only excelled in military strategy, but also used political means to fight back. He developed a series of strategies for the king of Qi in the state of Qi, trying to weaken the power of the state of Chu and thus form a confrontation with the state of Chu that Pang Juan served.
Sun Bin's counterattack gave him an important position in the Qi state, and at the same time sparked a rivalry between him and Pang Juan.
