Sun Wu was persecuted by his political enemies, so he entered Wu from Qi and lived in seclusion in Luofu Mountain. After being recognized by Wu Zixu, he visited Luofu Mountain seven times and summoned Sun Wu to serve under King Helu of Wu. Chu State repeatedly disturbed the border and wars continued. Sun Wu promulgated the Zhao family's land tax system to strengthen the country's strength. He also divided troops with Wu Zixu to weaken the Chu army. With the help of Cai and Tang, the conflict between Wu and Chu finally kicked off.
The battle between Wu and Chu was Sun Wu's first and only actual combat. The battlefield is changing, the enemy and ourselves are intertwined, and people's hearts are confused. Sun Wu used 30,000 Wu troops to defeat 200,000 Chu troops. He used "Sun Tzu's Art of War" to his perfection, defeated Chu generals Zichang and Shen Yinshu, and helped King Helu of Wu seize control of Chu Ying. This is a typical battle in the history of ancient Chinese wars, in which a small number defeated a large number, with the greatest disparity in strength between the two sides.
After entering Chu, Chu Yingbo was treacherous and treacherous, and Sun Wu was framed repeatedly. The Chu people borrowed Qin soldiers, and Fu Gai rebelled and proclaimed himself king. Sun Wu welcomed him with a pure heart, and finally won the trust of the King of Wu and the Chu people. Wu and Chu stopped fighting and ended the dispute.
After returning to the country, the King of Wu wanted to worship Sun Wu as a general and command the three armies. Sun Wu refused to accept his resignation, and finally returned to Luofu Mountain with his beloved wife Bao Jiang to live in seclusion, and from then on they did not care about worldly affairs.
