"? Hard work, God will not let you down, sleep on the fuel and taste the gall, three thousand Yue Jia can swallow Wu" This famous saying tells the story of King Gou Jian of Yue who endured the humiliation and endured the heavy burden, worked on the fuel and taste the gall, and finally destroyed the state of Wu. King Gou Jian of Yue killed King Fu Chai's father, but Fu Chai released Gou Jian during the crusade, which led to the destruction of the country.

The Kingdom of Yue and the Kingdom of Wu are neighboring countries, and Yunchang, the father of King Goujian of Yue, and Helu, the father of King Fucha of Wu, formed a liaison in their early years. Later, when Yunchang died, Helu took advantage of Goujian to succeed him. He raised his troops to attack Yue. Unexpectedly, Gou Jian led his army and rushed into Wu's army. They fought hard and shot Helu. Helu died on the way back to the country after Wu was defeated. Before he died, he warned Fucha that he must destroy Yue and take revenge. After Fu Chai succeeded to the throne, he was diligent in government affairs, constantly trained his army, and managed the country in an orderly manner. He never forgot the revenge of killing his father.

Gou Jian has been proud and complacent since he won the last battle. He knew that Fu Chai wanted to attack Yue, so he was ready to strike first. The doctor Fan Li wanted to stop him, but Gou Jian refused to listen. As a result, he was defeated by Fu Chai. Gou Jian and the remaining soldiers were trapped on Kuaiji Mountain by Fu Chai. Gou Jian regretted it very much at this time and asked Fan Li what he should do now. Fan Li said that he should send generous gifts and ask for peace from Wu. Gou Jian could only accept this proposal. ?

Gou Jian sent the official Wen Zhong to express his request, but Wu Zixu, the Prime Minister of Wu State, rejected it. Gou Jian thought there was nothing he could do, so he was about to kill his wife, destroy the treasures, and fight to the death with Wu. However, Wen Zhong said that he learned that Bo Pi, the deputy general of Wu State, and Wu Zixu had always been at odds with each other, and that he was a greedy and lustful person, so he sent someone to bribe Bo Pi. Bo Pu then went to Fu Chai's place to say good things to the Yue Kingdom. Fu Chai was also persuaded by Bo Pu and felt that there was no possibility of Gou Jian rebelling again, and he was very proud and complacent. No matter how Wu Zixu tried to stop him, he refused to listen. Fu Chai ordered the troops to retreat and let Yue go. After Gou Jian returned to the State of Yue, he began to work hard to strengthen himself, secretly formed an army, and finally wiped out the State of Wu.
