In 496 BC, Betty Wong Yunchang died and his son Gou Jian succeeded to the throne. He Lv Gou Jian, the king of Wu, sent troops to attack Vietnam when Vietnam was in turmoil. The soldiers and civilians all over the country hated Wu's taking advantage of people's danger, rose up and stubbornly resisted, crushed Wu Jun, and He Lv, the king of Wu, was wounded and died on his way home. Fu Cha, the prince of Wu, succeeded to the throne and devoted himself to preparing for the war for three years. In 494 BC, he led a vengeful army to kill Yue. The water army of the State of Yue was almost wiped out, and Gou Jian, the king of Yue, fled to Huiji Mountain, and the State of Yue and Wu humiliated and made peace. Gou Jian, the King of Yue, took his wife and minister Fan Li to the State of Wu for hard labor at the request of the State of Wu. The King of Yue showed He Lv the grave, fed Fu Cha the horse, took off Fu Cha's shoes and waited on Fu Cha in the toilet. Gou Jian was laughed at and humiliated. In order to restore the country, Gou Jian stubbornly endured the mental and physical torture of Wu, and was more respectful and tame to Fu Cha, the king of Wu. Fu Cha was ill. Gou Jian observed his feces to see his condition. Fu Cha was very moved. After three years of hard labor, the king of Wu released Gou Jian and returned to China. As soon as Gou Jian met the ministers, he cried bitterly and decided to take revenge. Gou Jian never forgot Wu's humiliation after he returned to China. I lie on firewood when I sleep, and I can't sleep at night. Open your eyes is to work hard and get revenge as soon as possible! Gou Jian hung a gallbladder in his room, and every meal should be tasted bitter to remind himself that he would never forget the suffering and humiliation in Wu. He wore coarse clothes and ate, plowed and sowed with the people. Mrs Gou Jian leads women to develop sericulture and weaving. Gou Jian's husband and wife share weal and woe with the people, inspiring the whole country and Qi Xin to make concerted efforts and work hard to destroy the shame of Wu at an early date. Gou Jian also bribed the prince of Wu with the minister's advice to paralyze the other side; Buy the grain of Wu, and make the grain depot empty; Giving wood costs Wu manpower and material resources to build a palace; Spreading rumors, alienating Wu Guojun and killing Wu Zixu; Use honey trap to kill the energy of Fu tea, don't ask the topic, and speed up Wu. Gou Jian's honey trap is the best. Fuxi was puzzled by the beauty of the beautiful woman Shi, and went to extinction step by step according to Yue's wishes and envisaged steps. In 482 BC, the King of Yue came to Huangchi with Fu Cha, and the attack on Wu was successful, so Wu had to make peace. Later, the State of Yue rose again and destroyed the State of Wu. Focha committed suicide. The story that Gou Jian tried his best to cure Wu has been circulated. However, some people ask: Is there really such a thing as "sleeping on salary and trying to cure Wu" in history? The history of Ding Gong and Ai Gong in Zuo Zhuan recorded the state affairs of Gou Jian, the king of Yue, in great quantities, but did not mention that he had a hard time. Guo Hua's Wu Yu and Yu Yue recorded wuyue's struggle, but did not describe Gou Jian's hard struggle. In Historical Records of Goujian's Family, only Goujian is recorded: the gallbladder hangs in front of the bed, which can be seen when sitting or lying down, and can be tasted when eating. Sima Qian believed that Gou Jian had the taste of courage and resourcefulness, but he didn't mention the matter of sleeping on his laurels. When did this idiom appear? Su Shi, a writer in the Northern Song Dynasty, wrote an article "Quasi-Sun Quan Answers Cao Cao's Book". In the Northern Song Dynasty, Su Shi wrote a false letter to Cao Cao for Sun Quan of the Three Kingdoms. In the letter, Su Shi used his imagination and joked that Sun Quan "tasted courage". This imaginary thing has nothing to do with Gou Jian. In the Southern Song Dynasty, in the Legend of Zuo's Family, it was said that the tea of the King of Wu "sat on the salary and tasted the courage". Zhang Pu of Ming Dynasty said in Chunqiu that Fu Cha's position was to avenge his father and encourage himself. This sentence carried Focha out, and he was fine. Books in the Southern Song Dynasty mentioned many times the scripts of Huan Xi Sha written by Gou Jian, the King of Yue, and Liang Yu in the late Ming Dynasty, and tried their best to render the heroic deeds of Gou Jian's painstaking efforts and hard work. Feng Menglong, a writer in the late Ming Dynasty, also mentioned the story of Gou Jian's hard work many times in his own history. Right and wrong, there is no agreement. "Biography of Gou Jian Returning to China in the Spring and Autumn Period" records that after Wang returned to China, he honed his body and mind and practiced hard day and night. When you are extremely sleepy, "attack the enemy." Polygonum hydropiper is a very bitter dish. If there are a lot of Polygonum hydropiper dishes, it means Polygonum hydropiper pays. When Gou Jian was sleepy, he used bitter vegetables to stimulate his eyes and nose to dispel his drowsiness. "Taste the gall" means tasting the bitter taste in the mouth, and "lying on the salary" means "attacking it with your eyes lying down" and not letting your eyes close to sleep. Later generations described "lying on the salary" as lying on firewood, which was a misunderstanding and misinformation in Wu Yue Chun Qiu. For thousands of years, stories of hard work and courage have inspired people. If it is false, the world will be awkward in the future. If it is true, there is a lot of evidence to refute. In short, it is difficult to tell the truth from the false.
