For example, Gou Jian-the two sides fought in Tori (southwest of Jiaxing County, Zhejiang Province). Seeing Wu Junrong's neatness, Gou Jian organized death squads to attack several times in a row, but they were all repelled by Wu Jun. In this case, Gou Jian forced prisoners who committed capital crimes to line up in three columns, walked to Wu Jun with swords and committed suicide together. Wu Jun soldiers were stunned by this crazy move, and flocked to watch, and Wu Jun was in chaos. The Vietnamese army took the opportunity to launch a surprise attack and defeated Wu Jun. He Lv himself was injured and killed. Before he died, he repeatedly reminded his son Fuxi: "Don't forget Yue!" Fu Cha always kept in mind the revenge of killing his father, trained day and night, actively prepared for war, and prepared to send troops to attack Vietnam. In the spring of 494 BC, Gou Jian, the king of Yue, learned that Fu Cha was going to attack Yue, but he didn't listen to Fan Li's advice. In the case of inadequate preparation, he decided to take the initiative to attack Wu. Fu Cha sent all the elite soldiers of Wu to meet Yu Fujiao (now southwest of Suzhou, Jiangsu). Wu Jun fought bravely with one heart, but the Vietnamese army was defeated and suffered heavy losses, leaving only 5,000 people to retreat to Kuaiji Mountain. Wu Jun pursued the victory, occupied Huiji Mountain in Du Yue, and then surrounded Huiji Mountain. At the critical moment of life and death, the doctor put forward the idea of enduring humiliation and pursuing perfection, and advocated humble submission to Wu. If he doesn't allow it, Gou Jian will personally go to Wu as a hostage. Gou Jian adopted this suggestion, prepared to fight to the death, sent Wen Zi to make peace with the prince of Wu, bribed Wu Taizai with beauty and treasure, asked him to mediate, persuaded Fu Cha to allow Yue to be a vassal of Wu, and declared that if Wu was not allowed, he would cross the rubicon and fight with Wu to the end. Wu Zixu thought that it was better to destroy Yue State than to compete for hegemony in the Central Plains, and he saw the ambition of destroying Wu behind the courtesy of Yue's monarch and subjects, so he insisted on completely destroying Yue State, otherwise it would lead the tiger back to the mountain and save the legacy. "If you don't destroy Yue today, you will regret it later." However, Fu Cha was eager to compete with Qi in the north, thinking that since Yue surrendered, it would exist in name only, and it was not a problem. So, he promised to make peace with the state of Yue and led the army back to China. The more you experience in this war, the more strength you lose. In order to appease the people, Gou Jian wrote a letter to himself: "I don't know that I am weak, but I hold a grudge against a big country for exposing the bones of the people in the Central Plains. This is my sin, so I ask you to feel more guilty. " He also ordered "burying the dead, asking the injured, keeping in good health, worrying, congratulating, rejoicing, giving people away, welcoming people, eliminating the evil of the people and making up for the shortcomings of the people". Then, the domestic affairs were entrusted to the doctor, who took others to Wu to be slaves of Fu Cha. Gou Jian endured humiliation in the State of Wu, finally gained the trust of Fu Cha, and was released to China three years later. After Gou Jian returned to China, he was determined to restore the country and destroy Wu. The so-called "self-cultivation, wife self-weaving, food without meat, clothing is not heavy, folding sages, being kind to guests, vibrating the poor to hang, and sharing with the people." Strive for people's hearts, select talents and appoint people, let Wen Zi govern the government, Fan Li rectify the army, and set up a recruiting hall to accept talents from all walks of life. Reform internal affairs, reduce penalties, reduce taxes, reclaim wasteland, develop production, encourage fertility and increase population. Militarily, build a city and build a profile, repair the capital destroyed by the war, train the army, reward and punish severely, and expand the source of troops. In foreign policy, it pursues the policy of "uniting with the Communist Party, being pro-Chu, paying a lot of money and being lenient with Wu". Constantly give generous gifts to Fu Cha to show loyalty and obedience, so as to eliminate his vigilance against the state of Yue; Send beauty stones and give them to him, so that he can indulge in women and distract his energy; Bribing Chen Wu to win their sympathy and help; And alienate the interior of Wu and provoke discord among ministers; Destroy Wu's economy and buy Wu's grain at a high price, which makes its internal food prices soar and causes supply difficulties; Collecting excellent materials and selecting skilled craftsmen to give them to Fucha will promote its construction and consume manpower and material resources. The above measures have achieved remarkable results, strengthened themselves, weakened the enemy and won over the country. The strength of Yue has been greatly enhanced, and it is only a matter of time before he sends his troops to attack Wu. Wuyue became more and more corrupt. He worked hard to get revenge and revenge. Fuxi was arrogant because of his victory, extravagant and lustful, and militaristic. In order to build Gusutai, a lot of manpower and material resources were used, and stone worked day and night. At the same time, he was eager to threaten Qi Jin by force and dominate the Central Plains. The attack on Chen in 489 BC and the attack on Lu the following year shocked the small countries nearby and opened the way for the north to enter the Central Plains. Fu Cha also recruited a large number of migrant workers to build Seoul, as a base for going northward, digging ditches, communicating with Jianghuai and facilitating military transportation. In order to lead Wu northward into the Central Plains, make enemies with Jin and Qi and Chu, and create opportunities to attack Wu by taking advantage of weakness, Gou Jian made great efforts to Fu Cha, and asked tens of thousands of civilian workers to help Wu dig Korean ditches, so as to push Fu Cha northward. In 484 BC, Fu Cha heard that Qi Jinggong was dead, and decided to go north to cut Qi, unite with Lu Army and defeat Qi Army. After the war, Fu Cha became even more arrogant, thinking that the hegemony of the Central Plains could be realized by finally conquering the State of Jin, so he agreed that Jin Dinggong and the governors of other countries would join the Union in Huangchi (now southwest of Fengqiu, Henan) on July 7, 482 BC. Before leaving, Fu Cha turned a deaf ear to the advice that the prince's friends should beware of taking advantage of the situation. He thought that the hegemony of the Central Plains was within reach and should not be missed. So, since he led 30,000 elite soldiers to expedition to Huangchi in the north, there were only 65,438+/kloc-0,000 people left in Gusu, and the opportunity that Gou Jian dreamed of finally came. On June 12, 482 BC, Gou Jian mobilized 49,000 Vietnamese troops, divided into two roads, one led by Fan Li, and entered the Huaihe River by sea, cutting off Wu Jun's return from Huangchi. With the doctor as the pioneer, Gou Jian led the main force, and then attacked Gusu by land. The King of Wu led his troops to Shang Hong (now the suburb of Suzhou, Jiangsu) to stop the Vietnamese attack. He felt that the elite troops had gone north, and their strength was hard-won. They lived together for ten years. The lessons of ten years are inspiring. Fu Cha was arrogant because of his victory, which made the enemy suffer, prepared for danger in times of peace, and finally lost his country.
