Gou Jian became king after he ascended the throne, and He Lv, the king of Wu, took the opportunity to attack Vietnam. Yue sent people who committed capital crimes to Wu Jun in three rows, shouted loudly, and then drew out their swords and committed collective suicide. The Vietnamese army stormed while Wu Jun was watching, and Li Yu was defeated by Wu Jun. He Lv was shot and his finger was injured, and he died of his injuries soon.

Fu Cha, the son of He Lv's last wish, said, "Never die!" Fu Cha acceded to the throne as Queen Wu, and made great efforts to prepare for revenge. Gou Jian refused to listen to the dissuasion, rushed to send troops to attack Wu, and was defeated by Fujiao (now Taihu Lake in the southwest of Wuxian County, Jiangsu Province). Wu Jun occupied Huiji Mountain in Du Yue and besieged Gou Jian in Huiji Mountain.

It is suggested that Gou Jian request Wu to surrender with humility. Otherwise, Gou Jian will personally go to Wu as a hostage. Gou Jian adopted this suggestion, and while preparing to die, he sent literary talents to make peace with the king of Wu, bribed the king of Wu with treasure, and presented the beauty stone. Fu Cha, persuaded by Aibo, made peace with Yue and led the army back to China.

Gou Jian condemned himself by writing a letter to the subjects of Yue State, and then went to Wu State to be a slave of Fu Cha and tasted shit himself. Finally, he won the trust of Fu Cha, and was released back to Vietnam three years later.

After returning to China, Gou Jian vowed to avenge Wu, recuperate, reuse, Wenzhong and others. "Ten years of reunion, ten years of lessons" and "Biography of Historical Records of Huo Zhi" said: "The more Ji Ran used the fifth strategy, the more proud he became." He also said: "After ten years of hard work, the country is rich and the people are strong, and the soldiers are generous.

When you go to Yashi, you are thirsty for a drink. Then he reported to Wu Qiang, watched the soldiers and China, and was named the five tyrants. "One year, the State of Yue presented steamed seeds to the State of Wu, which made the State of Wu hungry and cold in the second year and weakened its national strength.

In the first 482 years, Gou Jian took advantage of Fuxi's northern expedition to compete for hegemony in Huangchi, entered Gusu and Wudu, and killed the king of Wu. After returning home, Fu Cha was forced to make peace with Gou Jian. Soon, Gou Jian attacked Wu again.

In the twenty-fourth year of Gou Jian (473 BC), the Vietnamese army besieged Wudu for three years and finally broke the city. Fu Cha was trapped in Gusu Mountain, but he committed suicide because he could not surrender, and Wu died. Gou Jian then moved north to Langya, where he joined forces with the princes of Qi and Jin in Xuzhou (now south of tengxian). "The Vietnamese army is rampant in the middle of the river and Huaidong, and the vassal Bi He is called the overlord." "Twelve princes of the four countries led nine barbarians to Korea."

Zhou Yuanwang was officially recognized as the overlord.
