In 473 BC, Gou Jian destroyed Wu, and in 468 BC, he moved the capital from Huiji in the south to Langya in the north, which became the most prosperous moment of Yue. Later, Gou Jian died in 464 BC, and after his son Lu Ying succeeded to the throne, there was no more story of the king's hegemony. Even after 100 years, there are few records of Yue history. For example, the history books only record the names of the successive Yue kings after Gou Jian: "The king and the pawn, the son king does not live long. Before the king died, the son Wang Weng Li. When Wang Weng dies, the son is king. The king is dead, Ziwang. When the king dies, the son is not strong (also known as boundless). In addition, although the State of Yue destroyed the State of Wu, it could not completely take over the land seized by Chu in the upper reaches of Jianghuai. In 386 BC, the state of Yue moved its capital from Langya in the north to Gusu, the ancient capital of Wu in the south (Gusu was renamed Huiji after the move), indicating that the state of Yue began to lose its hegemony in the north and returned to its lair in the south. By the time the last King of Yue was in power, China was already in the Warring States Period. At that time, Wujiang wanted to imitate his ancestor Gou Jian and dominate the Central Plains, so he set out to attack Qi in the north and Chu in the west. Yue was far behind other big countries at that time, and the result was self-destruction. The following is an account of the demise of the State of Yue in Zi Tongzhi Bamboo Slips: In thirty-five years (Ding Hai, 334 BC), the State of Yue cut Qi without borders. The king of Qi sent people to say that it is better to cut the benefits of Chu than to cut the Qi, so the king of Yue cut Chu. The Chu people were defeated, taking Wu's hometown and facing Zhejiang in the east. The more dispersed the princes and clans are, the more they will try to stand out, and they will either be king or king, and they will be at sea and serve Chu. The former site of Yue State was merged by Chu State, which was called East Chu. Huiji County, where Xiang Yu rose later, was also the hometown of wuyue.

The hegemony of the former governors came to an end, and wuyue, located in Jiangsu and Zhejiang, began to develop. In the 14th year of the Zhou Dynasty (506 BC), He Lv, the king of Wu, took Wu Yuan (Wu Zixu) as the general and attacked Chu and the capital of Chu. Twenty-four years ago (496 BC), Zhou led a expedition to the south. Gou Jian, the king of Yue, led troops to fight. The doctor of Yue hit He Lv, and He Lv died of serious injuries. In the 26th year of the week (494 BC), Fu Cha, the king of Wu, avenged his father and defeated Yue. Gou Jian, the King of Yue, made peace and gave it to the precious beauty stone of the King of Wu, who personally led the horse as Fu Cha. Wu Wang's Northern Expedition defeated the Qi army and became a bully. Gou Jian, the King of Yue, lived together for ten years and finally destroyed Wu for three years (473 BC). Focha committed suicide in shame. Gou Jian went north and joined forces with Qi Jin in Xu, becoming the last overlord. When Gou Jian just wiped out the hegemony of Wu, his greatest hero was awarded the title of general. However, Fan Li knew that "it is difficult to live in a big name for a long time" and "it is ominous to be respected for a long time", so he retired immediately after his success. "Since you are a private disciple, you can float on the sea by boat and never violate it." He changed his name to Tao Zhugong and later became rich by doing business. Fan Li once sent someone to write a book, saying, "Birds are exhausted, so you can hide with a bow;" A sly rabbit dies, but a running dog cooks. The King of Yue pecked a bird with a long neck, but he shared happiness and hardship. Why not go? Wen Zi didn't listen, and soon Gou Jian gave him a sword to commit suicide. 2007-02-1912: 53: 27 Supplement: After the demise of Wu, Gou Jian went north for hegemony, running across the Yangtze River and Huaihe River, claiming to be the overlord. During the Warring States period, the national strength was weak, and it was destroyed by the State of Chu in 306 BC. 2007-02-20 00:02:32 Supplement: In addition, although the State of Yue destroyed Wu, it could not completely take over the land of Wu in the upper reaches of the Yangtze River and Huaihe River, which was seized by the State of Chu. In 386 BC, the state of Yue moved its capital from Langya in the north to Gusu, the ancient capital of Wu in the south (Gusu was renamed Huiji after the capital was moved), which showed that the state of Yue began to lose its ability to maintain its hegemony in the north.

Yue State, also known as Yue State and Wenlang [Request for Origin], is a vassal state in China's history during the Spring and Autumn Period and the Warring States Period, and may also be a truly established kingdom in Vietnamese history [Request for Origin]. The monarch's surname is Luo (also written as Luo), and some people say that it is a surname. According to legend, he is a descendant of the distant ancestor Chonglan (Luo) and a descendant of Dayu. Huiji, whose capital is located near Shaoxing, Zhejiang, China, once reached Shandong Province, China and northern Vietnam [source request], and was destroyed in Chu State. In 306 BC [1], the State of Chu conquered the State of Yue, and after that, its royal descendants were scattered in what is now southern China and northern Vietnam [source request], and each ruled separately. After returning to China, Gou Jian vowed to take revenge and destroy Wu, rest and recuperate [1], reuse and others, "once every ten years, a lesson every ten years". Biography of Historical Records of Huo Zhi said: "The more he used the fifth of Ji Ran's tactics, 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 the next 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. Gou Jian soon 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. Fuxi was trapped in Gusu Mountain and committed suicide because he could not surrender. Wu had no strength when he died.

Wu Zhuan succeeded to the throne after his death and reigned for 37 years from 342 to 306. After Chu attacked Yue, Wu Qiang was killed and died.
