Xu is a surname and used to be a country. In remote ancient times, it is said that a noble sage led the people to create the state of Xu. This ancient country has existed for more than 1500 years. After its destruction, a group of descendants took the country as their surname to commemorate the glory of the former family and country forever.

Xu is a familiar surname. However, few people know that the surname “Xu” originated from an ancient country – the state of Xu.

when talking about the state of Xu, we should first talk about Dayu. Dayu was ordered by Emperor Shun to control the flood and made great contributions to inherit the throne of Shun. In the process of his water control, the support of Bo Yi, the leader of the Dongyi nationality, was indispensable. Because of this, Dayu may be out of public interest in his later years, or he may be forced by public opinion to prepare for the Zen position to Bo Yi. Kebo Yi was indifferent to power and position, and took the initiative to give way to Yu’s son Qi. He lived in seclusion in the north of Jishan. According to the records of Tao yizao, Tao yizao was prepared to seize the seat of the Zen emperor, but he died.

inspired the son to inherit his father’s career and brought a major reform in Chinese history. The Zen system has become a hereditary system. The primitive society of “the world is the public” has entered the slave society of “the father passes on the son, the family and the world”. This not only changed history, but also changed the fate of many tribes of the Dongyi nationality represented by Boyi.

in 2170 B.C. (the sixth year of Xia Qi), Xia Qi killed Boyi in order to prevent future diseases. In order to win the hearts of the people, Xia Qi buried Bo Yi with heavy rites and sealed his second son Ruomu in Xu (central and southern Shandong, Tancheng area). This is the founding of the state of Xu.

during the Xia Dynasty, most of the monarchs of the state of Xu were wise and promising, and the state of Xu continued to develop. The Xia Dynasty did not dare to be careless about the state of Xu. It often carried out expedition and plundered wealth and people to weaken the strength of the state of Xu. This led to the struggle between Hou Yi, Han Zhuo and Xia. In the Shang Dynasty, the number of expeditions in Xu was greatly reduced. The people of Xu cultivated by slash and burn in this relatively stable environment and created a splendid culture in the Yellow Sea area.

by the end of Shang Dynasty, especially in the early stage, the power of Xu became stronger and stronger, even more than any previous period. From Dan Dynasty, the war between the Western Zhou Dynasty and Xu Dynasty was the most frequent among the generations of King Cheng of Zhou Dynasty and King Kang of Zhou Dynasty. The state of Xu participated in the rebellion of the remnant nobles of Shang and Yin dynasties led by Wu Geng and resisted the eastern expedition of the Duke of Zhou. The king Ju of the state of Xu set out to attack Zhou directly and hit the Yellow River. Xu’s descendants were proud of “the first king Ju asked for help in the river in the west”. Lu Hou Boqin (the son of Zhou GongDan) often clashed with Xu. According to the book of history, Lu had a fierce war with Xu Rong and Huai Yi. Lu was so threatened that he dared not open the east gate of the capital for a time. The rulers of the Zhou Dynasty always believed that the strong and prosperous state of Xu was a serious threat to the rule of the Zhou Dynasty, so they were worried about the state of Xu and attacked it frequently. In this regard, there are many records in the book of songs. In the face of the Zhou Dynasty, which came from the power of the world, the state of Xu retreated repeatedly and moved south to Sihong. At this time, the king of Xu led his troops to the West as the leader of the vassal state and confronted Zhou. King Mu of Zhou did not dare to fight with the state of Xu who came with a huge army, and recognized Xu Jun as the leader of the princes. It can be said that the state of Xu was the first legitimate overlord of the Zhou Dynasty, much earlier than the rise of the five bullies in the spring and Autumn period.

. In the middle and late Western Zhou Dynasty, the throne was transferred to King Xu Yan, and the state of Xu revived again in huaisi area. As recorded in historical data, “King Xu Yan was located in the east of the river, with a place of 500 Li. He practiced benevolence and righteousness and ceded land, and there were six kingdoms in 30 dynasties.” The revival of the state of Xu caused concern in the Western Zhou Dynasty, so he ordered the state of Chu to raise troops to fight against it. King Xu Yan was benevolent and righteous by nature. He could not bear to suffer the people of Xu and Chu because of the war. In 963 BC (from the 13th to 17th year of King Mu of Zhou), he abandoned the country and settled down at the foot of Dongshan (now Xushan in the northwest of Pizhou) in Wuyuan County, Pengcheng. Tens of thousands of people moved with him. King Xu Yan also led some people of Xu to the south by sea to Ningbo, Zhejiang Province. Finally, under the oppression of the pursuers, King Xu Yan threw Meiyu into the sea and died.

King Xu Yan was praised for his benevolence and righteousness. Zhou defeated queen Xu Yan and was forced to make Baozong, King Xu Yan’s second son, a grand duke, set the capital Pengcheng and continue to govern the state of Xu. This is the origin of today’s King Liang City. At this time, it was in the period of the king of the Zhou Dynasty (922-900 BC).

,

in the spring and Autumn period, the state of Qi and other vassal states separated and dominated, and the state of Xu moved southward again to the huaisi region bordering Huainan, Jiangbei, Jiangsu and Anhui. At that time, the state of Xu was weak, the people were relatively loose, and did not have much resistance. It was sandwiched between big countries and survived.

in the summer of 512 BC (the eighth year of King Zhou Jing), the state of Wu sent envoys to order the state of Xu (now Sixian County, Anhui Province) and the state of Zhong Wu to hand over the childe covering Yu and Zhuyong who were the leaders. Relying on the support of strong Chu, the two countries refused to obey orders, and secretly released the second childe and asked them to go to the state of Chu. Shen Zhaozi, the second son of Duke Zhaodi of Henan Province, was sent to meet the second son of Duke Zhaodi and was very proud of him. Then he ordered you Yinran and Zuo Sima Shen Yinshu to rebuild Yangcheng, and granted the two places of Chengfu in the northeast and Hutian in the southeast of Yangcheng to the second childe, in an attempt to use the second childe to harm the state of Wu. This just gave the king of Wu the excuse to send troops. In the winter of the same year, Fu Chai, king of Wu, sent his troops to the north to cross the Huaihe River to cut Xu, and let the Surabaya flood the state of Xu. Zhang Yu, king of Xu, with his hair scattered and tattooed on his face, tied himself up and led his wife to kneel in front of his husband, asking for the preservation of his land, which he was not allowed to do. In desperation, Zhang Yu fled to the state of Chu with his royal family, and the state of Xu has lost its name since then.

and

after Xia Qi was granted Ruomu to Xu for six years, the state of Xu has experienced three dynasties, including Xia, Shang and Zhou dynasties. There are 44 dynasties of kings, which have survived for more than 1500 years.

  Xu was the largest country in the Dongyi group in the Western Zhou Dynasty. Zi said that he had a territory of 500 Li. The book of songs says, “lead the huaipu River and save the xutu river.”. At present, in the vast historical documents, we rarely see the specific business status of Xu, such as the words of economy and production. But we can get some indirect things from the unearthed cultural relics, especially the archaeology of bronze inscriptions.

the unearthed relics of ancient bronze ware mainly started from the middle and late period to the heyday of the Western Zhou Dynasty. The production of bronzes marked the production and economic development of ancient society. The unearthed bronzes of the Western Zhou Dynasty have a large number of inscriptions, which confirm and make up for the accuracy and shortcomings of traditional historical documents. The records of “fujijin” in the Western Zhou Dynasty were mentioned several times. “Fu” means acquisition and plunder. “Jijin” is an excellent bronze ware. Xu Rong is the largest and representative country among the Huai

Yi tribes. Zeng Bosu’s inscriptions contain: “Ke Ti Huai Yi, Yin Xie fan Tang (Yang), Jin Dao Xi Xing”, indicating that the Huai Yi area south of Fan Yang in Anhui Province was rich in copper and tin at that time. “Xi Jia pan” bears in mind the corresponding provisions on the southern Huai Yi and the princes and people contained in the declaration of the Western Zhou Dynasty. The inscription says: “the Huai Yi used to bribe people, so I dare not leave the silk, accumulate it and enter the people.” “If you dare not to order, you will be punished and punished”. That is to say, Huaiyi must pay auspicious money, property and labor to the Zhou Dynasty, otherwise they will crusade. In the period of King Mu of Zhou Dynasty alone, the inscriptions of the war records related to the fifteen utensils and the Huaiyi were found. The book of songs% 26amp; #8226; Lu Song% 26amp; #8226; pan water describes the situation that Duke Lu conquered the Huaiyi people and built a pan palace to celebrate the group of officials. It ends with the sentence “looking forward to the Huaiyi people and offering Qichen. The tortoise in the Yuan Dynasty is like a tooth and offering great bribes to Nanjin”. The economy of the state of Xu was very developed and it was the main area providing taxes for the Western Zhou Dynasty. Therefore, “levying Dongyi” and “levying Dongguo” became the main wars after the founding of the Western Zhou Dynasty, which were also recorded in many bronze inscriptions in the early Western Zhou Dynasty. The economic development of the state of Xu can also get some impressions from the inscriptions of Xu ware, the family tree of Xu surname and miscellaneous history. For example, the “Xu Yao Yin Tang Ding” unearthed in Shaoxing is an official of the Shang Dynasty, the state of Xu and the state of Chu. “Yi Zhou Shu%26amp; #8226; Wang Huijie” has: “Zhu Huai and Rong”: “Huai and Rong are Zhu’s surnames.” Among them, the Huai family was a Huai Yi and became the witch wish of the Zhou Dynasty. It can be seen that the economic development of the Huai Yi brought cultural progress. Otherwise, the Zhou Dynasty could not easily grant the sacred position of sacrifice to a Yi person. Xu state is a representative country in Huaiyi, and has a very clear division of labor to manage officials in this regard.

the book of songs% 26amp; #8226; Lu Song% 26amp; #8226; Jiong is a chapter that praises the numerous horses raised by the state of Lu. Relatively speaking, Huaiyi is located in the crisscross of the Yangtze River and Huaihe river network, and the shipping industry is dominant. According to the genealogy of the Xu family in Yingshan, the 38th ancestor Xu Chang said, “Chang Shi’s dream is to manage the transportation and the main business of shipping. King Zhao of Zhou marched south, so that Chang can operate the boat and travel in Hanze. The boat lost its bottom. When King Zhao died, he fled to Nanchang and avenged his father.” “Department editor” is an official in charge of shipping and ships. He made a bet in connection with the article “King Xu Yan” in the previously published Chinese Dictionary: “when King Mu ruled the country, Xu Zi heard about benevolence and righteousness, and wanted to sail to the country, but between Chen and CAI…” Xu actually wanted to dig a canal with the advantage of shipping, and his national strength can be imagined.

many people know the stories of “Hou Yi shooting the sun” and “Chang’e running to the moon”. According to the legend of

,

,

and

, Hou Yi and Chang’e were gods and men in the era of Emperor Yao. At that time, the emperor of heaven had ten sons, who took turns to shine as the sun on the earth. One day, due to neglect, ten suns slipped out together and appeared in the sky at the same time. The earth was scorched and the crops dried up. People were out of breath and fell unconscious on the ground. Because of the extremely hot weather, some strange birds and beasts also ran out of the dry Jianghu and the flaming forest, killing people everywhere.

the emperor of heaven was shocked and very angry. He ordered Hou Yi, who was good at archery, to discipline his son on earth. Hou Yi took a red bow and a bag of white arrows given to him by the Heavenly Emperor

and came to the world with his beautiful wife Chang’e. Originally, the emperor of heaven just wanted Hou Yi to frighten his son. Unexpectedly, Hou Yi was furious when he saw the suffering of the world, and shot at the sun one by one. In an instant, nine of the ten suns were shot. Fortunately, Hou Yi was held by someone, and the last one was saved. The last sun dared not act recklessly and did his own work conscientiously.

Hou Yi made great contributions to the people, but killed nine sons of the emperor of heaven. Coupled with the slander of the God who contributed to the credit of Christ Hou Yi, the emperor of heaven finally denounced Hou Yi to the world forever. Hou Yi and his wife Chang’e had to live in seclusion and make a living by hunting.

Hou Yi felt sorry for his wife who was relegated to the world because of his involvement, so he went to the queen mother of the west to ask for some elixir of immortality, so that he could live in love with Chang’e forever in the world. Take one of these elixirs and you can live forever. Take two and you can fly to heaven again. Chang’e couldn’t get used to human life. In the absence of Hou Yi, she stole all the elixirs of immortality. As a result, she flew too far and even flew into the moon.

what many people don’t know is that Hou Yi really existed in history, and this Hou Yi was still the king of the state of Xu, and his wife’s name was indeed Chang’e.

after Xia Qi died, his son Taikang ascended the throne. Taikang is a very fatuous monarch. He doesn’t care about politics and loves hunting. Once, Taikang took his entourage to the South Bank of Luoshui to hunt. He fought harder and harder,I haven’t been home for a hundred days.

at that time, Hou Yi in the lower reaches of the Yellow River became king Xu. He was ambitious and wanted to seize the power of King Xia. When he saw Taikang go hunting, he thought it was an opportunity, so he personally led the troops to guard the North Bank of Luoshui. When Taikang came back happily with a large number of hunted wild animals, he went to Luoshui and found that the opposite bank was full of Hou Yi’s army, and the way of return was cut off. Taikang had no choice but to live in exile in the south of Luoshui. Although

,

,

forced Taikang to have a country and a home, and he controlled the power of the Xia Dynasty, Hou Yi was afraid of the opposition of the world and did not dare to establish himself as king. He also established Taikang’s brother Zhongkang as the king of the Xia Dynasty, acting as a puppet and holding real power by himself.

Hou Yi was just an assistant to Zhongkang at first. But Zhongkang died early. As soon as Zhongkang died, Hou Yi became more unscrupulous. He simply drove away Zhongkang’s son Xiang and took the throne of the Xia Dynasty.

Hou Yi, who has become the new generation of Xia king, is far from being a wise, powerful and kind-hearted man in myths and legends. He was not only extravagant and desperate, trying to squeeze the people, but also relying on his archery skills, he hunted everywhere like Taikang, and handed over the state affairs to his confidant Han Zhuo. Han Zhuo is also an ambitious man. He bought people’s hearts without telling Hou Yi. When he had full wings, he sent someone to kill Hou Yi when he returned from hunting.

Han Zhuo killed Hou Yi and took the throne. Afraid that Xia Qi’s descendants would compete with him, he sent people everywhere to hunt down Xiang, the son of Zhongkang. Where to escape, before long, Han Zhuo’s pursuers will come with their tails. Later, Xiang was finally caught and killed by Han Zhuo. At that time, Xiang’s wife was pregnant. After being chased and killed by Han Zhuo, she climbed out of the hole in the wall and fled to her mother’s house. There were

and

. She still had a surname and gave birth to a son named Shaokang. When Shaokang grew up, he looked at animals for Youshang tribe. Han Zhuo didn’t know where to find out that a posthumous son of Xiang was still alive. He immediately sent troops to recover him. Shaokang got the news that Han Zhuo sent someone to hunt him down and immediately fled to the descendants of Shun Youyu.

Shaokang grew up in a difficult environment and practiced his skills. With the support of the Youyu family, he recruited troops and horses there and formed his own army. Later, with the help of ministers and tribes loyal to the Xia Dynasty, he finally began to counter attack Han Zhuo. Han Zhuo was not a capable ruler and was soon defeated by Shaokang. Shaokang finally regained the throne.

in the Xia Dynasty, from Taikang to Shaokang, it took about a hundred years of scuffle to recover. In history, it is called “Zhongxing of Shaokang”.

Han Zhuo was eliminated by Shaokang. It can be seen that the struggle between the Dongyi nationality led by Xu and the Xia Dynasty is not over. The Dongyi people have many famous archers with excellent bows and arrows and superb shooting skills. Later, after Shaokang’s son Shu ascended the throne, he invented a body armor that can avoid arrows, called “armour”. With this kind of armor, the Xia Dynasty defeated the Yi nationality, and the prosperity of the state of Xu in the Xia Dynasty ended.

as early as the era of Yao, Shun and Yu, Daye, the descendant of SHAOHAO, was given the surname Ying by Emperor Shun to Boye, the son of Daye, because he helped Dayu to control the flood. Boyisheng has two sons, one is Dalian and the other is Ruomu. Among them, Ruomu was sealed by Xia Qifeng in the “Xu” country. During the Xia Dynasty, the state of Xu fought against the Xia Dynasty. In the Yin, Shang and spring and Autumn Periods, the state of Xu was still a relatively powerful vassal state, and there were frictions with Zhou and other vassal states. Later, the throne passed to King Xu Yan.

King Xu Yan, born in the 36th year of King Zhao of Zhou, is famous for his birthday and his full name is Ying birthday. According to historical records, King Xu Yan “was born without crack, thought it was ominous and abandoned the waterfront”. In other words, when he was born, his tunic was not broken, like a meat ball. Therefore, his family hated him and thought it was an ominous thing, so they abandoned him. This experience is a little similar to Nezha. According to myths and legends, Nezha was also a meat ball when he was born, probably because his tunic was not broken.

there is an old woman named Dugu who keeps a dog named “hucang”. She always likes to walk around looking for food and often catches some pheasants and rabbits to bring back to her. The dog found the abandoned King Xu Yan and took him home. The old woman saw that the dog took back a meat ball, and there was something crawling in it. It was very strange. When she cut it open, she got a baby. The description was correct and the cry was loud, but her two small hands held tightly. When the old woman broke it apart, there was a complex texture on the baby’s left and right hands, like two words. Later, someone told the old woman that these two words, one is “Yan” and the other is “Wang”. When the child grows up, he will be king Xu Yan. According to the old records of Sihong in the state of Xu, when the dog “hucang” who saved the king of Yan died, “the head had horns and nine tails, and covered with yellow dragons. There were ridges in the Xuli where he was buried”, which was called “longdun”. The site is now located in Chengan Township, Sihong County.

after the birth of King Xu Yan, according to the “corpse” records, “there are tendons but no bones”, probably because the flexibility of the body is better,

is like no bones. He was very adventurous since childhood. “He likes to get strange fish in deep water and monsters in deep mountains.” In Xunzi%26amp; #8226; Feixiang, it is said: “Xu Yan is like a king, and his eyes can see the horse.” It means that King Xu Yan’s eyes are big, which can be compared with horse’s eyes. Moreover, it is also recorded in the chronicles that “Wang Sheng has different appearances. His eyes can’t be seen in detail, but he can see in the distance”. It can be seen that King Xu Yan may have hyperopia and hyperthyroidism. At the age of 17, King Xu Yan was full of poetry and books. At the age of 20, he didn’t know how to recognize his family and inherited the throne of King Xu. After succeeding to the throne, King Xu Yan exercised benevolent government in the state of Xu, and was, the more we arrive. Finally settled in Zhoushan Islands. Now there are many King Xu Yan temples on Zhoushan Islands. According to the records of the four Ming Dynasties in Baoqing, Song Dynasty once salvaged

in Zhoushan. A solid bronze tripod without feet was produced, which proved to be the relic of King Xu Yan. In addition, there are still many place names on Zhoushan Islands, which are named after the word “Sizhou”. Such as “Sijiao mountain”, “Sizhou pond”, “Sizhou Ao” and so on. There are also some places dedicated to Sizhou great emperor temple. Si here refers to the former capital of King Xu Yan.

Xu surname is not uncommon in Chinese surnames. The word “Xu” appeared as a name earlier than the state of Xu. Before the Dayu era, there may have been Xu — Xuzhou was among them when Dayu divided the world into Kyushu Island. It was also verified that the division of Kyushu by Dayu was not initiated by him, but followed the twelve states divided by Shun. In this way, the name “Xu” comes from earlier.

,

,

and

in oracle bone inscriptions, some people have verified that it is the original appearance of the word “Xu”. From Yu to Xu, after many changes, either add “soil”, or add “wood”, or add “water”, or add “grain”. These changes show that the ancient Xu people lived by the water, had houses and cities, and knew how to reclaim land and plant rice and wheat. It can be seen that “Xu” has a very long history.

the surname Xu is the descendant of Xu people, which is beyond doubt. However, the descendants of Boyi probably did not immediately take the state as their surname. Their surname is Xu, which should be after 985 BC (the 17th year of King Mu of Zhou). Although the surname Xu has an ancient origin of 4200 years, the real history of the surname Xu among Chinese people is about 3000 years.

,

,

,

the surname Xu is the same as the surname Huang. They are all descendants of Bo Yi, the leader of the Dongyi tribe.

Boyi, also known as Dafei and Boyi, is said to be good at animal husbandry and hunting. Boyi is the eighth grandson of the Xuanyuan family of the Yellow Emperor. It comes from the Zhuanxu Gaoyang family and was once the leader of fire for Yao and shun, “Break mountains and rivers and burn, and animals flee and hide “, he adopted the policy of burning mountains and hunting birds and animals that escaped, which solved the most urgent problem of food for the people at that time. He also helped Xia Yu control the flood, so Yu Shun gave him the surname Ying. Xia Yu received Zen and once took Boyi as his face. Before he died, he decided to give up the throne to him. Keboyi saw that Yu’s son Qi was young and wise, insisted on giving up his position, and only took photos of political affairs for three years during Qi’s funeral, until he died Man immediately left and went to the south of Jishan (in today’s Henan Province) to live in seclusion. After Xia Qi ascended the throne, he felt the high righteousness of Bo Yi’s seclusion and sealed Bo Yi’s second son Ruomu in the state of Xu, which is now North of Si county, Anhui Province. Since then, Boyi’s descendants have multiplied here from generation to generation. It was not until the early years of the Western Zhou Dynasty that the state of Chu sent by King Mu of Zhou to attack was destroyed because of the “arrogation of King Xu Yan, the monarch”.

after the state of Xu was destroyed, King Mu of Zhou didn’t kill all of them, and granted the son of King Xu Yan Zong as the son of Xu. Of course, from the throne to Viscount, the status of the state of Xu has plummeted. From this time on, some descendants of the state of Xu took the state as their surname and took Xu as their surname because of the pain of losing their country or lack of proper resettlement. At that time, the surname “spekds” was not the only descendant of “spekds”, but “spekds”. According to the historical records,

Xu’s son at the time of the subjugation of the state of Xu was Zhang Yu, the 11th grandson of Zong, the 12th grandson of King Xuyan and the 44th grandson of Boyi, The 52nd grandson of the Yellow Emperor. It was once suspected that although the ancient state of Xu was established early, its territory was small. After the Xia, Shang and early Zhou dynasties, it was always limited to Sixian County in Anhui Province. Sixian county is far away from Wuhan. How could the descendants of the state of Xu go there to develop?

when Tu Yan was king, the state of Xu was the most powerful. Its power once developed North to the south of Shandong and the north of Jiangsu, and the south to the middle of Anhui and the east of Zhejiang. Therefore, Dongshan mountain in Wuyuan, Tongshan County, Jiangsu Province, was named Xushan because King Xu Yan had been there. Dinghai, Zhejiang, also had the place name of tuiyan King City in the past. Under the pressure of the Chu army, it is also natural for some people in the state of Xu to settle in the South and seek development.

the area in southern Shandong and Northern Jiangsu belonged to Donghai County at that time when the county system was implemented in the Han Dynasty. For thousands of years, the family surnamed Xu has expressed its origin and origin with “Donghai”. Donghai is a county name that appeared in the early Han Dynasty, including the place from the east of Pixian County in Jiangsu Province to the sea and Ziyang County in Shandong Province to the sea. The county is governed in the southwest of Tancheng County in Shandong Province.

simply put, the lineage of the surname Xu is as follows: the first ancestor, the Yellow Emperor; The second ancestor Changyi; The third ancestor, Zhuanxu Gaoyang; The fourth ancestor was Zhongrong, one of the “eight alders”; Fifth generation ancestor Yi; The sixth ancestor Wu Heng; Bo Xin, the seventh ancestor; Eight generations of Zugao pottery, No. Daye; Ninth ancestor Boyi; Ruomu, the tenth ancestor, was granted the state of Xu in the early summer. This is the ancestor of the surname Xu. In addition, Ruomu’s elder brother Dalian is the ancestor of Qin, Zhao and other surnames; His brother en Cheng is the ancestor of the Jiang family.

however, Boyi’s descendants are not only one surnamed Xu. According to the records of Qin Benji, Boyi’s surname is Ying, and there are 14 surnames derived from Ying, That is: “before the Qin Dynasty, it was the surname Ying; after that, it was enfeoffed and took the state as the surname: Xu, Ju, Tan, Zhongli (i.e. Zhongli), Yunyan, tuqiu, Jiangliang, Huang, Jiang, Xiuyu, Baiming, feiliannian and Qin. However, after the Qin Dynasty, the father granted Zhaocheng as the surname Zhao.” Therefore, there are many “homologous and different surnames” of the surname Xu.

in 2170 BC (the sixth year of Xia Qi), Xia Qi killed Bo Yi and granted Ruomu, the second son of Bo Yi, to Xu, and the state of Xu was born.

during Taikang, Hou Yi, the king of the state of Xu, chased Taikang and established Zhongkang. After Zhongkang died, he became king again and was finally killed and usurped by his confidant Han Zhuo. Later, Shaokang, the son of Zhongkang, rose to defeat the Dongyi group and regain the throne.

in 996 BC (the sixth year of King Mu of Zhou), King Xu Yan led the eastern princes to calm down the chaos and made meritorious contributions, and was granted the title of Bo by the son of Zhou.

in 963 BC (the 13th to 17th year of King Mu of Zhou), King Mu of Zhou ordered the state of Chu to raise troops to attack Xu. King Xu Yan abandoned his country and fled. He was finally oppressed by the pursuit of soldiers and died in the sea. Zhou granted Baozong, the second son of King Xu Yan, a knight, set the capital Pengcheng and continued to govern the state of Xu.

in the winter of 512 BC (the eighth year of King Zhou Jing), the state of Wu attacked Xu and flooded the state of Xu. Zhang Yu, king of Xu, fled to the state of Chu, and the state of Xu lost its name since then.
