The source of Xu's surname is relatively pure, mainly from the won surname. He is a descendant of Ruomu, the son of Boyi, the great grandson of the first emperor. According to legend, the trapped emperor had a granddaughter named Nvxiu. She had a great career because she ate swallow eggs. Daye married a young woman named Hua and gave birth to Boyi. Boyi actively assisted Dayu in water control. Apart from officially changing his surname to Won, Shundi married his own local woman Yao, and later gave birth to two sons, the youngest of whom was Ruomu. Because of his father's meritorious service, he was named Xu and established Xu Guo. After Xia, Shang and Zhou Dynasties, Xu existed as a vassal. Zhou Muwang's era spread to Xu Junyan, and he was the 32nd grandson of Xu Guo. He is very clever and friendly to the people, so he is deeply loved by the people and his national strength is getting stronger and stronger. At that time, Zhou Muwang liked to travel around the world and often didn't ask about state affairs. The governors complained a lot about him, so Xu Junyan had ambitions to replace Zhou Muwang. So he claimed to be Xu Yanwang and led the allied forces of various countries to March on Zhou. When Zhou Muwang learned the news, he immediately returned to Beijing and transferred troops to suppress it. Xu Yanwang had to retreat and escape. He hid in the mountains near Pengcheng. Because of his popularity, many people followed him to the mountains. This mountain was later called Xushan, hence the name Xuzhou. Therefore, he had to seal his son to live in Xu, called "Xu Zi", and continue to manage Xu. During the Spring and Autumn Period, Xu was defeated by Chu, and his national strength gradually declined. In the eighth year of Zhou Dynasty, Xu was destroyed by Wu, and Xu's descendants called Xu, taking the country as their surname, and passed it down from generation to generation.

There is another saying:

According to legend, Ruomu, the son of Boyi in Xiafeng, was born in Sixian County, Anhui Province, and Guo Xu was a vassal in Xia, Shang and Wednesday. Zhou Muwang has Xu Junyan from time to time. He is clever and kind, and has won the support of the people. His national strength is growing. At that time, Zhou Muwang liked to travel around the world, often for several years. No one was in charge of state affairs, and many local governors complained. Later, when Xu Junyan was digging a river, he dug up a pair of red bows and arrows. He thought it was a godsend and suddenly had the ambition to replace Zhou as the son of heaven. The surrounding governors heard that he had bows and arrows, and they all came to join him, so he called himself Xu Yanwang and led 36 allied forces to attack Zhoudu. At this time, Zhou Muwang is visiting the Queen Mother of the West on Kunlun Mountain. After he got the news, he set out overnight, drove through Zaofu, traveled thousands of miles a day, returned to Zhoudu, and set up an army to suppress it. Xu Yanwang didn't expect Zhou Muwang to come back so soon. Seeing that a bloody battle was about to happen, he sized up the situation and could not bear to let the lives of the people pass away. He bravely retreated, abandoned his country and fled, hiding in the mountains around Pengcheng (now Xuzhou). Because of his popularity, thousands of people followed him into the mountains. This mountain was later called Xushan, hence the name Xuzhou. Seeing that it was very popular in the local area, he named his descendants and continued to manage Xu. In 5 12 BC, the state of Xu was destroyed by the state of Wu, and descendants called it Xu, which is the origin of Xu. According to the examination, the Xu family lived in Donghai County (now southeast of Yanzhou Prefecture, Shandong Province)
