As early as the Warring States period, there was a special tribe living in the north of our country, they had no writing, no fixed city, and lived by water and grass. The Chronicle of History says that they were descendants of the Miao clan of the Zuxia Hou clan, while the Genealogy of the Lands says that they were descendants of Xia Jie's son, The Gerry, and the Chinese call them Xiongnu.
At about the same time that Qin Shi Huang unified the Six Kingdoms, the Xiongnu in the north also began their own unification path, and they successively annexed many tribes such as Ghost Fang, Tufang, Inu rong, Lin Hu, etc., and established a unified slave empire, controlling more than 300,000 people. After that, taking advantage of the weakness of the Western Han Dynasty, the Xiongnu repeatedly went south to rob property and plunder the Han Dynasty population as slaves for the nobles.

After decades of inactivity, the Western Han Dynasty's national strength was restored, and Emperor Wu of the Han Dynasty officially launched a war against the Xiongnu. Thanks to the wise hero of Emperor Wu of Han, a military genius Wei Qing was discovered from among the riding slaves, and then another genius general, Huo Qi, was found to be ill.
In the second year of the Yuan Dynasty, huo went to the sick officer at the age of 19 to pay homage to the general of the hussars, and set out from Longxi with more than 10,000 cavalry, all the way to the wild, this fight actually broke into the Yanzhi Mountain thousands of miles away, defeated the Xiongnu Hun Evil King and the Hu Tu King, and also took away the Sacrifice Heavenly Jin people of the Hu Tu King.
Because of the loss of the river loop, the Xiongnu single-handedly wanted to kill the Hun Evil King in anger. The Hun Evil King, who received the news, was horrified and hurriedly pulled King Xiu Tu to surrender to the Han Dynasty. However, when he reached the middle of the road, King Hun Tu repented, he thought that the Hun Evil King had suffered heavy losses, and he had only lost the Sacrifice Heavenly Golden Man, so he would not be killed, so he wanted to turn back, but the Hun Evil King had already made preparations, and joined forces with Huo to kill him.
In recognition of his exploits, Emperor Wu of han poured out his treasury to reward the Hun Evil King, but suppressed the people of King Xiu Tu who were forced to surrender, and King Xiu Tu's Fu clan and two princes under the age of 14 were taken into the court as slaves to show humiliation and punishment.
By chance, when Emperor Wudi of Han was entertaining at the court one day, he accidentally met a Xiongnu teenager who was responsible for raising horses, and upon careful questioning, he learned that it was the prince of the former King Of Hutu, and because Huo Wentai had taken the sacrifice of Tianjin from their tribe, Emperor Wudi of Han casually gave him the surname Jin and the name Riju. Since then, Jin Ilju has become the name of the Xiongnu prince, and as for his Xiongnu real name, no one remembers.
Because of his loyalty and reliability, Jin Ilju leapt from a former slave to a Guanglu doctor, and after the death of Emperor Wu of Han, he became the four major ministers of Emperor Zhao of Han, and since then, the Jin Ilju family has risen, and the seven dynasties of Emperor Wu, Emperor Zhao, Emperor Xuan, Emperor Yuan, Emperor Cheng, Emperor Lai, and Emperor Ping have flourished for a long time.
Until the end of the Eastern Han Dynasty, when the Han Dynasty was in danger, Jin Yi, a descendant of Jin Ribao, remained loyal to the Han Dynasty and launched the Xuchang Mutiny in an attempt to kill Cao Cao, and as a result, the matter was revealed and killed. After the fall of the Han Dynasty, the Jin family did not decline with it, but flourished. By the time of the Ming Dynasty, the descendants of the Jin clan had spread all over Jiangxi, Zhejiang, and Jiangsu, and even the Cong surname of Shandong was also a descendant of Jin Ribao, which could be described as a list of Yibu stars, which was difficult to count.
Not only that, but there are also descendants of Kim Il-seok overseas. When Liu Xiu established the Eastern Han Dynasty, members of the Kim Il-ri family who had been related to Wang Mang fled to the Korean Peninsula because they were worried about being implicated, and from then on brought the surname "Jin" to the peninsula, and later mixed with the royal family. According to the "Monument to the Tomb of King Wenmu of Silla", the 30th king of Silla, Kim Famin, is a descendant of Kim Il-seok.
By the 19th century, the Kim population had a blowout on the peninsula. Why is that? It turned out that in 1894, the King of Korea officially issued a decree allowing ordinary civilians to have their own surnames. At that time, when the commoners chose their surnames, they all chose the former royal surname to paste gold, and Jin was once a Silla surname, so there were more and more people with the surname Of Jin.
To this day, the Kim surname is a big surname on the peninsula, and there are hereditary families in the north, which gives the United States a headache.
