The descendants of Yan huang have always been the self-designation of the Chinese, and the Yan huang here is the second yan emperor and the yellow emperor of the ancient Chinese period, and generally speaking, the ancestor refers to the two of them. But there was one person who was also one of the ancestors, and this person was Xuan You, who was different from the Yanhuang Emperor. If you are one of these four surnames, then you are most likely not a descendant of Yan Huang, because these four surnames are descendants of the Xuanyu clan.
Xuanyu was the leader of the Jiuli clan in ancient times, and it is said that he had eighty-one brothers, which means that there should be eighty-one tribes. Xuan You was originally a tribe with Emperor Yan, but later he came out independently and did it himself. It is said that Xuanyu's mount is an iron-eating beast, which is our national treasure today, and I didn't expect that such a soft and cute creature would be the mount of the god of war. Xuan You's strength was relatively strong among the three, and he also made outstanding contributions to the formation of china's early fame.
Nowadays, there are many sites related to Xuan you in Hebei Province, and myths and legends record that Xuan You has eight feet, three heads and six arms, and is almost invincible. At the beginning, he had a fight with Emperor Yan and defeated Emperor Yan, and then the Yellow Emperor felt that the young man Xuan You was a bit dangerous, so he agreed to join forces with Emperor Yan. There was a great war between them, a battle for deer.
This great war occurred about 4600 years ago, and the purpose of the war was to compete for the dominant Central Plains, and because of this great war, the idiom of chasing deer in the Central Plains was derived. This great war for the ancient Chinese people from the ancient times to the era of civilization, the impact is very significant. Relatively speaking, the weapons of the Xuanyu tribe were relatively advanced, and he already had the technology to smelt copper and iron. Therefore, at the beginning, the Yellow Emperor failed to defeat Xuan You, but the follow-up was mythological, and it is said that the Yellow Emperor had the help of a heavenly daughter to defeat Xuan You.
After the victory of the Huaxia clique, Xuan you was defeated, and the clans fled in all directions, so his descendants were all over the Han, Miao, Yao, and Qiang ethnic groups, and some of them were integrated into the Huaxia clique. And these four surnames are most likely descendants of Xuan You, the first of which is the surname Xuan. This surname is relatively rare, and according to the Minglun Compilation Clan Codex, this surname is a descendant of Xuan You.
Another is the surname Li, which is derived from their tribal name. The leaders of the Jiuli tribe to which Xuan You belonged, including Xuan You himself, were all surnamed Li, so this surname was actually very ancient. According to historical records, the state of Li, which was destroyed by King Wen of Zhou in the late Shang Dynasty, is a descendant of Jiu Li, which is recorded in folklore works. Moreover, the surname Li is the original surname of Xuan You, and it is more likely that this surname is his descendant.
The third is the surname Zou, which has a very large number of origins, one of which is the descendant of Xuan You. Nowadays, the surname Zou is also relatively large among the surnames of the descendants of Xuan You, and can be ranked sixty in the Chinese surname rankings. The population is also relatively large, with nearly 4.5 million people surnamed Zou in the contemporary era. Many of them are likely to be descendants of Xuan You, of course, some of the Zou surnames are also descendants of the Yellow Emperor.
The last one is the surname Tu, which is almost distributed throughout the country, and as many as 82% of zhejiang, Jiangsu, Anhui and Sichuan have this surname. One of them is derived from the surname Jiang, but it is a descendant of the Jiuli tribe Xuan you. This part is likely to have been included in the tribe, including the zou surname above, both of which were moved by the Yellow Emperor to the land of Zou Tu. After settling down, they took the land as their surname, so these two surnames also belonged to the descendants of Xuan You.
