The Chinese nation has been passed down for "five thousand years", during which different "surnames" have been born for various reasons, and there are still "Hundred Family Names" passed down; of course, the so-called "Hundred Family Names" does not mean that there are just 100 surnames, such as "Zhang Wang Li Zhao" intermarried for generations, which gave birth to the current 1.4 billion Chinese sons and daughters. Speaking of "intermarriage between generations" is more interesting, there is a saying of "yin and yang reconciliation" in ancient times, and the blunt explanation is that "there is yin and yang, and there is yang and yin"; it seems that the same reason, since there is a "generational intermarriage", there is a surname of "intermarriage for generations" in history.
According to today's census statistics, in the Wuhu and Anqing areas of Anhui Province, there is a surname ethnic group with a population of about 120,000 or so; of course, some friends may think that the surname is a bit weird, but it is understandable, after all, each surname has its own historical origin. The two surnames of "Cao" and "Cao" are typical examples, and the rules of "non-intermarriage" between the two ethnic groups even date back more than 1,000 years; speaking of this, a friend may ask "Is there any hatred between these two surnames?" Even if there is, it will be time to put it down in more than 1,000 years. ”
It is funny to say that "Cao surname" and "Cao surname" are not only not hateful, in a sense, these two surnames are still relatives; to answer the question of "Cao and Cao are not married", a smart friend may have guessed that the cause is "Cao Cao". Friends who have studied history may have a deep understanding of "Cao Cao", who can be described as a "traitor" at the end of the Han Dynasty, who won two of the three worlds, who was undefeated in civil wars with Sun Liu and unyielding in the external resistance to the Xiongnu; of course, although "Cao Cao" dominated the world, he did not become emperor, or his son "Cao Pi" usurped the throne, which established Cao Cao as the "founding ancestor".
Here is only a brief introduction, there are many friends who have studied the "Three Kingdoms," and there are not many details. In short, although "Cao Pi" became emperor, who knew that there was another "Sima Yi", and Jiangshan changed hands again, that is, the "Jin" in history; from a certain point of view, the "Sima" people stole the "Cao" surname to establish jiangshan for several generations, and the people of the world have quite a word about this, and even the "Sima " people feel that they are at a loss. In order to block the mouths of the Yoyo people, and to prevent the "Cao surname" from counterattacking, like at the beginning of other dynasties, the "Sima" people used their power to raise a butcher knife against the "Cao" people.
According to "legend", at that time, Cao Cao's descendants flourished, and many people were also divided into various places to become the kings of the domain, so that the "Cao surname" multiplied and distributed in a wider area; after the "Sima " people carried out the great purge, many of the "Cao surnames" that were already distributed everywhere fled to various places, so the distribution area was wider, and the "Sima" people did not destroy Cao Cao in the end; besides, the "Cao" surname, the origin was also Cao Cao, "legend" Cao Cao's descendants, one of the people named Cao Lin, was deeply affected by the Sima people, and led his clan to flee to southern Anhui.
In order to avoid disaster, Cao Lin came up with the trick of "changing his surname". But the ancients were very taboo, ancient there is "sitting can not change the name, do not change the surname", not to mention that the Cao surname was once a noble royal family, the family name glory can not be lost; Cao Lin thought about it, and finally remembered the ancestor "Cao Cao", carefully look at the words "Cao" and "Cao" are originally harmonious, so decided to change the surname "Cao", as if this can retain the glory of the past. In any case, Cao Lin eventually changed his surname to "Cao", which was inherited by generations of descendants, and at the same time there was this historical origin that was passed down; the latter was logical, "Cao and Cao" were originally from the same lineage, and it seemed reasonable that close relatives did not marry.
Here it needs to be emphasized that the origin of the surname is only a legend, and the unmarried of the two ethnic groups actually has no practical basis. "Cao" surname, its history is far more than the Eastern Han Dynasty, and even back to more than 3,000 years ago in the Yin Shang era, its ethnic distribution is not limited to Anhui, in the present-day Zhejiang, Shanghai, Hubei, Jiangxi, Henan, Sichuan, Guizhou, Guangdong, Guangxi and other regions have Cao surname descendants; of course, due to the long age, the origin of the "Cao" surname is also controversial, one of the generation of monarchs "Pan Geng" once crowned his own scholar, so the "Cao" surname was originally an official name.
Another said that "Cao" originated from the imperial family Ji surname of the Western Zhou Dynasty, or a descendant of the King of Zhou Wu "Ji Fa", generally referring to a professional skill name at that time; according to today's archaeological investigation, experts found the "Cao Clan Genealogy" in Poyang, according to the records here, the "Cao" surname originated from the Southern and Northern Dynasties era, and the ancestor was "Tiancheng Gong". Later, experts have verified that the so-called "Tiancheng Gong" was a rebel leader during the Southern and Northern Dynasties, the prototype was Emperor Min of Liang; of course, the folklore "Cao surname originated from Cao Cao" is also included in the research, and the research results of the joint topic of history and anthropology of Fudan University show that the "Cao surname" is not a descendant of Cao Cao.
This makes it very clear that "Cao and Cao" are not directly related, and "Cao and Cao do not marry" is just a legend and story made up by the people.
