China's most embarrassing surname, whatever it is called, is a joke.

Fuck, this surname is rare in China's surname. There are many stories about the origin of Cao Shi in history. One of the most convincing and credible stories is that Cao's surname originated from Cao's surname in the late Eastern Han Dynasty, or more accurately, Cao's surname should be a descendant of Cao. It is said that after the establishment of the Western Jin Dynasty, Cao's descendants began to persecute a large number of Cao's descendants in order to consolidate their political power. In order to avoid Si Mazhao's pursuit, all the way from the Central Plains to Poyang County, Jiangxi Province today, Cao Cao's descendants changed their names and surnames to Cao Cao for fear that their identity would be exposed. Therefore, there has been a folk custom that Cao Cao and Cao Cao cannot marry each other, because they are originally a family.

Because the word Cao has indecent meaning in Chinese, it is too difficult to name it, and it is not nice to name it. So in the following hundreds of years, many descendants of Cao surname changed back to the original Cao surname. Now people surnamed Cao mainly live in Jiangxi, Anhui and other places, but the number is less than 1000. Although Cao's population is small, there is still a famous figure in modern China, that is, Cao Zhenqiu, a famous educator in China, which is also a comfort.

Many surnames in China are extremely rare, and some people have never heard of them. The most common is the surname in Hundred Family Names.
