At that time, nobles had surnames, surnames, names, characters and different usages. The reason why we say nobility is because ordinary people have no surnames and surnames, only first names. According to the rules at that time, men can only call him by his last name, not by his last name. And "Ji" is the surname of King Wu, so we must not call him, but should call him by his surname.
What is Zhou Wuwang's last name? In the Qing Dynasty, Gu said in "The Original Surname": "The noble is the monarch, and the monarch has no surname, so he does not call his surname the country. The second is a son, who has no surname and is not called a son. The bottom person is Shu Ren, and Shu Ren has no surname and does not call him by his first name. " Therefore, we can draw the conclusion that King Wu has no surname. The name of the country is Zhou. Then what do you call him?
Let's look at the historical records and see what people called his brother at that time. Yi * * * is the brother of 10. The boss is Bo Yi Kao, Kao is his name. According to the order of "uncle Ji", the boss is uncle. This city is his official position. Therefore, he is called "Bo Yi Kao". Zhou Wuwang is the second child. From the third child to Laojiu, they are all called uncles. Old five fresh, old five Cai Shudu, old six Cao duo. Lao Qi Wu, Lao Ba Huo Shu Chu, Wei Kang Shu. Lao Shi is the youngest one, so he used the season, so he was called Ran Jizai. As can be seen from the above address, the first word they address is the country name of their country, and all of them take the country name as their surname. When a man calls his family name, the first word is his country name. So it's called: surname+ranking+first name.
Because he has no surname, he should be called "Prince" or "Da Zi" before adulthood, and people will call him "Prince Fa" or "Da Zi Fa". After Zhou Wuwang succeeded to the throne, he became a monarch. The monarch is called Guo, and the title of the Western Zhou Dynasty is Zhou, so it can be called. However, you may ask, "King Wu" is not posthumous title, and it is impossible to use posthumous title after his death. In fact, "King Wu" was not his posthumous title, and posthumous title only appeared in the middle of the Western Zhou Dynasty. "King Wu" was the name he gave himself before his death. So, what should I call him? Zhou Wuwang has no surname and is called the country. He ranks second, especially Zhong, so he should be called ",,"or ".
After Qin and Han Dynasties, surnames merged, and many people didn't know the difference between surnames and surnames, so some people called him "Ji Fa". Accordingly, the old four Zhou Gongdan can't be called Ji Dan, but should be called his uncle. Because he is the Duke of Zhou, people usually call him Zhou Gongdan. Similarly, Qin is Zhao and won the surname, so Qin Shihuang should be called, not Ying Zheng. Historical records and earlier documents all called Qin Shihuang Zhao Zheng or Qin Zheng, but there was never Ying Zheng.
