The word Wang first gives people a feeling of high-end atmosphere, because in ancient times, people with status and status were called Wang. Wang Zi is also called "Yu Bu" in Chinese character structure, and many characters related to the meaning of jade are beside Wang Zi. In fact, from the form of the word "jade", we can see that it is a typical "representation" Chinese character. "Wang" means a person who is a king and an official, and that point is emphasized as something around his waist.
Moreover, in ancient times, the words "Wang" and "Yu" were common, but when writing radical, this point was omitted because the space of the last stroke was too small compared with that after becoming "Ti", which was difficult to write on the one hand and inconvenient to write on the other.
Therefore, in fact, from the perspective of word creation, the side of Wang Zi itself is the side of Yu Zi, which is called "Jade Supplement" because some points are omitted.
It turns out that the radical of the word Wang is the abbreviation of jade. If you have a friend surnamed Wang around you, you can say that his surname was originally Yu next time.
