Everyone has their own name. Strictly speaking, it's the name. Chinese names are usually one or two characters (of course there are still three, four or more), preceded by the surname passed down by one's ancestors. This is the complete and most common name. Surnames are left by our ancestors. Why did our ancestors add such pronunciation or glyph characteristics to their own names very early on? There are many interesting or slightly strange surnames, such as animal surnames such as Niu, Horse, and Fish, temperature surnames such as Leng, Wen, and compound surnames such as Linghu, Sima, Ouyang, Ximen, etc. So what does Linghu mean? Literally understood, it seems to be able to direct the fox to do whatever. Of course, this explanation is concise and unsatisfactory. Most of the surnames cannot be explained in Chinese, so they can only be one kind of surname. But this is also the same as explaining the cause itself. A person's name seems to have nothing to do with the person's destiny and character. Only in some novels, in order to reflect some characteristics of the characters, novelists choose some more literary names to facilitate readers' impression. So, is the name just a code name? In the words of a philosopher, what happens after it is removed? Are there any surprising discoveries if you delve deeper? Would a name be the most mundane human gift in the universe? Or is it the most dialectical trace of chance and necessity intertwined?
