As for why we should compile Hundred Family Names, we should first understand that the author of Hundred Family Names is unknown. It is very likely that some unknown scholars were inspired by the inheritance and uniqueness of family names at that time.
This sentence was compiled by a scholar in Qiantang (now Hangzhou) in the Song Dynasty. At that time, surnames were only arranged in rhyming sentences with four words, which was easy to read, and no one deliberately made up hundreds of surnames. However, hundreds of surnames also reflected the status of surnames at that time. For example, the first "Zhao" is the national surname of the Song Dynasty, and "Qian, Sun and Li" are all the national surnames of the previous dynasties.
There are more than one hundred surnames in a hundred surnames. You should know that there are 568 words in this collection, including compound surnames, and hundreds of surnames are included, basically including all surnames at that time. No matter now or before, we have always had a strong sense of identity with surname culture. When you know someone, ask their last name first, then their first name. Therefore, Hundred Family Names reflects our traditional surname culture well.
