I think there is a rare surname that is quite individual, but sometimes it is particularly helpless, because many people don't know that word, so it will be a bit embarrassing when others tell them that they don't know that word. Also, sometimes when people call themselves, they are skeptical, because they think they may be mistaken or something, and they think that no one is called by this name, so their tone is dubious.
It is said that it has a personality because rare surnames are not as popular as other surnames, and it is easier for others to remember themselves and leave a deep impression on others. I now have a college classmate named Pei. At that time, I didn't know the name of this word, so I deliberately asked others. At that time, she and I were a little embarrassed. I still remember when one of my high school classmates went to physical education class, the PE teacher didn't dare to call her name because the teacher didn't know the word.
Sometimes it makes others feel quite funny. The other day, I saw a man named "Dog Egg" in the connotation joke, which made me laugh at that time. In fact, any surname will do, and don't laugh at others for some reason.
