I am very experienced with nicknames.

I have had countless nicknames since I was a child. Usually, the nickname will be more memorable than your real name. When people start calling you by your nickname, you will rarely hear your real name.

Let me give an example, now my classmates call me hippo because they say I look like a hippo, but in fact many people don't think so, but they still call me, although I was a little unhappy at first, but now I It's been fine.

But if I want to use the name Hippo to be famous, I will definitely be reluctant, because although this name is very memorable, it is not very pleasant, and I would rather use my English name.

Even so, it's better not to give other people random nicknames, after all, others may not like it.
