Is Angel a good English name?

Haha, it depends on where you use it. It doesn't matter in China, but you will be laughed at by others abroad. Just like if you have a friend whose real Chinese name is Angel, wouldn't you feel weird?

But Angel

The meaning of this name is quite good, it sounds good, it’s okay, anyway, don’t call it like my friend

Titty (I don’t know the meaning) Just check it yourself), hahahaha
