I don’t know if this is exactly a chope. It’s more a cute translation.
Long story, but about a decade ago I found myself in Vietnam with a dear friend of mine and his then-girlfriend (later-wife), who was from China. Her English was pretty basic in those days. Somehow the word “mermaid” came up, and she didn’t know it, so she looked it up in her English/Chinese dictionary.
“Oh, a beauty-fish!” she cried. Since then, I’ve only ever called a mermaid a “beauty-fish”.
