While I don't want to seem unappreciative, I'm asking about the *etymology* of 背后.  It's surprising that both its literal and figurative meanings match those in English.

@Becky 李蓓 When something happened behind one's back, that person cannot see it. It is logical to use it  figuratively for  "place you cannot see = instances unknown to you" which I have stated in my answer . It is true in all language, including English

Don't think you mean the etymology. Ask Drooze about that! 背 bei has something to do with facing south and 后 is a person giving orders. Tang Ho is right.  Why does it surprise you that “behind my back" has this meaning in Chinese? People are people! 你不要在背后捣鬼！

@Pedroski “etymology” is correct, we try to use [tag:glyph-origin] for graphical origins of characters.

<p>Yes, 背後 can mean did somethings without your knowledge or secretly. For example, 小心他可能在背後捅你一刀。 (Watch out, he may backstab you.) In this example 在背後捅你一刀 shared similar meaning of backstab. And it is one of usage of 背後, it means did somethings without your knowledge or secretly. While 捅你一刀 stands for harm you.</p>
