Hi ChinesePod team, my question is this: I ran across this phrase the other day and I don’t think I understand it’s full meaning. I think it means something like…
To use a Western example 
Can someone confirm, or explain if I’m off the mark?
Ah I love that you’re using Jim Halpert as the example, as he absolutely captures the meaning of the expression!
Depending on the context, it can have different meanings, but basically, it means that there are no words to describe my emotion and it’s better if I gave you a look and you try to figure it out yourself. That emotion can be disappointed, speechless, or anger etc and you have to decipher it yourself.
Warmly,
