Stop being so arrogant.
There are narcissists everywhere. Some of them are so arrogant that they think they can ask for anything they want and give you the feeling as if they could fly. Well, we have a phrase that you can use to remind them of the meaning of “being modest”. So, how to say “Who do you think you are?” in Chinese?
Say “Who do you think you are?” in Chinese: 你咋不上天呢? (nǐ zǎ bù shàng tiān ne) = Who do you think you are?
咋 (zǎ): why
上天: (shàng tiān): fly to the sky
你咋不上天呢？(nǐ zǎ bù shàng tiān ne)
“Why don’t you fly to the sky?”
We use this phrase when somebody is asking for too much as a way to express incredulity.
