Is it possible to quip "My package went to Nanjing, but I'm in Beijing; that's the complete opposite Jing"? I'm trying to quip


  My package went to Nanjing, but I'm in Beijing; that's the complete opposite Jing.


For it to be funny in English, the reader would have to know that 京 in Nanjing 南京 and Beijing 北京 is the same, and the joke is a play on how 南 and 北 are opposites.

Here's my attempt at writing it, which is a fairly literal translation:


  我的快递发到了南京，但是我在北京。那儿是完全相反的“京”。


It's meant to be a joke.  However, I'm uncomfortable with the atypical grammar here.  I'm not sure it's even possible to express this in Chinese.

In speech, you can say: 我人在'北'京，快递却发到了'南'京. 

It would add some joking effect when you put a bit emphasis on 北 and 南. 

You don't have to say they are opposite literally. Your audience would seize that from your tone, which is the whole point of the joke.
