Possesive, shrink.

I’ve had a doubt with the apostrophes lately, how should it be:

The chinese’s guy bike or the chinese guy’s bike

The other thing is that I was watching a TV show with english audio and spanish subtitles so I heard something like “you should see a SHRINK” but Im not sure if shrink is what he said and on the subtitles it was “psychiatrist”.

  1. “the chinese guy’s bike” is correct.
  2. A shrink is a slang word for psychiatrist, it derives from “headshinker”. The use of “shrink” is very common, at least in the States.

Thanks! nice answer.
