Really!  Sounds a lot like Mandarin bai-passive (which except in
modern translationese always means something the Patient doesn't
want to happen...)


Hmm... The bai-passive sounds like it corresponds to the use
of /bei35/ in Cantonese, and I can think of many examples there where
the action towards the patient is not beneficial...

/go33 lam21 jAn35 bei35 go33 gAu35 NAu35 dou13/
The man was bitten by the dog.

For some reason, it sounds more emphatic than:

/gAu35 NAu35 dou13 go33 lam21 jAn35/
The dog bit the man.
