I personally am certain that stuff about two months' holiday and (official) two hour lunches is untrue, or applies only to a very small fraction of the population. Certainly it does not apply to workers in foreign-owned enterprises. I have never, ever heard any person mention 'two month holidays in China' and I live in Hong Kong - I would have heard someone mention it by now, if it were widely applicable (cos we only get two weeks). So you don't need to add the word 'perceived' to your comment.
