Well, let me pitch in, if I may.

We all know you are an authority on chinese culture, and very fluent in Chinese language.

But I have been here near enough 8 years now, and well, I also consider myself a zhong guo tong.

Guesstimates are the way things are done here. Environmental survey, just make up round numbers that will please your boss.

Accounting? As long as it looks good and pleasing, mei banfa.

See what I am getting at, good doctor? Again, nothing PERSONAL intended, from a non-doctor.
