From the experience with the Chinese teachers I had, they usually expect you to prepare the lessons in advance, so when they start a new lesson on the book you are expected to have already covered the new vocabulary, the texts and the exercises. Also, their teaching methods rely mainly on memorization of vocabulary, sentences and sometimes texts.

But they will always try to help you the best they can.

You very we'll may have teachers who can speak some english but know nothing about the subjects they are teaching, ie, an teacher from the english department teaching history  that passes time in class by asking the class if they went out and partied recently. Be careful of administration repeatedly changing rules on you if it is a new program ( english language programs often are) also if you have to do a thesis then make sure the school actually provides you with proper research resources (chuckle).

I went  to a top chinese university and that was my experience across the board. 

Chinese professors??? Hmmm. Wouldn't a 'real' professor be tenured in a university rather than teaching english to little emperors?

Do you mean unqualified teachers with a business card that says "Professor", holier than thou attitude and hardly any chops? Yep, that's them.

Sort of like the foreigner with a Foreign Expert Certificate that gets business printed with "Professor of English" or other such rubbish.

Well from my experience there are two types of Chinese professors teaching foreigners in unis:

1. Those who actually care, I had several of them, really knowledagble people decent classes, and they cared about the subject matter, very similar to what I experienced in the West. Although the requirements for papers and grading where severely lacking.

2. The face chasers, these professors don't give a shit about anything, they just want to gain face by teaching foreigners. I had exams about stuff we didn't cover in class, canceled classes and more. These guys were also knowledagble but they just didn't give a shit about us.
