Chinese people and jobs aren't a uniform thing, just like jobs in any country. Even within the same organization, different departments can have wildly different cultures. Check out what the typical US Physics professor wears vs the typical Geology professor if you want to see an example. What might be seen as a foreign employee doing a good job fitting into one place might be viewed as excessive or not enough somewhere else.
Also consider - how would a Chinese FT in your country address the same questions? That person will also encounter cultural oddities and unexpected terms and conditions for dealing both with job responsibilities and just fitting in. In either direction, some people can find a way to fit in and some people find the situation isn't worth it. The exact same thing happens when looking for a new job in your home country. Sometimes, you and the culture of the employer will fit well. If not, sometimes the fit is so bad that the choice is to suffer great unhappiness or else leave.
Hopefully, the place you work for values you for more than your pretty face and more or less standard spoken English, but the same could be said about teaching jobs in Australia or the US. Some really do want diverse opinions and some want absolute conformity. Happily, most places that go to the effort to hire foreigners realize that absolute conformity isn't a likely prospect.
I think the key is to have a general level of respect for the local culture. You don't have to jump in a dragon boat the way I do, but if your colleagues are out there paddling with all their might on race day, showing up is the polite thing do do even if you aren't a dragon boat fanatic the way I am. When I hear 5 or 6 houses near me setting off fireworks at 4 am, I'm not happy to be awakened, but I also know it's some sort of local holiday thing, so I don't run around demanding they stop. If people did that in a subdivision in the US, a very common reaction would be to call the local police and make a noise complaint. In China, I just mutter something about "Happy fireworks day" and go back to sleep.
An important thing to remember is that some local customs (even those confined to a corporation or educational institution) will look silly to you, but if we brought foreigners into communities and jobs in your hometown, some local customs would look just as silly to them. One thing I absolutely love about being here is when someone asks "Why" I (or Americans or Westerners) do something. Things that "are this way because things have always been this way" back on the homeworld often turn out to either be silly or unimportant when examined carefully.
Be open minded, be respectful, and try to approach things with a sense of humor is my best advice, whether you are doing something as big as getting a job in a different country or as small as moving to a new department at a job in your hometown. If it turns out to be intolerable, then leave as soon as possible. If it's just bad, keep an eye out for new opportunities. If it's good, stay and enjoy the ride.
