GW Hater you are absolutely right. Apparently chinese bosses think they own you just because you have signed a contract with them. This entitlement mentality is completely unfounded and goes against the very basics of decent human nature and how you should conduct business properly. If you point out the mistake immediately the employer will give you the look of a landowner from feudal times who looks at his/her peasant. There is no proper rationale, no reciprocal partnership. It's all about the control and the maintaining of everlasting shallowness within the mind for this sorrowful culture.

As for those brats who can't get good grades due to them being spoiled rotten, they are the first ones to backstab and tattle on a teacher and make up all sorts of stories. I would gather these folks will go about their whole lives tattling and blaming others for their own mistakes. I certainly learned from mine: Never ever be genuine about your own feelings with these mainlanders, the degrading mindset which as been brewed into the population is never something to take lightly. You will learn the hard way why human beings can be more vicious than animals, and you will be thankful there are societies which aren't so barbaric.

I stated in East Asia (which includes the Phillipines, China, Japan, and the Koreas) people have a hard time admitting they are wrong, especially when they receive criticism.

My experiences in China certainly mirror what you've said re the mainlanders. Passing the blame when things go wrong is evident among all age groups of mainlanders. This is the easy way out for a people who are very nationalistic, yet though spouting the concept of teamwork as a great doctrine, don't practise it individually. They always place their own interests first and ahead of those of the group. I've every reason to believe this also applies to East Asians in general.
Mainland foreign teachers should be aware that when it comes to teaching contracts, the employer takes the liberty of assuming he has the right to break them, whereas he will come down hard on any FT who dares to do so. One rule for them, and a diametrically opposite one for us. If you call him to account re his breaking his side of the contract, thus making him lose face, you'll win a battle, but you'll lose the war. End of contract, not a hope in hell of a renewal - you'll never be forgiven, and you'll be branded a troublemaker, even though you were careful to point out the breach in a polite way.
These days, Chinese students are too quick to blame their teachers for their poor examination grades, especially the offspring of the wealthy. After all, daddy will believe their lame excuses and switch them to another shonky private school.
