The Chinese people say much less "thank you" than the westerners, esp. between families and friends, or: the closer i feel with u, the shyer i feel to or even wont think of this formality of showing thx. but! it doesnt mean that we are not grateful! the way we show thanks is much more than just a thx, and sometimes even found overdone by people from other cultures.
Personally speaking, i d rather feel that people are thankful than hearing them ABUSE "thx" without any sincerity but just a formality. just like the fast food, easy and convenient.
I began to learn to say more thx since i lived more in mixed-cultural environment these years. but pls try to understand the "ungrateful" chinese people, most of them just didnt realize just a "thx" would be enough for u. and they also tried to understand u guys, since they are born friendly and harmless.
