Lalegue, that seems a bit of a leap to say "what does it say about a culture/race of people" with regard to how they treat animals.
Firstly, China is a big place (obvs). People there hold a wide variety of opinions on a wide variety of things. I've had quite a few Chinese students as a teacher and as a host family, and some of them have been vegetarian (they try to match veggie w veggie host where possible). So it's not like it's all animal abuse across the large landscape/population 24/7.
Secondly, as a vegetarian I find it appalling that people eat animals at all. I remind myself it's a cultural norm, but it hasn't been my norm for over 30 years and the longer I'm not eating meat the more agog I am at the practice. In North America it seems like there's constant reports of abusive practices in slaughterhouses and dairies. Most of those places are not abusive (beyond the meat is murder thing), but enough are.
Thirdly, it's been said before and people mostly have highlighted the treatment rather than the species, but for those of you who are bothered about eating cats and dogs - this is an artificial distinction in our culture. Pigs are smarter than dogs, for example, and make very loving pets. Cows have strong, loving family ties and all mammals feel pain and fear. This is one of the reasons I stopped eating meat - I thought "well, I wouldn't eat my cat ... ohhhhhh".
I think, to me, it's a matter of degrees of not seeing animals as having rights.
