First, I don't see the relevance of whether teachers in China value homework or not.
Second, YOU have to decide if you think that homework A) should be given in the first place and B) whether you want to look at it if you assign it and/or evaluate it and/or add something to the overall grading you do based on homework. Once you decide that, it makes your life a lot easier.
Third, just my opinion but ...I think the main benefit of homework is to the student. If you give homework, your job is to select problems/exercises/readings that help the student comprehend what they are learning ... better. Just assigning homework that is nothing but busy work seems rather pointless.
Now, given that ... if they want to do it or at least try to do it ... then potentially they will get some value out of that. Perhaps that is enough.
I would say however that if you assign homework, then you need to go over some of it (maybe not all) so that those who try but run into a snag or two, so that they can get back on track. If you don't go over it in class, then at least have some feedback mechanism where students can see what the correct answers are.
Finally ... there are many on this list who are adamant about both assigning homework and evaluating it in some way. There probably are an equal # who assign homework but do little with it ... other than perhaps go over selected exercises from time to time. Those don't evaluate it and don't grade it and it is not part of the grade in the course.
There are cogent arguments from both camps ... you just have to decide which camp you belong to.;-)
There is no right nor pedagogically correct thing to do about the issue of homework. I will say however that if you have decent sized classes, you can get overwhelmed with handling homework if you are not careful.
