Thanks for your reply, I still have a couple of questions here.
First, I do not quite understand why Chinese espacially mid-class consumers are willing to pay high price if not highest price for a so-so product?
Second, I do not want to see that my sister wastes time and money if Amway(MLM) crashed at some point? So the question is how long it will/can go. And I check the history of Amway on the internet, so far, I do not see it happens in any country yet.
