It is not really about communists roots or anything. Old Chinese people believe in herbs, and believe anything unnatural is bad for your body. Especially old people, they believe doing less to your body is best for you, just let the nature take care of it. As for your grandparents, I don't think anything should be trusted blindly. It is very personal thing. For an Asian to take something 1/10000 of death/or other rate, it is not worth it. That's why many Asian still wear masks. The best way to understand developing world is to compress 4 generations or even more into two generations, like comparing the thoughts of your great great granddad to yourself, that's how fast developing world has developed, and the gap between generations can be so big.
