Do Chinese Have a Family History?

Raymond s asked, do some, or most, modern chinese have some sense of their family heritage in regard to the ancient stories of china? I know ancestor of veneration is important, but how much do they know or think about the history of their people witnessed, not just in the last one to 200 years, but many generations ago. Like everywhere, most people come from peasants or maybe slaves. So not a lot is known, most likely. But what do you think the average han chinese person in shanghai would have in their own families history, or know where their ancestors came from originally or descended from? Does anyone think or care about this?"
