Agreed, in asia a family unit is not just parents and their children. It involves, grandparents, and great grandparents if they are around. It's not a "you have to take care of me" kind of a deal but something like "family takes care of itself" -> when you have kids, grandparents help out actively in raising them, then you are adults you help your parents, physicall, financially. Families often have assets stowed away as a collective unit.
