I think a lot of people are skipping over the fact that Asian parents still rely upon their children, especially males, after they retire. It's not uncommon to see Asian parents, their children and their spouses living under one roof. More likely than not, it'll be the Asian parents + their child + his spouse under one roof with the other children supporting them financially.
Just as a quick note on the creativity/innovation in Chinese history, I really think the cuisine should fit into this. Although technology advancements is the base criteria for such things, the huge variety of cuisine and the different techniques used plays a small but significant role. In my 'culture' of Fuzhou, soups are a quintessential accompany to the meal. Every week, I would have like 4 different types of soup, some containing a 3-5 ingredients and others involving 10-20+ ingredients that harmonize together. Some sweet. Some bitter like hell. Some oddly sour. And some savory or Umami I think was the term. My mum knows dozens of them. And that's only soups.
Sure you can claim that such recipes are passed down generation by generation, but you cannot deny its origins. Why anyone would place tree bark, roots of other trees and flowers, berries, some fermented vegetables etc. together in a soup deliberately without going "Oh hey, let's try something new today" is beyond me.
