When I visited Beijing I mistakenly referred to the exercise grounds in a park as kid's playgrounds... turns out they're actually there for seniors to use and they sure do... crowded every day. Sidewalk food vendors along every street also promote socializing. Chinese friends of mine would like to bring their parents from China, but they're having nothing to do with it. They don't want to lose the active social network they have at home.
