It seems to me that old(er) Chinese people, I am assuming retired, are pretty good at having a good time. You see them out and about all the time, especially in the parks, where they play ping pong, mahjong, cards, or going for a walk or simply hanging out. To me that seems like a nice thing to do, they are being social meeting people, they get out and get some fresh air (relatively speaking, we are after all in China), they quite simply find activities to fill their days with. Good for them! I want to sit outside in the park playing mahjong all day when I get old(er) too.
