Yes, we just featured Michelle’s ping pong game as Saturday’s Photo of the Day, but the repetition is worth it. During a visit to a Chengdu high school, the American first lady joined a tai chi group in a nearby park and, judging by these photos, didn’t exactly know what was going on but made a valiant effort. Hopefully Mrs. Obama’s China tour will also include joining a group or two of elderly dancing women in city parks.
