Today, I pushed hands with a friend for about 20 minutes. Nothing taiji happened for the most part, a bit of getting stuck, a bit of tuck-of-war, a bit of just moving around. However, for one move, my friend got bounced and both of his feet were off the floor together. According to his description, he felt he was lifted off the floor very lightly. I felt that the move was correct at the time, but I didn't really know how that was achieved either. It just happened. Hopefully, something similar will happen again in the near future.
