Though I learned this sequence the first year that I started Tai Chi, learning it movement by movement, we are still practicing certain moves. Cloud Hands is one that we do regularly as well as the two moves where one does the leg raises. We practice the leg raises every session, doing 8 on each leg, and holding the position for at least 30 seconds if not a minute. I am finding this quite the challenge to both my balance and my endurance. It requires a lot of strength to hold your leg up that long, and is something that I need to practice every day if I am to get it right. One of the stories our Master tells us is how the Master of her school practiced only these 8 steps during the Cultural Revolution, because that was all he knew. But he got to know them so well, that he was able to make incredible progress once it was once again licit to teach tai chi.
