Excellent Tai Chi form Grandmaster Liang demonstrates the 24 form, with front and rear view, and also shows applications of each posture. This is the correct way to do the 24 form, which is commonly used in tournaments and demos. He also includes a bonus demonstration of the 48-form done by his student. The app also includes a slideshow of photos taken during Master Yang's performance so you can study each posture carefully and make slight adjustments to your postures.
