I haven't posted videos in a while due to a new baby, so here is a basic breakdown of the taijiquan strike, and the 5 punches. From my experience, which may differ from yours, it's hidden hand punch, hook, overhead cannon, strike the earth and backfist. I may have missed one or 2 things in making this video, would love to hear feedback and comments.
