Wutan’s version of Cheng’s form as adapted and considerably shortened from the Yang Long Form.
My own notes are here and are more detailed and potentially more confusing. This presentation might suit a more confident and/or experienced student.

Dr Cheng explains that like most Chinese Martial arts, Tai Chi includes the ability to:
Kick
Punch / strike
Throw, and
Joint lock
