There are six basic requirements in doing good tai chi. The first three apply to the upper body. The last three apply to the lower body.
You can compare this to the Yang Style 10 important points by Yang Cheng-fu, referred often as one of the Tai Chi classics. You can see that these map to the classic 10 points, but in a more direct and organized way (but I am a little bias since I have these six points drilled into my head and body at this point).
I am always amazed how well these six requirements work. When one of my students have a problem with a particular movement, nine times out of ten it is because one of these requirements are violated. This is particularly true for the lower body requirements. Not following them results in wobbly stances, and awkward movements.
