Isn't the Seven Stars based on Yang?
Personally I found a difference between my TKD forms and TC forms in that I am continually moving while learning the TC. This is where it is useful. MY TKD forms were taught quite stiffly.
Now, many of the moves will have several applications which don't always become obvious until you are shown. For example, a whip coul;d turn into a block, a strike, or a trapping move.
A step could be a kick of a sweep or an avoidance of a sweep.
Enjoy your training.
See how well I block your punches with my jaw!!
