Two people are demonstrating Tai Chi.  There is a garden with colorful flowers shown outside the Tai Chi school building.  The instructors wearing blue robes are showing the basic moves used in Tai Chi.  They are swaying their hands above their heads from left to right.  Then the instructor demonstrates arm strength by tapping his right arm over his extended left arm.  Both the instructors stand facing each other as they demonstrate slow and gradual hand movements.
