The three must-move's and three must-not-move's that must be observed in learning Taichi are: hands move feet must not move, feet move hands must not move, both hands and feet move at the same time. There are three must not move for the body that must be observed: Do not move too much, do not move first, do not move without thinking. The three must no do for the hands are: do not move, do not throw, last do not go against the flow. These must-move's and must-not-move's are very important in learning the skills. Taichi Quan pays attention to character building and the tranquility of mind and spirit.
