The differentiation of specific systems is based on their particular activity. They use external movement, or are done standing, sitting or lying down. These are described as Dynamic or Quiescent, sitting, standing or prone. The most common health maintenance systems use standing Quiescent - Dynamic postures. These can be seen in any park in China usually being practiced in the early morning.
People practice in groups or individually.
Often, they will stand in front of a tree or rock and they will try to absorb Qi from these natural sources of qi. The practitioner will assume a standing posture and hold a specific position for a period of time. While standing they may move their arms or body purposefully or they may hold their entire body still. Some systems use both dynamic and quiescent postures. Other systems encourage spontaneous movement of the body in accord with the flow of Qi.
