Where is qi

When Yin rises, Yang depletes. Then Yang rises, and Yin starts to deplete to reach a new balance.

All your health problems, physical and mental, are the symptoms of a distorted system programmed by you and your environment unconsciously.

If you have abundant qi inside and can connect with qi outside, your health and well-being will never be a problem.

When the sun rises and sets, the energy transitions dramatically. Therefore all lives will respond to that transition, humans included.
