In general, the five zang organs and six fu organs, as well as the Ying (Nutrient) Qi, Wei (Defensive) Qi, and all orifices of the body, should maintain a state of harmonious and smooth blood and qi circulation, endless and continuous.

The key lies in, when facing illness, to keep the spirit inwardly focused, practice internal observation, regulate the breath inwardly, avoid random visual distractions, and concentrate with meticulous attention.
