Yin Qi and Yang Qi
Most Chinese medicine practitioners think that there are many kinds of qi 气 (qì), and the most basic kinds are yin qi 阴气 and yang qi 阳气.
Everything is a balance of yin and yang. Yin 阴 is female, dark and formless. Yang 阳 is male, light, and form. Females have more yin qi, and males have more yang qi, and as people age, they lose qi.
Achieving a Yin-Yang Balance
It is theorized that each person and part of the body has an ideal point of balance of yin and yang for optimal health. Some techniques are more appropriate for increasing yang qi, and some are appropriate for decreasing yang qi, and likewise for yin qi.
