Yin-yang body sketch on the face

This Dien Chan sketch shows two ways on how to project the body on the face. The red man is the yang body and the blue woman is the yin body. We stimulate both with multireflexological tools to relieve structural pains.
For back pain for instance, using the most pleasant side, roll tool nº206 on your nose for 2 minutes.
Then, check for pain and continue rolling once more if relief has been felt.
