There is a Japanese myth about Zu San Li who inherited significant information from his father:” long life spot” or “a hundred illness’ spot”.
He, following his father’s advice, massaged this spot every day and lived long enough to witness the birth and death of tens of empires.
In Chinese medicine, body is considered as an energy system and massage can affect the functional activities and energy flows of organs.
Zu San Li spot is under the patella. To spot this spot, lay your hand on your same side knee, fingers pointing down.
Your palm should be covering your knee.
For example, your right hand should be on your right knee. Zu San Li spot is between your pinkie finger and forefinger nails.
