Results : Japanese colonial policy regards the colony people's old adage of health as outrageous things. Japanese colonial police demands don't use old adage of health because it is obstruction to colonial hygiene policy.

In addition, the knowledge derived from traditional Korean medicine was turned away outrageous things. Traditional Korean medicine knowledge lost the chance of renewal.
