Someone asked how many kinds of diseases can be cured by external treatment such as lacing and slapping? Xiao Hongci, the author of "World Medical Skills", replied that most physical pains and medical diseases are related to obstruction of meridians and blood stasis. These external therapies can't definitely answer that they can cure some diseases, but they can help dredge the human body's 12 meridians, open channels of various acupoints, adjust the balance of yin and yang, restore the normal and smooth operation of qi and blood, and restore the profit and loss balance of essence and qi and blood. He also made an image metaphor, saying that the method of lacing and beating is equivalent to starting the anti-virus system in the human body, awakening the resistance nerve of the human body, and killing the virus in the diseased place or immediately eliminating it in the bud when the virus first appeared.
