As the saying goes: "Hair should be combed frequently, face should be rubbed frequently, eyes should be transported frequently, ears should be beaten frequently, tongue should be licked, teeth should be knocked frequently, body fluid should be counted, turbidity should be kept, back should be warm, chest should be protected, abdomen should be rubbed frequently, valley channels should be pinched, limbs should be shaken, skin should be dry, stool should be forbidden, and soles of feet should be rubbed frequently." This is the common sense of ancient people's health preservation.

Always rub the helix or pull the auricle, and be careful not to live in a noisy environment or dig your ears frequently, so as to achieve the purpose of health care.
