From the point of view of Chinese medicine, the wind and cold are still on the surface of the muscles, still in the body, and the evil may enter the lungs, resulting in the lung Qi is not declared, so when the Wei Qi is not enough, this external evil attack again, may be a cold. Secondly, the body is weaker and the immune system is weakened, so when there is a change in the weather or a change in the heat or cold outside, there will be a cold, which is just a manifestation of a decrease in immune system and a deficiency of qi and blood. For the first kind of situation, it may have to be directly cured by a series of adjustments.
