In foreign countries, great emphasis is placed on the body’s autoimmunity and the use of antibiotics is not advocated. Chinese people don't pay much attention to this aspect. On the one hand, they are ignorant, and on the other hand, they want to get better as soon as possible. They only care about immediate recovery, but they don't know that there are greater hidden dangers. The immunity to germs is also constantly increasing. If the dosage of medication is increased every time, the body's autoimmune function will decrease and it will rely heavily on drugs. Moreover, due to the weakness of one's own immunity, the risk of getting sick may also increase. This approach is very unscientific.
