First, cold medicine and antipyretic medicine. This is absolutely necessary, because you usually have a cold and fever at night and feel uncomfortable after getting up. And maybe your school is a little far from hospitals and clinics, so you can take medicine first. If your cold is not serious, there is generally no problem and you don't need to see a doctor.

Second, band-AIDS and medicines for traumatic injuries, such as safflower oil, are good. Injuries at school are inevitable, especially in physical education class. If there is a wound, use a band-aid to prevent bacteria from entering the wound. No matter the size of your wound, you'd better use a band-aid.

Third, herbal tea granules. Eating too much and eating too little in the school cafeteria will get angry. And sometimes you can't help eating things that get angry, so you should prepare herbal tea granules, so you don't have to go to the herbal tea shop outside to buy them.

Third, the medicine for stomachache. I recommend Baoji Pill and Huoxiang Zhengqi Liquid, which are especially useful. You'll always have a stomachache. Get this ready first, or I'm afraid you'll pass it.
