Here are a few personal suggestions for the netizens: 1. Do not buy drugs from pharmacies if you are sick, it is better to go to the social health care. The doctors in the community are trained in formal general medicine and are more professional than the pharmacy attendants. 2. Have a medical checkup once a year. Because many serious diseases have no symptoms in the early stage, medical checkups can be detected and treated early. Life is fragile, I hope you cherish life, regular medical checkups, and regular treatment for illnesses.
