Problems in handling health certificates in Beijing

You can go to the epidemic prevention station in Dongcheng District. I went to the district epidemic prevention station to get a health certificate, and I did it the next day. I asked the doctor, and the doctor said that I could come out so soon, and I must have checked nothing. Just to make money. You can try it there. As long as your chest X-ray is ok, it's almost the same. And be on an empty stomach, because there is something wrong with the liver, so you must not eat greasy food the day before ~
