You should go to Chengyang CDC to get a health certificate. It's in the north of Zhengyang Road People's Court. Take 1 inch photo, ID card, 50 yuan. But I have to go from Monday to Friday morning, so I don't smoke in the afternoon because I have to draw blood. It is best not to eat or drink water the day before.
And then it was done in a few days. Go get it.
