The health certificate is handled in the urban CDC, and you should bring your personal ID card and cash.
2. Before handling, you can check the relevant procedures and requirements in official website, CDC.
3. You don't need to take photos to get a health certificate. You can take electronic photos for business card printing. The photo fee is included in the processing fee, and there is no extra charge. Take Yuelu District of Changsha as an example, 45 yuan can do it.
The staff starts work at 9 o'clock, so I personally suggest that you don't have to go too early. The queue is very tired, and there will be few people around 10: 30. If there is no queue, the whole process can be completed in about ten minutes.
