According to the information on the Internet, self-help travel abroad has the following correlations:
"International Vaccination Certificate and International Travel Health Certificate In addition to your passport and visa, you should also apply to the local quarantine department for a health certificate and receive relevant vaccination.
All cities have special local health and quarantine bureaus. You'd better apply for a physical examination at the quarantine bureau two weeks before going abroad. Under normal circumstances, two two-inch busts should be submitted when applying, and the "Application Form" should be filled out, indicating whether the validity period is half a year or one year, and the fee should be paid. After completing the formalities, you can receive a health check and apply for vaccination at the same time.
There are two main kinds of vaccination: cholera and yellow fever. The validity period of cholera vaccine is 6 months, and the validity period of yellow fever vaccine is 10 year.
After the health examination and vaccination are completed, the quarantine bureau will inform you to collect evidence in one week or 10 day. If you want to get a license quickly, you have to pay an "expedited fee".
The above two documents are universal in the world, especially the vaccination certificate, which is called "Huang Ka". This is an effective document when traveling internationally. When you go abroad, the security department will ask you to provide these two certificates. If you forget this procedure in China, the airport security department will arrange for you to have a check-up and issue you a new card. "
PS: I remember that when I first left the country, when I applied for a visa, I was required to go to a hospital designated by the destination country in China for a comprehensive physical examination, otherwise I would not be granted a visa at all. It is a kind of distrust, but in fact, those designated hospitals may have better hardware facilities. Other tests besides blood test and urine test are really a trick, and the data itself may not be very important. If you want to go abroad, don't expect anything in the end. Unlike many other countries and even Southeast Asian countries, we have no visa-free and landing visa treatment (with a bad reputation). If you really want to go abroad, whether it is traveling, visiting relatives, studying or working, it is a big deal. Don't take it as a joke. Of course, if you are not going to the destination country for the first time, you don't have to go through these procedures unless you are in a special period such as SARS.
