Where can Longhua apply for an entry-exit health certificate? how much is it?

You can apply for a health certificate at the local international travel health care center (I don't know if you are Longhua in Guangdong, Longhua in Jiangxi or Longhua in Jiangsu). If you are from Longhua, Jiangsu Province, you can also go to the Municipal Center for Disease Control and Prevention to apply for the general health certificate of Longhua, but you need 480 yuan to apply for the entry-exit health certificate.
