In order to reduce the crowd gathering, Yanji CDC has launched an online appointment service for health certificates from now on. Relevant employees need to make an online appointment by scanning the QR code. After the appointment is successful, you can apply for a health certificate on the first floor of the CDC according to the appointment time. If you don't apply for a health certificate within the specified time, you need to make a new appointment. When you come to apply for a health certificate, you need to bring your ID card and a negative nucleic acid test certificate within 48 hours. At the same time, do personal protection, wear a mask and keep a safe distance.
