The green code is a health code without any risk, red team needs to be quarantined for 14 days, the yellow code needs to be quarantined within 7 days after being in a medium-high risk area, and the orange code indicates that the health status verification failed.
In addition to the above, more and more people now call the four health codes: travel code, health code, travel code and vaccine code. Health codes and travel codes are the most common and commonly used. Formation code is also called formation card. Generally, you can know your personal health status by looking at the health code, and you can know whether to go to high-risk areas by looking at the travel card and judge whether there is any risk. Once you find something wrong, you will contact the medical staff.
