The patterns in the middle of the health codes in different provinces are different. The following is a detailed introduction to the provinces:
1. In the middle of Fujian Health Code is the provincial flower "Narcissus", which symbolizes all beauty, good luck and beauty. After vaccination with COVID-19 vaccine, the middle pattern of "Fujian Bamin Health Code" will be changed from the original Fujian symbol to two banyan leaves wrapped in a daffodil.
2. Zhejiang has completed all doses of vaccination. The symbol "snake stick" will be displayed in the middle of the QR code, and "COVID-19 vaccination completed" will be displayed below the QR code, and it will be displayed in green font.
3. Only after I was vaccinated with COVID-19 vaccine, the health code of Hebei Province will turn golden. If a small crown appears on the health code, it means that I have been vaccinated with COVID-19 vaccine (twice or three times).
