According to the announcement issued by the National Health and Wellness Committee, on June 8, 2023, the infection in novel coronavirus was changed from "Class A tube" to "Class B tube". By March 2023, health codes will no longer be needed everywhere, so there is no need to use health codes in daily life and cooperative medical care does not need to scan health codes.
Health code is a personal two-dimensional code based on actual real data, which is generated by citizens or people who have returned to work on their own online declaration and background audit.
