Health codes have greatly improved the efficiency of information verification in epidemic prevention and control, but the combination of codes has created a new problem, that is, only local codes are recognized locally. Those who hold the "green code" in low-risk areas need to reapply for the "code" of the destination when they return to work by relatively independent and closed means of transportation, which consumes a lot of time and energy, brings endless troubles to the masses and enterprises, wastes social resources, and is not conducive to establishing an economic and social operation order suitable for epidemic prevention and control.
Recently, the national epidemic situation has improved, and many provinces can pass it, which requires us to provide the health code. General health code green is no problem.
