The national government service platform is said to be a secret link, and the Yunnan health code is not a secret link. What happened?

On the basis of health code, the introduction of health code aims to make the return to work more accurate, scientific and orderly. The secret code is a kind of two-dimensional code, which is equivalent to the self-examination service for people in close contact with peers launched by the national government service platform and the National Health and Wellness Committee. It is convenient for the public to inquire whether they are in close contact with patients safely and quickly. As long as you scan the code and fill in your personal information, you will know if you are a close contact. The health code is based on the actual real data, which can be generated by citizens or people who have returned to work on their own online declaration and background audit.
