Use of health codes
Health code was born under the background that the whole industry chain is trying to resume work and production. It is a new technology to establish an economic and social operation order suitable for epidemic prevention and control. During the epidemic period, the health code is the product of strengthening the joint prevention and control of COVID-19 epidemic by using big data.
Simply put, it is a proof of a person's health, because the epidemic is still very serious. Only by proving your health in this way can you go to other places and ensure the safety of people in other places. This is very necessary, so we must actively cooperate.
