Before the introduction of the Health Code, many cities were closed or people were afraid to go out easily because of extreme fear, and the normal communication between people and the social and economic order were seriously damaged. People have doubts in their hearts, so they dare not contact with others too much. After the birth of health code, the order of people appearing in large entertainment places increased obviously, and many epidemic prevention personnel also made it convenient to inquire about the physical condition of citizens. Even at present, we can see staff holding code scanning equipment at the entrance of hospitals or some supermarkets to confirm the physical condition of citizens.
Scanning code can prove health for yourself. For others, it is the guarantee of life safety. It shows that a person is serious and responsible for epidemic prevention. Nowadays, health code is one of the indispensable tools for people to travel, and it may be tested at any time, so its importance can be seen.
With the progress of epidemic prevention, many provinces have reformed the health coding technology. Now people who have been vaccinated with COVID-19 vaccine can get their own unique golden health code, which shows that the health code is constantly upgrading, and it can be regarded as satisfying people's psychology of unlocking new achievements.
