In today's society, health code is closely related to people's lives. If your health code turns yellow or red, people in some places will refuse to enter. You can tell your current situation from the health code, for example, you have not done nucleic acid testing, you are a close contact, or you are infected with COVID-19 virus. At first, the health code of each place is different, so you must apply, otherwise you may be blocked when you go to a certain place. However, mutual recognition of health regulations has now deepened. For example, some netizens claim that they are from Hebei province, and when they go to other provinces, such as Tibet and Zhejiang, they can display relevant information in the health code of Hebei province.
If there is no national mutual recognition in the province, it may be that the local health code system has not been upgraded or the data has not been updated in time. Some netizens said that the health code may always exist and will not disappear in our lives, so mutual recognition is imperative, otherwise it will be too much trouble. Now, you should not only look at the health code, but also have a travel card. If you stay somewhere, the mobile phone operator will locate it. You can also show travel itinerary to prove that you have not passed through the middle and high risk area.
In fact, it is not so important that health codes do not recognize each other, because it is not so difficult to apply for a health code, but if the nucleic acid test results do not recognize each other, it may cause a waste of resources.
