Asking parents to upload health double codes and travel codes not only protects themselves, but also protects people around them. Its function is not only to report personal health, but also to master your action track. The use of "health code" travel code in epidemic situation has become a passport for children to travel, and each child has his own health code.

Green health code means that you are healthy, but this is only one of its basic functions. The function of health code is not to prove that you are healthy, otherwise you are not allowed to declare your physical condition and then report it. It is actually similar to the QR code of an electronic identity.
Because it is still the epidemic period in COVID-19, applying for a travel code can ensure your own safety, and colleagues can also ensure the safety of others. Only when the travel code is green can it be healthy and safe.
