Health code is a necessary thing for everyone to go out now, because both children and adults can check the health code when they go out to take the subway or go to school, because the health code can know the real-time health situation of individuals.
First of all, China passengers need to fill in personal data, health status, recent travel situation and other information through the international version of WeChat applet before boarding the plane. Special circumstances can be filled in by others.
Secondly, in general, children need a health code to fly. If the baby is only a few months old, this situation is unnecessary. If children are over one year old, they can't fly without a health code, so parents can apply for a health code for their children before they fly.
After successfully applying for your own health code, you can add family members and add your child's health information to the management of family members. In short, health codes are very important for people to travel. Both children and adults need to use health codes, and children's health codes are usually made by parents, which makes it more convenient for parents and children to go out. Now, both trains and planes need health codes.
