Moreover, in 20 19, many people's travel was greatly restricted because of their serious illness, especially in areas with serious epidemic situation, it was very difficult to go out to buy food, and some elderly people were illiterate and could not use QR codes. This situation also exists, and it is more common in hospitals, but all channels without health codes can be used except hospitals. Health code channel can also be used in other places, such as large supermarkets, because sometimes the elderly will go to supermarkets to buy things, so supermarkets are also suitable for health code free channels.
Moreover, after the internal epidemic situation in China slowed down, many people stayed at home during the epidemic, so many people would choose to travel and relax after going out, and so did some elderly people. However, some elderly people have problems with the use of smart phones and health codes, so channels without health codes can also be used in some places where health codes are needed.
The purpose of using the channel without health code is to facilitate the group's travel, and in this process, it also brings a lot of convenience to people's travel, which does not hinder the people who travel behind, and also saves their travel time, so the channel without health code plays a great role in saving time, so there are many places suitable for the channel without health code in daily life, such as supermarkets or some places that need health code for travel.
