First of all, since the outbreak of 19 in February, the epidemic has finally been controlled through the continuous efforts of our military medical staff and national security personnel. After the epidemic situation is controlled, the suspicious persons will be controlled at the source through different protection methods. Therefore, China has promulgated the Health Law and the Travel Law. It is worth mentioning here that the health code will not read the user's geographical location, but only show the basic information of the code holder and the basic situation of whether he has been vaccinated.
Secondly, it is the travel code that needs to read the user's geographical location.

You don't need to fill in the information to find out that you stayed in China for 4 hours in the first 14 days and have been to cities in other countries. Your itinerary is based on your cell phone signal. Where is your cell phone signal, your itinerary will be displayed.
