Will Health Treasure always locate after scanning?

The health code opened after closing will still show some places I have been during that time. Because the health code locates the location according to the location of the mobile phone. Unless the location of the mobile phone is turned off, it is useless to turn off the health password, or leave it at home and don't take it anywhere else, so there is no way to monitor the location. After the health code goes online, through the dynamic management of green, yellow and red, the state of each citizen during the epidemic prevention and control can be determined. You can use plain code to enter communities, offices, restaurants and other occasions to facilitate the work, life and travel needs of the general public. The health code system is updated in real time according to the comprehensive situation of the public. If people stay in areas of concern or come into contact with high-risk groups, the health code will turn red.
