Can the epidemic situation pass Tongling now? What code does the mobile phone change?

Of course. Code yellow or red team.

If the green code holder enters the low-risk area without special circumstances, the health code will not change color, that is, the normal green health code. If the holder of the green health code enters the middle-high risk area and stays for 1 hour, and the mobile phone can normally receive communication roaming information, the health code will automatically change color from the original green code to a yellow code or a red code.
