Will Time and Space Companion turn into a yellow code when the phone is turned off?

Time and Space Companion will not turn yellow code when the phone is turned off.

As long as you go to a high-risk area and stay there for more than 4 hours, the itinerary code will turn yellow or red. If everyone takes the same subway, it won't turn into a yellow code. After all, you haven't come into contact with anyone in this field.

Notes on yellow code:

Don’t be too anxious. You may just have some exposure risks. At this time, you only need to report to the community and go to the nearest nucleic acid test on your own. The agency conducts testing, but you need to be careful not to take public transportation during the journey. We will generally perform two nucleic acid tests on you within three days, with an interval of 24 hours based on the sampling time (i.e., "two tests in three days"). After the nucleic acid result is negative, your health will be confirmed by the relevant departments. The code will automatically be converted into a green code.
