Yu Kangma popped up but didn't send a text message.

Yukangma didn't send a text message, and the pop-up window disappeared after 28 days. Personnel coming to and returning from Chongqing shall conduct 1 nucleic acid detection and sampling at or near the traffic port. After receiving the nucleic acid sampling information, Yukang Code recovers the green code. If there is no nucleic acid detection and sampling, Yukang code will remain in the pop-up state until the nucleic acid sampling is completed. At the same time, for those who have not taken nucleic acid detection and sampling for more than 24 hours, Yukang Code System will automatically send information prompting nucleic acid detection and sampling. If a pop-up window is received, it needs to be tested twice as soon as possible from the time it becomes a pop-up window (the interval between the two tests must be 24 hours), and the result is negative, and the control measures have not been upgraded after the community investigation, then the pop-up window is eliminated. If the nucleic acid test is not carried out as required, the pop-up window will be eliminated after 28 days.
