Why is Hebei health code displayed in Shandong for 7 days?

According to relevant information, Hebei health code was displayed in Shandong for 7 days because Shandong upgraded the health code. In June 2022, Shandong upgraded its health code. When people scan the code to display the health code, they will also display the 7-day nucleic acid detection mark. If there is no negative record of nucleic acid test within 7 days, the sign will turn yellow, that is, a yellow card will be displayed. Citizens who are "shown yellow cards" will be restricted from entering and leaving public places. It is hoped that the general public will consciously abide by the epidemic prevention regulations, take the initiative to participate in nucleic acid testing, and build a defense line for epidemic prevention and control. Therefore, there will be a phenomenon that Hebei health code is displayed in Shandong for 7 days.
