Because of the epidemic situation, visitors in and out of Beijing have to sweep health treasures. If they can't be swept out, they will not be allowed to enter, and their activities will be restricted, which is not illegal.
When entering and leaving Beijing, the "Health Treasure" itinerary verification can't get the green code normally. The reason for this situation is that Beijing is not filled in on the itinerary list in real time, or travel itinerary is not filled in completely, which is inconsistent with the travel itinerary card display. Solution: Fill in Beijing. If you forget or are not sure about the recent itinerary, you can click "Click Query" in the prompt at the bottom of the page, and keep the itinerary consistent with the query results when filling in.
