The message from the SMS said that Huang Ma appeared, but he never thought about how to reconsider.

Show me the itinerary code. The text says you have Huang Ma. You can check whether your health code turns yellow first. As long as you haven't been to high-risk areas, there will be no Huang Ma. You can reconsider in the local prevention and control risk area, show your travel code, and then ask the prevention and control area to re-test your health coding system.
