What does the health code mean with an asterisk?
The asterisk only indicates that you have been to a city in a medium-high risk area, but it does not mean that you have been to a medium-high risk area.
There are cities with asterisks in travel itinerary, and your health code is green. This situation will basically not affect your travel, but you still advocate reducing unnecessary walking and not going to middle and high-risk areas unless necessary.
Generally speaking, as long as your health code is green, it will not affect your travel, but if it becomes yellow code and red code, you should consciously carry out centralized isolation and home isolation.
