Will Shaoyang Huilong become a yellow code?

No. Will Huilong in Shaoyang City become a yellow code? Not all people who come back from other provinces will change the health code. If a red team or yellow code appears, there are three main reasons. First, cross-provincial or cross-regional activities. After leaving epidemic areas, high schools, low-risk and other key areas, big data will be generated and pushed to the next destination, which may be later than the flow of people. The second is the data source of health code, mainly the big data and epidemiological survey results pushed by relevant departments. These data will be pushed to the next destination after the outbreak or after the delineation of high, medium and low risk areas, so there is a delay in assigning codes. Third, no epidemic situation was found at the time of departure or no medium and high risk areas were delineated. After the epidemic was discovered, the possible start time of the epidemic was calculated forward through research and judgment, resulting in people who left the area in the past period of time being assigned as risk personnel.
