Does Linyi need to be isolated when returning to Laiyang?

It needs to be isolated, but it depends on whether you come back from the high-risk area in Linyi. Linyi isolation policy requires that outflow personnel from high-risk counties (cities, districts) be isolated for 7 days and monitored at home for 7 days, and those from counties (cities, districts) where middle-risk areas are located should be monitored at home for 7 days after arrival.
