Due to the large number of confirmed cases in Guangzhou, it is clear in Guangzhou that those who leave Guangzhou must show negative proof of nucleic acid test within 72 hours with the green code of "health code". It can be seen that people who come back from Guangzhou now don't need isolation, but some places require conscious isolation at home and do a nucleic acid test every three days.
However, people from other low-risk areas in China need to hold a green code when coming to Guangzhou, and their body temperature is normal, so there is no need for isolation. However, when people from high-risk areas come to Guangzhou, they must have a valid negative result of COVID-19 nucleic acid test within 7 days, and they need to be quarantined for 14 days. Everyone must see clearly.
