You don&;t need to isolate Wuhan from Guangzhou now, because Wuhan is no longer a high-risk area. You only need to prepare the nucleic acid test report and the trip code nucleic acid test report in advance, and you can leave for Guangzhou within 72 hours at best. Generally, there will be no problems. If it is too troublesome, you can do the nucleic acid test after you arrive in Guangzhou. The cost is almost the same, and maybe it is cheaper.
