/kloc-0 returned to Qiyang from Guangzhou South Railway Station for nucleic acid detection on June 4th, April. Do I still need to do nucleic acid testing when I return to Guangzhou on June 9?

On June 4th, Kloc-0/9, I returned to Quyang from Guangzhou South Railway Station for nucleic acid detection. Do I still need to do nucleic acid testing when I return to Guangzhou on June 9? Although you set out from Guangzhou on June 14 and did a nucleic acid test, you will also do a nucleic acid test when you return on June 19. As long as you leave and come back, you need to do nucleic acid testing.
