According to the current epidemic prevention and control policy of the Office of the Leading Group for Epidemic Work in novel coronavirus, Guizhou Province, all people from other provinces (returning to Guizhou) must hold negative nucleic acid test certificates (both paper and electronic versions are acceptable) within 48 hours, and check their health codes and travel codes, both of which are "green codes", so they can pass freely if their body temperature is normal.
Pay attention to self-protection during the epidemic, wear a mask when traveling and wash your hands frequently.
