If you are a passenger in a low-risk area, you generally don't need to do nucleic acid when you take the high-speed train, and you don't need to show a nucleic acid test report when you enter high-speed railway station. You just need to show your health code, green code, travel code and temperature measurement.
According to the national epidemic prevention and control requirements, it is necessary to have a negative nucleic acid test certificate within 48 hours when going out by means of transportation, and the health code and travel code are green codes, so that the body temperature test is normal.
