No need. Official website said that it is necessary to hold a nucleic acid test certificate within 48 hours, and all personnel should check the "three codes" (health code, travel code and nucleic acid report). If there is no nucleic acid test certificate within 48 hours, nucleic acid test must be carried out on the spot. If the health code and travel code are normal, you can pass freely. If the travel code is abnormal, such as in the middle and high risk area, and has a history of living in the streets of counties (cities, districts) or municipalities directly under the Central Government, after arriving in Qin, each checkpoint will push the personnel information to the destination headquarters, and the destination headquarters will carry out health management in strict accordance with the above requirements.
