Since June 24, 2022, Xi 'an has been reduced to a low-risk area. Xi' an resumed normal travel, and those who left the city traveled with Xi' an's one yard "green code" without issuing a certificate of leaving the city. From now on, people who have returned to Yang in An don't need to issue a certificate of leaving the city, as long as they have a negative nucleic acid test certificate within 48 hours, and the travel code is "green code" and the Shaanxi health code is "green code", they can return to Yang. Before returning to Yang, you should take the initiative to report to your community or street.
