Do I need nucleic acid when returning to Shifang from Dujiangyan?

Yes.

Dujiangyan’s policy for entering Shifang: Persons coming (returning) to Sichuan with a history of traveling to counties (cities, districts, banners) where local epidemics have occurred in the past 7 days should register with the destination community (village) in advance . For those who have a history of staying in low-risk areas for 7 days, they must complete 3 nucleic acid tests within 3 days and conduct health monitoring. Other areas in the county (city, district, banner) where the medium- and high-risk areas are located are low-risk areas.
