Do I need to be quarantined when I go back to Yiwu today?

No need. Yiwu is a county-level city under the jurisdiction of Zhejiang Province, managed by Jinhua City, which was called "Wu Shang" in ancient times. Jinhua-Yiwu (central Zhejiang) ranks as the four major regional central cities in Zhejiang along with Hangzhou (northern Zhejiang), Ningbo (eastern Zhejiang) and Wenzhou (southern Zhejiang). According to the introduction of the epidemic prevention and control center in this area, the epidemic situation in Yiwu has been cleared and it belongs to a low-risk area. No quarantine is required before September 22, 2022. People entering and leaving Yiwu need to wear masks and show their health codes and travel itinerary.
