Do I need to quarantine when traveling to Ankang from Sanmenxia Mianchi County?

No need. Mianchi County is affiliated to Sanmenxia City, Henan Province and is located in the northwest of Henan Province. Ankang City is located in the southeast of Shaanxi Province, bordering the Qinling Mountains to the north, Bashan Mountain to the south, and the Han River running from east to west. Check the epidemic prevention and control information in the two places as of today, September 14th. Traveling from other places to Ankang does not require quarantine. You must wear a mask and hold a 48-hour nucleic acid certificate.
