Is it necessary to isolate Xiayi from Wenling?

No need. As of September 28th, 2022, according to the inquiry of Xiayi epidemic prevention department, Xiayi belongs to the normal control area, so it is unnecessary to go to Wenling, a county-level city under the jurisdiction of Taizhou City, Zhejiang Province, where the first sunshine shines in the new millennium and the new century in Chinese mainland.
