Is it necessary to separate Putian from Xi 'an now?

No need. Putian, called Xinghua in ancient times, also known as Puyang and Puxian, is a prefecture-level city under the jurisdiction of Fujian Province, located in the middle of Fujian Province. According to relevant data, as of September 2, 2022, there were no new local cases in this area, which was in the normalization control area, so it was not necessary to be isolated from Xi 'an, and only the nucleic acid test was needed within seven days.
