Should Chengdu be isolated from Wanzhou now?

No need. Chengdu is a prefecture-level city under the jurisdiction of Sichuan Province, referred to as Rongcheng and Jincheng for short. It is the capital and sub-provincial city of Sichuan Province. As of September 26, 2022, Chengdu only needs to take the initiative to report and hold a 48-hour nucleic acid report to Wanzhou, which is a very good city without isolation.
