Is it necessary to isolate the expressway from Jiangsu to Qixian?

No need. Qixian County, which belongs to Jinzhong City, Shanxi Province, is located in the middle of Shanxi Province. According to the inquiry, the epidemic prevention and control department of Jiangsu Province shows that Jiangsu Province is a low-risk area as of September 27, and Qixian County only needs to show 48 hours of nucleic acid testing to see a doctor in the low-risk area, so it is necessary to isolate the expressway from Jiangsu to Qixian County. Jiangsu, referred to as "Su" for short, is the provincial administrative region of People's Republic of China (PRC).
