I haven't received any text messages about nucleic acid anywhere.

The sooner the nucleic acid, the better.

According to the epidemic prevention and control requirements of normalized nucleic acid detection, if you receive a short message without nucleic acid detection since May 16, 2022, please detect the nucleic acid as soon as possible, and automatically decode it after the result is negative. If you have any questions, you can call the distribution codes of counties (cities, districts) in Taiyuan City in time to appeal.

Can people who have returned (arrived) to Shanxi Province complain through "code health" after receiving the short message from Shanxi Province?

The Shanxi Provincial Health and Health Commission has opened the "Shanxi Health Code" Internet complaint channel. You can search for "code health" through Alipay APP to enter the applet, select the corresponding health code color to enter the complaint page, and submit the required information according to the prompt to make a health code complaint. The appeal results can be inquired in the small program, and each person can submit an appeal application once a day.
