Do I need to issue a nucleic acid test to fly to Yinchuan from Shanghai recently?

No, they are all low-risk areas, no nucleic acid testing is required, the green code is a must

Those who fly back to Shanghai must follow the community epidemic prevention regulations, and it is estimated that nucleic acid testing will be required

It is best to have a nucleic acid test report, because Shanghai Pudong New Area is still the focus of control, which is responsible for oneself and others.
