Why doesn't Tongliao go to Beijing?

There are restrictions. Tongliao is not allowed to go to Beijing because of restrictions. The lifting time of Tongliao's restrictions on entering Beijing depends on the epidemic situation. Tongliao's restrictions on entering Beijing: those who enter Beijing must hold a negative nucleic acid test certificate within 48 hours and the green code of "Beijing Health Treasure"; After that, every time I went back to Beijing, I held a negative report of nucleic acid test within 14 days.
