Beijing Health Treasure Pop-up Window 3: Those who are already in Beijing must report to the community (village committee) where they live in Beijing or the community where their work unit is located, and the community will propose solutions (basically centralized isolation, self-isolation or going back to the local area). The self-made nucleic acid pop-up window cannot be lifted. Yanjiao people (commuters) have a pop-up window of Beijing Health Treasure (Beijing Science and Technology closed). Because Yanjiao released an epidemic report, there have been new infections every day recently, and Beijing stipulates that there are confirmed and infected cases.
