Hello, I called the community, she said it will be very complicated if you return shanghai from japan recently. You tell me your confirmed flight two days in advance. It's better to arrive in Shanghai in the morning, because the airport will take four hours, and then the airport will arrange bus to take you to the compound. Doctors, WY people and police will wait for you and ensure you entry the room safely. You will be quarantined at home or other place, it depends on your health condition at that time and whether there are conditions for home quarantineing. The doctor will check the room two days in advance to confirm whether it is qualified. The most importantly, if you quarantine at home, you and your husband and your son cannot go out within 14 days. Please prepare daily necessities and food for 14 days in advance. Prepare a thermometer yourself, everyone will measure twice and record the number everyday and tell community.
