27日起上海对入境者实施有条件的“7天集中+7天居家”隔离措施 - 2020年07月23日

Starting from July 27, people who arrive in Shanghai from overseas can spend half of their quarantine time at home if certain conditions are met, authorities announced on Thursday.
For now, though, all such people will remain subject to a compulsory 14-day quarantine at places designated by the government.
For those whose destination is Shanghai, under condition that they have residency in the city, live apart from family members who don't have to be quarantined or live with people who agree to be quarantined along with them, they will be sent home to resume their quarantine on the eighth day if their nucleic tests on the fifth day are negative and if they apply to be quarantined at home.
