Is it necessary to isolate Chengmai when Haikou comes back from seeing a doctor?

Need. Haikou, also known as "Coconut City", is the capital of Hainan Province and the fulcrum city of the national "Belt and Road Initiative". Chengmai County is located in the northwest of Hainan Island. As of September 7, 2022, according to the requirements of disease control and epidemic prevention in Chengmai, Hainan, any person going abroad (territory) should strictly carry out "three days and two inspections" on the basis of conducting nucleic acid testing within 24 hours, and strictly implement home (hotel) isolation before the results of nucleic acid testing come out. The nucleic acid test results are all negative and can flow under personal protection.
