Does Huaibei isolation have to be at its own expense?

If the government arranges it, you don't need to pay at your own expense.

If the local government department requires centralized isolation, the expenses incurred during the period shall be borne by the local government department. If people who have close contact with people diagnosed in COVID-19 need centralized isolation, and usually in a specific local hotel, then the isolation period is at least 14 days, so high accommodation and meals will be incurred during the isolation period.

The expenses arising from home isolation shall be borne by oneself. However, policies in different regions may be different, and local policies shall prevail.
