Do I need to pay for going back to Changchun isolation hotel?

This is a charge. If you need to isolate at your own expense, different hotels charge different fees, ranging from 150 yuan-600 yuan per day. The government usually designates a specific hotel as a local isolated hotel. You can choose a hotel that suits you, but it may be full and the scope of choice is too small. And you need to add your own money to eat.
