Tickets booked by Ctrip plus hotels are non-refundable. What if the flight is cancelled?

Alas, the airline can be responsible for returning and changing the visa, but you can only bear the loss of this hotel reservation yourself. You can only refund or change your ticket at the airline counter at the airport. Since the flight has been cancelled, you don't need to pay the difference or change your ticket. The airline will arrange a change or refund for you.
