Just received a short message: China Southern Airlines flight CZ8 150 from Xiamen to Chongqing has been cancelled. Is that so?

Have you booked this flight? If you booked it, it should be that the flight was cancelled, and no one would be so bored. This kind of joke will usually inform the customer, then help you protect other flights, and then let you confirm. If you confirm it, you can directly tell the ticket issuing place or the airline to change it for you. If you don't want to take it, you can get a full refund!
