Is it possible to get on the plane from Harbin to Yinchuan? Is it possible to cancel the daily flights?

It should be said that the overall punctuality rate of flight 3U8878 from Harbin Taiping Airport to Yinchuan Hedong Airport is still relatively high, reaching 93.8%, but it is rare to see that it was delayed for nearly six hours due to the weather today. Because there is only one class, it may be delayed and it is generally impossible to cancel.
