Why didn't the high-speed rail refund the ticket within 24 hours?

One of the following reasons may be that the refund of high-speed rail within 24 hours is not deducted:

1. Cause of the epidemic: the station was temporarily closed, resulting in the cancellation of the refund fee.

2. Weather: Due to the weather, some trains are temporarily suspended, and the refund fee is waived when the ticket is refunded.

3. Adjustment of train diagram: Due to the adjustment of train diagram, the train can't run normally, and the refund fee will be waived when the ticket is refunded.

4. Train failure/temporary adjustment of marshalling: Due to train equipment failure or temporary change of trains from long marshalling to short marshalling, the refund fee is exempted.

5. Affected by different trains on the same line: Due to the influence of different trains on the same line (such as long-distance running and short-distance stopping), the refund fee will be waived when refunding tickets.

It should be noted that the reason for the refund is that if the passenger cannot travel on time due to illness, the refund formalities will be handled online within 2 hours after driving at the latest.
