But it is impossible to predict the change of K 10 10 times. First, the passenger flow is relatively concentrated during this period.

With the dense passenger flow, it is difficult for passengers to get on the train at the station, which may lead to the delay of passenger train departure;

Second, a large number of passengers are running now, the railway transportation capacity is in a state of supersaturation, and the difficulty of train operation adjustment is obviously increased;

Thirdly, when the peak weather in Spring Festival travel rush is cold,

Complex and changeable weather will also have a certain impact on the train operation order, leading to delays.

So planning is not as good as change, but you can't cope with change without planning, so I suggest you plan early.
