But be sure to pay attention to the time of ticket collection. If you buy it before the departure time, you won't get it. For example, if you want to go to Shanghai from Shijiazhuang and buy a ticket from Beijing to Shanghai, you must pick up the ticket before the departure time in Beijing and get on the bus in Shijiazhuang.

Also note that student tickets must be within the scope, otherwise you won't get them at many stops.

Extended data:

"Get on the train first and then make up the ticket" generally means that in China, passengers get on the train without a train ticket, and then buy a train ticket on the train. This situation is more common in Spring Festival travel rush peak, going out to work, and when college students start school. Because the current situation in China is a large population and train tickets are tight, many people can't buy train tickets because of scalping, so many people take the method of getting on the train first and then making up the tickets. But in some big stations, this method is more difficult because of strict management.

In foreign countries, this situation should not be much, because of the small foreign population and other reasons.

Of course, it is not static, and the meaning of "get on the bus first and then make up the ticket" has also changed and expanded.
