Thank you very much for the question about the discount interval of student tickets ~ ~

According to the relevant regulations of the Railway Corporation and the Ministry of Education, the principle of selling student tickets is: the least number of passes and the shortest path.

From Kunming to Fuzhou, there is no through train. You have to change trains. In this case, student tickets can be purchased and used in stages.

In Kunming, buy student tickets with student ID cards; At the transfer station, use the student ID card and the student ticket used in the previous paragraph to buy the student ticket from the transfer station to Fuzhou.

So it is impossible for the landlord to buy a student ticket from Shanghai to Fuzhou. The reason for this is the following：

1. Based on the principle of short distance, it is impossible for the landlord to choose Shanghai as a transit point. If you choose a transfer station at random, then the landlord can go to Kunming-Beijing-Moscow-Ulaanbaatar ... Fuzhou. Isn't that a joke?

Even if Shanghai can become a transit station, the landlord can't buy a student ticket from Kunming to Shanghai or from Shanghai to Fuzhou.

12306 successful booking does not mean anything.

When booking tickets, you can't swipe your student ID card. The landlord needs to swipe his student ID card when he picks up the ticket. Once the purchased ticket is inconsistent with the travel interval recorded on the magnetic stripe of the student ID card, the landlord will not be able to pick up the ticket.
