Excuse me, my bus interval is from Yinchuan to Chongqing North Railway Station, but now I want to go from Dazhou Station to Yinchuan, the first two stations of Chongqing West Railway Station

Enjoy student tickets. The interval written on the student ID card is Yinchuan and Chongqing, so you can only buy student tickets according to this interval. Buying Yinchuan student tickets from Dazhou will not work.

Theoretically, you can pass through Dazhou from Chongqing to Yinchuan, and you should be able to buy student tickets, but the railway ticketing system shall prevail. I can only say "you can try" - if the railway ticketing system prompts that the boarding interval does not match, it will not be issued Tickets may have to re-plan the itinerary. (for reference)

You can enjoy it, but you can only buy it once. Get a good ticket in advance and buy it with your student ID card.
