1.** Try to buy tickets by installments * *: If the direct tickets from Guangzhou to Changsha are sold out, you can consider buying tickets by installments. For example, first buy a ticket from Guangzhou to Shaoguan, and then transfer from Shaoguan to Changsha. This way may be a little troublesome, but it may help you get home as soon as possible.
2.** Use ticketing software * *: There are many third-party ticketing software, such as Ctrip and Qunar, which can provide more ticket source search and reservation services. Although this kind of software may need to pay or buy acceleration services, sometimes they can help you find available tickets faster.
3.** Pay attention to refund and change * *: 24 hours before departure is the peak period for ticket release and refund. During this period, the railway ticketing department may release a small number of reserved tickets, and many passengers will change their tickets or refund their tickets because of the change of itinerary, so we must always pay attention to the ticketing software, and there may be surprises.
Please note that the above suggestions do not guarantee that you will get tickets, but they are some possible solutions without tickets. Finally, it is suggested to buy tickets as soon as possible to avoid the situation that there is no ticket to buy.
