Spring Festival travel rush craze began to add money to ticketing software. Why is it hard to get a ticket?

Spring Festival travel rush's ticket grabbing is not finished at once, but in batches every day. It's sold out today, and we need a small part tomorrow. The number of carriages on the train is due to the need to add carriages during the peak hours in Spring Festival travel rush, and this part of the tickets are also sold in the later period, so although the ticketing software adds money to grab tickets, the number of tickets is limited.

Train tickets in rush, Spring Festival travel rush are not the same as in the past, or some people say that 2008 is like a great immigrant. In order to meet the travel requirements to the greatest extent, it is common to add a carriage and change the hard sleeper into a hard seat at the peak of Spring Festival travel rush. How many tickets are sold every day also needs to be counted in the background, and then you can see how many tickets are left, and how many tickets have been added for temporary addition and transfer. There are two main ways to go, online ticket purchase and queuing ticket purchase. Most people have completed most of the ticket purchasing process because they can use mobile phones. A small number of people can't get tickets because they can't play mobile phones, but the number of tickets given is uneven. Online tickets are sold out, and most people can queue up to buy tickets, which shows that the tickets given in the background are different, mainly queuing. Online tickets can be refunded when they are sold out. At this time, it is time to test the strength of the ticketing software, but there are also cases of network speed. If the network speed is not good, the ticket is also limited.
