How to buy the lower berth of train ticket by SMS?

12306 You can't choose bunk beds to buy tickets, but you can continue to try. But only three times a day, everyone can book tickets at 12306, and the bunk beds are given randomly by the system. However, each account has two chances to cancel the order. So when you submit the order and find that the berth given by the system is not what you want, you can cancel the order and re-submit it, and the system will regenerate a new berth. But it can only be cancelled twice, and the third time must be confirmed.

The itinerary conflicts with the account of the purchaser or is temporarily blocked.

If a large number of tickets are purchased with the same account and ID (generally above 10), his account will be temporarily "locked", and even tickets purchased by others with his account will be "locked" at the same time. The account holder can only return, change and pick up the ticket after "unlocking" the manual window of the station with the identity certificate.

If you need to "unlock" at the station window, you will be notified by SMS or email, telephone 12306. In the process of unlocking, passengers may be questioned by the railway police. Only by removing the suspicion of scalping tickets can the normal account use function be restored.

12306 upper berth cannot be selected manually. Only by submitting the booking and entering the payment page can you see whether it is the upper berth, middle berth or lower berth.

If there are special circumstances, you must choose bunk beds:

4. Return all five cards. I bought it again, and this time I bought one, because the second one is the lower berth.

5. Log in and buy with another account, which is the lower berth.
