I heard that trains have private rooms, but the reasons why you may not be able to purchase private room tickets directly on your mobile phone are as follows:
Ticketing policy restrictions: The train ticketing system may not provide online purchase services for private room tickets due to policy considerations. This may be to ensure that the booking and distribution of private room tickets is more equitable.
Ticket source allocation: The ticket source for private room tickets may be relatively limited. In order to ensure that all passengers have a fair opportunity to purchase, online purchasing channels may not be provided.
Complex operation: The purchase of private room tickets may involve additional steps, such as selecting the type of private room, confirming the number of guests, etc. These steps may be relatively complicated to operate on a mobile phone.
System function limitations: At present, the functions of the train ticketing system may not be perfect enough to directly purchase private room tickets.
It is recommended that you purchase private room tickets through the following methods:
Go directly to the train station: Go to the ticket window of the train station, consult the staff and purchase private room tickets.
Telephone purchase: Dial the railway customer service number and book private room tickets over the phone.
Waiting for system update: Pay attention to the update of the train ticketing system and wait for the online purchase of private room tickets that may be available in the future.
