According to China Railway Beijing-Shanghai, Beijing-Guangzhou, Chengdu-Chongqing High-speed Railway and other Fuxing EMU trains, silent carriages have been installed.
How to buy silent carriage tickets? When you open the Railway 12306 App and set the silent carriage, the train number will have the word "quiet" as a prompt.
If you want to purchase a second-class ticket with the word "quiet" in it, you can check the option below "Please assign me a silent car seat first"
After reading the warm reminder and clicking "Confirm" and submitting the order, the system will automatically allocate silent carriage tickets if there are remaining tickets.
