Can 12306 "change seats"? Official answer is here.

According to the "China Railway" official account, some netizens shared a tutorial on how to "change seats online" using a third-party ticketing platform, but is it really possible? The answer is no. The 12306 website does not have a function for changing seats online, seat changes must be done through exchanging tickets, and third-party ticketing platforms also follow the same process. Third-party platforms come with risks, so passengers are advised to use the official Railway 12306 app for online ticketing and ticket exchanges.
