On the 28th, many netizens posted that when logging in to the China Railway Jixun App (formerly Pocket High Speed Rail) to connect to the high-speed rail WiFi, the indecent phrase “X your mom” appeared in the system popup window. Other netizens claimed that the curse “X your mom” also appeared when the China Railway Jixun app performed real-name authentication. On the morning of the 28th, the 12306 customer service staff told the China Railway Jixun App that the China Railway Jixun App is indeed 12306 officially authorized software. As for the problem of indecent language in the system popup window, 12306 was unable to handle this issue because it did not belong to the same section. The reporter was advised to report it to the official customer service of the China Railway Jixun App. The General News reporter called China Railway Jixun App's official 400 customer service number several times, but none of them answered. At around 13:00 on April 28, the reporter from Overview News downloaded the China Railway Jixun app through an Apple phone. The swear words “X Your Mom” also popped up during real-name authentication. The reporter switched to an Android phone and downloaded the China Railway Jixun app again for real name authentication, and no indecent language popped up. (Overview of news clients)
