购买联程车票列车停运后怎么退票？_我的网站

一 |       购买联程车票列车停运后怎么退票？在联程车票开车前，登录铁路12306App，把停运车次车票和联程车票一起选中，手动提交退票。记住：必须一并退！ 如果只退停运段，剩下的联程票单独退，不仅会被核收退票费，还可能因为超时无法退。    (ECNS) -- An AI-powered “flying life ring” capable of autonomously reaching people in the water, keeping them afloat and returning to shore was demonstrated Aug. 6 at Xianghu Lake in Hangzhou, Zhejiang Province.    Chinese Foreign Ministry spokesperson Lin Jian recently shared footage of the device on social media, calling it technology that could help save lives.    During the drill, the orange ring flew from shore to a person in the water, shut down its propellers after landing, provided buoyancy, then took off again and returned to its starting point. Developed by Hangzhou police, the device uses autonomous navigation.    Other equipment demonstrated included drones that can drop inflatable life rings and an unmanned rescue boat that works with a drone to locate and bring people back to shore. Hangzhou police said the technologies are intended to shorten critical response times in water emergencies.    (By Intern Yang Hongran, Zhang Dongfang)                    。  作者：王瑞平、曾宣杰、钱依依、段凌云  画面来源：广铁集团  音视频部制作。
