As the summer holiday ended and large numbers of children travelled home, the Hangzhou train crew of the Baotou Passenger Division under CR-Huhhot launched the "Safety First, Happy Journeys for Children" initiative. On board, conductor Kong Xiangrui acted as a "safety mentor," patiently explaining safety knowledge cards, displaying railway safety bulletins, and promoting safety awareness. The initiative helped ensure safe and enjoyable travel for children while demonstrating the responsibility and care of railway staff.
