"Inspiration comes from life. I always find that passengers have misunderstandings about train travels, often resulting in them missing their trains. That's why I decided to collect ideas and make short videos to publicize travel knowledge in my own spare time," said Yu.

"I hope to teach knowledge in a down-to-earth approach and ensure the travel safety of passengers," Yu added.

In the ongoing Spring Festival travel rush, there are 135 young staff members also born after 2000, like Yu, working in Chongqing North Railway Station depot. All of them contribute their efforts to the safe, orderly and warm travels for passengers in their own posts, protecting their way back home with actions.
