Zhang Yanmin, 27, a ticket seller in Baoji, Shaanxi province, helps rural seniors to purchase train tickets.

I was born and raised in a rural family in Fufeng, a county in Shaanxi province.

When I was young, my parents took me to visit relatives and friends in other provinces. We always took the train, so my parents went back and forth to the train station for several days to get tickets. It was an exhausting process.
