"It occurred to me then that, if the opportunity arose, I would like to become a pediatrician," he says. It was a goal that was realized in 2015, when he was recruited by Hunan Children's Hospital after he graduated.

"Working as a pediatrician endows me with a sense of fulfillment every time I successfully save a child, as I know, to some extent, I save the whole family," Fan says. "Children also have better recovery and compensation ability, so that they can sometimes recover from heavy injuries that adults cannot, and they can recover to the extent that you can hardly find any trace of their former injuries. That gives me a lot of hope when I am trying to help them.

"I feel lucky to do what I am interested in, which is also meaningful, since it can help so many people. I want to spread that sense of luck with my patients," he says.
