As the sole village doctor, Suo's work shift is day and night. "The closest town is over 20 kilometers away, it's easier for people to get medicines for small illness from me," he said.

For those who are impoverished or in difficult financial situations, Suo stated he won't ask for or accept any payment.

These days, Suo's movement is not as easy as before, but he still gives his all. When asked about the future, Suo said he can't live without the villagers, and they can't live without him.

"My heart aches whenever I think of how old uncle Suo has become. Our village cannot do without him. He saved my entire family and this year I was given a second chance at life thanks to him as well," said Jin Zhong, a villager seeking treatment.

"So long as these old bones can still move and be useful, I will do my utmost to help the villagers," Suo said.
