If you come across an 85-year-old woman walking slowly with a walker in the Children's Hospital of Soochow University, don't take her as a patient. Instead, she is a doctor who still insists working in the hospital.

Sheng Jinyun, born in 1935, a renowned expert in pediatric asthma, has treated about 30,000 children suffering asthma. She is known as "the most beautiful grandma doctor" by others. Currently, she still sees 40 patients every day.

Sheng has always stuck to her post despite suffering two fractures. A month ago, she began limping because of a fall. So now she can only walk with the help of walker.

"Others don't understand me. In their eyes, I'm supposed to live a peaceful life in this old age. But as long as I'm clear-minded, I can prescript well and make no mistakes. I want to cure more children," said Sheng.
