92-year-old Feng Keyan, is one of the first-generation of western medicine doctors in China.

A graduate of Shanghai Tongji Medical University, Feng has dedicated herself to providing medical services for some 60 years. She's also an academic and plays one of the leading roles in China's field of geriatric studies.

After retiring in 1992, Feng was re-employed by a hospital, offering appointments three days a week.

Rushing to the hospital after a quick breakfast...That's her daily routine when she's on duty.

It's 8'o clock in the morning.

Feng has already put on her uniform and is waiting for her patients.

In order to understand her patients' conditions better, Feng is always meticulous about every tiny detail of their descriptions.

and sometimes, she even knows her patients' health conditions better than they do...

"Thanks to doctor Feng, I got my illness cured in time. At first, I myself didn't even notice the problem. She's very nice. She always listens to me patiently, and she helps me to analyze my health. She can see what other doctors might ignore," patient He Jianguo said.

Though all of Dr. Feng's patients speak highly of her professionalism, in her own point of view...she still has to work hard in order to be a better doctor.

"Sometimes patients are our teachers. We can learn a lot of new things from their descriptions. I keep reminding myself that, as a doctor, I have to treat my patients seriously and always improve myself," Dr. Feng said.

Perhaps for her...It's never too late to be a better and more dedicated doctor.
