A video clip showing a gray-haired doctor operating a computer carefully and checking the data meticulously moved many netizens, People's Daily reported.

Zhang Fusheng, an 87-year-old practitioner from Lishui, Zhejiang province, has devoted his whole life to patients. Though he retired in 1996, he chose to remain at his post. "If I can do something for the patients, I'll always do it," said Zhang.

In his more than 70-year career, Zhang has adhered to rational drug use and avoided unnecessary examinations. "Providing highly efficient and cost-effective medications for patients is my guiding principle," said Zhang.

Six years ago, Zhang signed up to donate all his organs to the Red Cross Society of China after his death. "I love my job. I believe that everyone should love what they do," Zhang added.
