Two decades of hard work made the doctor a "guardian angel" for Wuqang villagers.

NGARI, Aug. 6, 2019 (Xinhua) -- Born in 1979, Zhoima has been a village doctor in Wuqang for more than 20 years.

The village is located in Rutog County, Ngari Prefecture of southwest China's Tibet Autonomous Region.

Unlike most other places in the country, it's not an easy job to be a doctor here considering its weather and high altitude.

It is estimated that each year she provides more than 600 diagnoses and treatment to villagers regardless of the weather and journey.
