Luobu, a 50-year-old doctor, rides on his horse heading for a sick villager's home in Nyemo county, Lhasa, capital of Southwest China's Tibet Autonomous Region, on Dec 10. Nyemo county is located 4,000 meters above sea level. Luobu takes care of health conditions of more than 370 residents of two villages in Nyemo county, which cover an area of 4 square kilometers.

Luobu continued his journey to another patient's home after seeing Baimu on Dec 10. The mountain road is so rugged that it is not suitable for driving motorcycles or other vehicles. The only way Luobu can cover the vast area is by horse. Regardless of rainy, snowy or blizzard weather conditions, if a villager needs his help, he will hit the road.

Luobu gives a physical examination of a 78-year-old woman Baimu on Dec 10. Baimu has hypertension and is unable to walk. Once she felt very unwell and gave an emergency call to Luobu at around 3 o'clock in the morning. Luobu hurried to Baimu's home overnight to treat her. "Luobu saved my life," said Baimu.
