Yang is the only postman there. In order to get to the office from his home on time, which is over 30 kilometers away, he has to get up at around 5 a. m. on workdays. Before leaving, Yang sorts the parcels in his post office. As an experienced postman, Yang can complete his sorting in just about 30 minutes. He has to ride more than 70 kilometers along the mountain road for nearly three hours to complete his work.

When the parcels need to be delivered right away, he will always find a way to deliver them to the villagers, even if he goes there on foot, regardless of the bad weather. In 2007, when Yang was new, the road was not completed, so he had to deliver the parcels on foot for nearly one year. "The bags weighed about 35 to 40 kg and I had to carry them, walking over 30 km a day." said Yang.

Before Yang started his job, his elder brother and father had also been postmen working there since the late 1990s. Together with Yang, his father and brother have provided delivery services there for over 20 years.

So far, Yang has traveled more than 40,000 kilometers and worn out four motorcycles. Although the trips were hard. Yang said he got such a strong feeling of satisfaction when he saw the smiling faces of the villagers after they received their parcels.
