In Burjin County, Altay Region, Xinjiang, the northwestern border, the postal deliveryman Muhamaitibuik Muhamaitihali traveled to the mountains and rivers every day to deliver letters and parcels on time.

This postal route has a long mileage and a round trip of 448 kilometers. The road conditions are complicated and the terrain is dangerous. On this postal route, Muhamaitibuik encountered various difficulties: the vehicle was shut down in extremely cold weather, the road was trapped in an avalanche and the mountain was trapped in the mountains... Faced with unknown dangers, he never thought of giving up.

In recent years, with the rapid development of the tourism and e-commerce industries, local herders have lived a better life. Muhamaitibuik still sticks to his post, measuring the mountains with his feet, connecting people's hearts with postal routes, and witnessing the development of the border.
