Editor's note: This year, the People's Republic of China celebrates its 75th anniversary, marking a crucial year for achieving the goals and tasks outlined in the 14th Five-Year Plan (2021-25). China Daily is publishing a visual series focusing on the high-quality development of various fields, capturing the process of Chinese-style modernization through photographic images. This week, we are highlighting a herder's family who lives at the source area of the Yellow River.

Often referred to as a "mother river" by Chinese people, the Yellow River frequently impresses sightseers with its grandeur.

Yet at its source area in Qumarleb county, Qinghai province, the scene looks vastly different. Here, the water that feeds the mighty Yellow River is just a creek, where streams gurgle through the ground.

This is the place where Karchug resides.

The 37-year-old Tibetan herder's family has lived a mere 3 kilometers away from the river's source, at Yoigilangleb Basin, for generations. At 4 am each day, Sodnamkyi, Karchug's elder sister, goes to the river to collect water for the family and their yaks.

Apart from being a herdsman, Karchug has a more significant role — serving as the river's "first guardian". At his house, a stone pillar is inscribed with the characters "Yellow River's first outpost", and he devotes himself to fulfilling his protection duties.

Riding his motorcycle, he carries rations with him as he embarks on his daily patrols, recording the activities and major changes among the wildlife, plants and snow line.

Karchug told China Daily that ever since he was young, his parents have instilled in him the importance of taking care of the environment, as life along the river would suffer if the river was polluted at its source.

He has passed on this duty to his children. These days, whenever they have school holidays, he takes them to pick up garbage in the area. He said he will continue to promote this responsibility to them so that they will continue this work in the future.
