As Xizang commemorates the 75th anniversary of its peaceful liberation, high-quality development is creating new opportunities for younger generations across the plateau. Our reporter Huang Yue introduces us to a young entrepreneur on an environmental mission, using livestock waste to heal the grasslands and boost local incomes.

On the windswept grasslands of northern Xizang, the sight is familiar: piles of dried yak dung stacked along walls, used as fuel for cooking, and surviving long, frigid winters.

But to one young man, this isn't waste. It's untapped potential.

HUANG YUE Nagqu, Xizang Autonomous Region "This is what pastures at 5,000 meters above sea level look like, absolutely breathtaking. Most people would probably stop here for photos, but not us. We're here to collect yak dung!"

"The dried yak dung is what we are looking for, right?"

"Yes, the dried ones like this one."

"This one too."

Tsering Migyur launched his business in 2017 by doing something few imagined: collecting livestock waste across the plateau and turning it into organic fertilizer.

TSERING MIGYUR Young Entrepreneur in Nagqu "The first challenge was technical. I didn't know how to ferment or process it into fertilizer. The second was tradition. Many elders saw dung as a blessing. Asking to buy it felt like asking to take away their good fortune."

Migyur went door to door, explaining how selling the dung could generate income without losing that sense of connection to the land.

Today, over 20 collection stations across Nagqu form part of his network. Some herding families can earn between 1,400 to 2,000 US dollars a year, just from selling dung.

Many who once hesitated now call him directly, asking him to come and collect it.

CHOSYING WOESER Herdsman "Times have changed. Since he built the factory, we can sell our yak and sheep dung. It brings in extra income, and now we eagerly await his arrival."

Migyur's growing business has also created dozens of local jobs, from collection site managers to drivers and factory workers.

TSERING MIGYUR Young Entrepreneur in Nagqu "The factory covers 13,000 square meters. This spring, we collected over 4,000 cubic meters of yak and sheep dung in total. Right now, we're working with the Chinese Academy of Environmental Sciences to experiment with new fertilizer formulas."

Born and raised on the plateau, Migyur's ambition goes beyond business.

He has been working with scientists to use these fertilizers for ecological restoration, trying to bring grass back to degraded lands and heal the fragile highland ecosystem.

TSERING MIGYUR Young Entrepreneur in Nagqu "Nagqu is known as Asia's water tower. Someone needs to protect it. If I can do that within my abilities, then future generations will benefit. That's what makes it meaningful. I believe there's philosophy in the stars, there's philosophy in yak dung, too."

Migyur is working on two new ideas as a heartfelt tribute, where tradition meets sustainability.

TSERING MIGYUR Young Entrepreneur in Nagqu "We throw prayer flags into the wind during festivals. I'm thinking of developing biodegradable ones made from yak dung, so they won't pollute the grasslands. I'm also working on a fertilizer that wraps grass seeds inside, so when drones spread it, the seeds can germinate with the rains."

On the Roof of the World, transformation doesn't always come in big, flashy breakthroughs. Sometimes, it begins with the smallest things, the things others leave behind. Huang Yue, CGTN, Nagqu, Xizang Autonomous Region.
