"The top of the yurt has a skylight for ventilation and lighting, which can be covered during rain," Ban says.
In 2008, the craftsmanship was listed as a national intangible cultural heritage.
Additionally, yurt construction techniques integrate woodworking, embroidery, carving, painting and weaving.
"The patterns are mostly of clouds, grass and animals for decoration," Ban says.
Wood, rope and felt are chosen because they are readily available on the grasslands and render the yurts lightweight, portable and reusable, which makes for convenient construction, dismantling, relocation and repairs, Ban explains.
In 2012, his younger brother Ban Fenggong quit his job at a local State-owned company and joined his cause in establishing a yurt production facility.
It was a decision from Ban Fengbin's influence and the market potential.
