Due to the complicated natural conditions of the world's highest peak Mount Qomolangma, yak conveyance has become an essential means of transporting goods and materials for scientific expedition to Mt. Qomolangma.

Herdsmen living in Zhaxizom Township of Tingri County, the nearest administrative township in China to Mt. Qomolangma, have been providing yak services to climbers in response to demand. The herdsmen's work of yak conveyance usually starts from walking the yaks onto the Mt. Qomolangma base camp at an altitude of 5,200 meters. Then they load these yaks with goods like oxygen cylinders and tents before heading for advance camp at an altitude of 6,500 meters on Mt. Qomolangma.

This year, Chinese scientists have started a scientific expedition to the Mt. Qomolangma region in southwest China's Tibet Autonomous Region, as part of the second comprehensive scientific expedition to the Qinghai-Tibet Plateau.

Palden, a herdsman living in Zhaxizom Township, has been helping scientific research team members transport goods. A nine-day round trip would make Palden earn more than 4,000 yuan ($ 569). Besides transporting goods and materials, herdsmen here also take a responsibility to pick up rubbish along their route back to the foot of the mountain. "There is only one Mount Qomolangma on the earth and it's our obligation to well protect her," said Palden.
