A Chinese scientific expedition is working on Mt. Qomolangma to conduct China's second scientific research survey of the Qinghai-Tibet Plateau.

The new comprehensive scientific expedition on the world's highest peak is the country's first scientific research above an altitude of 8,000 meters on the mountain.

More than 270 scientific research members from five teams are participating in the expedition.

Last week, 13 members of the expedition reached the summit of Mt. Qomolangma at a height of 8,848.86 meters.

The squad established an automatic meteorological monitoring station at an altitude of 8,830 meters, the world's highest of its kind.

They also measured the thickness of ice and snow using high-accuracy radar and collected samples for further research at the summit.
