    Sitting on the “Roof of the World”, Mount Qomolangma National Nature Reserve is one of the world’s hotspots for biodiversity protection. Mount Qomolangma, also known as Mount Everest, is to be measured again by a Chinese team to make sure its exact height after last official measurement.

“Conducting research and protecting the region can help us learn more about the origin and development of the earth, as well as our human-beings and wildlife,” said Cheng Pengfei, president of the Chinese Academy of Surveying & Mapping (CASM).

The weather in the Mount Qomolangma area changes frequently. While the maximum temperature in the tent is more than 20 degrees Celsius, or even 30 degrees Celsius at noon, it may start snowing in the afternoon, and a gale may spring up at night, even blowing away the tents. Those taking part in the mission are ready for the task after preparing thoroughly at the base camp.

The complex geological environment has formed diverse landforms in the area. Distinctive snow mountains, valleys, rivers, lakes and glaciers can be found. And the unique ecological environment has also established a special biological diversity.
