Chinese mountaineers reached the peak of Everest

A group of Chinese climbers reached the peak of Everest. The athletes want to redefine the height of Jomolungma. It took four hours to climb from 8,300 meters. Eight climbers are installing geodetic equipment and a GNSS antenna. Scientists believe the height of Everest could have changed five years ago. The mountain massif could have been transformed by an earthquake in Nepal.
