Chinese surveyors Zheng Lin (front) and Wu Guangwei conduct surveying at Mount Qomolangma base camp in southwest China's Tibet Autonomous Region on May 27, 2020. A Chinese survey team reached the summit of Mount Qomolangma Wednesday, and remeasured the height of the world's highest peak. After summiting at 11 a.m., the eight-member team erected a survey marker and installed a GNSS antenna on the snow-covered peak, which measures less than 20 square meters, while other surveyors conducted observations from six points beneath the peak.
