"The ultra-high altitude comprehensive scientific expedition in the Qomolangma area is a feat of humanity," says Yao Tandong, an academician at CAS and team leader of the second scientific research survey of the Qinghai-Tibet Plateau.

Following the team's summit on May 4, scientists and researchers cheered and clapped inside the expedition's headquarters at the Mount Qomolangma base camp. Outside the camp, Tibetan snow cocks that often visit the camp crowed, reverberating across the valley.
