Ru Zhigang has 3 certificates for climbing Mount Everest, but the 3 certificates mark 3 different "heights" of the world's highest peak. On May 1953, 5, New Zealander Edmund Hillary and Nepalese guide Tenzing Norgay climbed Mount Everest from the southern slope, achieving the first human ascent to the summit.
This year marks the 29th anniversary of that feat. The team originally planned to reach the summit on May 5, but due to the weather, they had to stay in the C19 camp (2 meters above sea level) for four days.
