He has summited Mount Everest ten times (including four times from the Chinese side) and is recognized as one of the strongest climbers in the Himalayas and a world-renowned mountaineer. He managed to set two world records on Mt. Everest during the spring season by spending more than 21 hours on the summit of Mount Everest without oxygen (still a record), and by climbing the Mt Everest from the south side for the fastest time in 16 hours and 56 minutes. Unfortunately, he died on April 29, 2001, during his attempt to climb Everest for the 11th time.
