Despite seeing friends lose their lives to the mountains, one Hongkonger is facing his fears - and has just conquered Mount Everest for a second time.
John Tsang Chi-sing has been climbing mountains for 22 years.
In 2009, he was the third person from Hong Kong to scale the 8,848 metres to the summit of Mount Everest.
This year, the 60th anniversary of man's first ascent of the mountain, he has done it again.
"The death rate [of people trying to conquer Everest] is about 8 per cent … but there was a sense of spiritual satisfaction when I reached the top," he said.
Tsang set off from Tibet on April 7, reaching the top of the mountain 49 days later.
It was as challenging as the first time. He said he had to carry about 10kg of equipment, including oxygen tanks.
