Intrepid expedition leader Wilson Cheung makes the world his home
Hongkonger leads tour groups through the frozen polar wilderness - but despite his adventures, he never forgets his friends and family in the city

Hongkonger Wilson Cheung Wai-yin has scaled some of the world's most perilous mountains and led expeditions to the planet's most desolate spots. But one thing scares him more than the very worst that nature can throw at him: human behaviour.
Cheung has spent the last two years travelling the world in a variety of jobs, including leading groups to the Arctic and Antarctic, and working as a climbing guide in Germany, Austria and Switzerland.
"I don't have a permanent home now," the Baptist University graduate says. "The earth is my home."
Cheung first went to Antarctica in 2007 as a student in an expedition organised by an American environmental group.
But after graduating with a degree in physical education and recreation management, Cheung struggled to find a job.
"I had been searching for one for six months," Cheung said. "But no one wanted to hire me. Some friends said my résumé might look too good."
