A 20-year-old Hong Kong man has become the youngest person from the city to climb the highest mountain on each of the seven continents.

Bob Tsang began his journey when he was just 13 years old, starting with Mount Kilimanjaro in Africa, which stands at 5,895 metres above sea level.

Over the years, he has climbed Mount Everest in Asia, Mount Aconcagua in South America, Mount Denali in North America, Mount Elbrus in Europe and Puncak Jaya in Oceania.

Last Saturday, he finished climbing Mount Vinson in Antarctica, completing his journey to climb the Seven Summits in seven years.

His father, John Tsang, a professional mountaineer, achieved the same feat in 2012.
