In 1979 my father-in-law Tom Norcross went to Hong Kong with his family to coach fencing. He was there for 15 years. Part of the brief was to set up a self-sustaining fencing programme. Unlike other expat coaches, he learned Cantonese and grew the talent of local coaches as well as fencers.
My wife's family are proud that he contributed a small part in the success of Hong Kong's recent fencing gold.
