For many of us, work is a matter of busting our backsides just to get by. But there are others for whom work is not only something they enjoy but a whole way of life. Banknote engraver Sun Wen-hsiung is one such lucky soul. After spending some 50 years working for the Central Engraving and Printing Plant, the skills he developed in the course of his career became more than just work for him, to the point that even in his retirement he continues to put them to creative use.
