"A Small Key Opens Big Doors'' is a remarkable story told in Kim Hyang-Soo's own words about how he, together with the people he most cared about—his family, teachers, employees, colleagues, and customers—lived through good times and bad on his way to creating and managing one of the most outstanding endeavors the world has known. What is so remarkable about Honorable Kim Hyang-Soo is the fact that, despite all of his accomplishments as an industrialist, politician, and calligrapher, he remained humble, as can be seen throughout the pages of his autobiography. His humility is awe-inspiring, considering the fact that he was one of the key contributors to the economic miracle of Korea.
