Chang Pyung-soon is a South Korean businessman, the founder and Chairman of Kyowon Group, a massive, diversified conglomerate with core interests in educational materials, publishing, and hospitality. Born in 1951 in Dangjin, South Korea, his early life was marked by extreme hardship: he was the eldest of seven children, raised in poverty by his grandparents, and suffered from malnourishment as a child.

His personal struggle fueled an intense drive for education; he graduated from Yonsei University. Despite initially attempting to become a civil servant, he failed the administrative examination, forcing him to pivot to entrepreneurship. He famously turned a modest cabbage sales business in 1980 into his first commercial success, quickly recognizing his natural talent for sales and management.

Chang Pyung-soon's entrepreneurial breakthrough came in 1985 when he founded a company (later developing into the Kyowon Group) focused on selling educational books and teaching materials. His strategic innovation was mastering the direct-to-consumer sales model for educational content, positioning the company to dominate the rapidly growing Korean private education market.

His earlier career saw him smash sales records at the publishing giant Woongjin, demonstrating his sales acumen. As the company scaled, he strategically diversified: in 2000, he began expanding the business by acquiring and developing real estate and building hotels, providing a stable asset base outside of the core educational materials sector. Today, the Kyowon Group is a multi-billion dollar giant, and Chang remains the Chairman, leading a diverse conglomerate despite his self-proclaimed introverted personality, often finding solace in hobbies like fishing and the game baduk.

Chang Pyung-soon's social impact is structural, stemming from the Kyowon Group's role in providing educational materials to millions of South Korean students. His company's success contributes significantly to the nation's highly competitive private education system.

His personal story, rising from poverty to a self-made billionaire, provides immense inspiration. His commitment to education and his active role in the publishing sector are major contributions to the intellectual life of South Korea.

Chang Pyung-soon maintains the dignified, reserved style of a traditional South Korean industrialist. His attire is consistently formal and professional, favoring tailored business suits. His aesthetic reflects his status as a leader in education and publishing, projecting stability and intellectual authority.

Residing in Seoul, his luxury is the profound security of his multi-billion dollar private fortune. His life is defined by his commitment to his founding company and his personal hobbies of fishing and the game baduk (Go), reflecting a quiet, contemplative inner life that contrasts with his immense commercial success.
