“Rarely in world history has a single generation of brothers left so profound an imprint on a civilization's literature, politics, and philosophy as the six sons of Prime Minister Kim Su-hang—universally celebrated in Korean cultural history as the 'Yukchang' (六昌).”
1. The Six Brothers of the Jangdong Citadel
Raised in the literary haven of Jangdong at the foot of Mount Inwang, the six sons of Kim Su-hang each attained legendary distinction:
- 1. Kim Chang-jip (金昌集, 1648–1722 / Mongwa): Chief State Councilor and leader of the Four Noron Ministers.
- 2. Kim Chang-hyeop (金昌協, 1651–1708 / Nongam): Foremost Neo-Confucian metaphysician and literary theorist of late Joseon.
- 3. Kim Chang-heup (金昌翕, 1653–1722 / Samyeon): Revolutionary nature poet who pioneered the Korean True-View (*Jingyeong*) landscape poetry movement.
- 4. Kim Chang-eop (金昌業, 1658–1721 / Nogachae): Author of the celebrated Beijing travel diary Yeonhaeng Ilgi, a masterpiece of realistic travel literature.
- 5. Kim Chang-jeup (金昌緝, 1662–1713 / Poun): Master of classical prose and calligraphic arts.
- 6. Kim Chang-rip (金昌立, 1666–1683 / Takcheon): Prodigious youth poet whose early verses captivated contemporary scholars.
2. The Jingyeong Cultural Renaissance
Kim Chang-hyeop and Kim Chang-heup rejected rigid, formulaic imitation of ancient Chinese verse, advocating instead for the direct aesthetic celebration of Korea's native mountains, rivers, and vernacular emotion. Their literary circle directly inspired the True-View Landscape Painting (Jingyeong Sansuhwa) movement of master artist Jeong Seon (Gyeomjae).
