🏹📜 The Genius King Sejong Cherished Most Was Not Jang Yeong-sil | Lee Cheon, the Genius Military Officer of Joseon We always think of 'Jang Yeong-sil' as the greatest scientist of Joseon. However, did you know that there was a different true commander who selected Jang Yeong-sil, directed him from above, and whom King Sejong ordered the Crown Prince to "learn from this man"? 🤔 ⚔️ A military officer who crossed the Amnok River to conquer the Jurchens 📖 The master of printing who cast 200,000 'Gabinja' movable type 🔭 The head of the astronomical project who oversaw the Honcheonui, Ganyeodae, and Angbuilgu 💰 The Minister of Finance who standardized weights and measures and managed the nation's treasury A man who drew borders with a sword and molded characters with molten iron. We are properly restoring the life of Lee Cheon, the 'prodigy' of Joseon who single-handedly did the work of six or seven people, for the first time in 600 years. 😮 If you watch this video to the end, you will see the real picture of how the common belief that "Jang Yeong-sil was the greatest genius of Joseon" is a myth, and why Yi Cheon was relegated to a footnote. ✨ 👍 If you enjoyed this video, please like, subscribe, and turn on notifications to stay tuned for the next story! 💬 If you have discovered any new "hidden historical figures," please let us know in the comments. 📚 References ▪️ Annals of King Sejong*, *Annals of King Munjong (National Institute of Korean History, Annals of the Joseon Dynasty DB) ▪️ Jeon Sang-un, *History of Korean Science and Technology*, Jeongeumsa ▪️ Encyclopedia of Korean Culture, "Lee Cheon" (Academy of Korean Studies) ▪️ National Institute of Korean History, Woori History Net, "Conquest of the Jurchens," "Observational Instruments of Ganyeondae" ▪️ Compiled by Yi Sun, Seojeongnok — Records of Lee Cheon's Conquest of Pajeo River and Establishment of the Four Garrisons #LeeCheon #JangYeongsil #KingSejongTheGreat #JoseonHistory #Gabinja #Honcheonui #4Guns6Fortresses #PajeoRiverConquest #JoseonScience #KoreanHistory #TheTrueGeniusKeepedBySejong #ThePersonWhoDiscoveredJangYeongsil #LeeCheonTheGeniusMilitaryOfficial #TheCreatorOfGabinjaMetalMovableType #ChiefOfAstronomicalInstrumentsOfJoseon #PajeogangJurchenConquestCommander #CompleterOfJoseonPrintingTechnology #RelationshipBetweenSejongAndIcheon #JangYeongsil'sSuperiorIcheon #TheBrainOfJoseonHiddenByHistory ⚠️ Copyright Notice: The copyright for all content of this video, including the script, editing, and narration, belongs to this channel.
