Cheonjamun (千字文) is a 6th-century Chinese poem of 1000 unique characters, grouped four-by-four, telling of life, nature, and history.
In the AI era, Hanja literacy is fading. ONGO proposes the slow path: one character per day for 1000 days — the way 6th-century scholars learned it.
Today is Cheonjamun Day 39. Catch up via view all 1000.
