Hangeul Day 100th anniversary poster with ChatGPT — King Sejong and Hunminjeongeum

Make **a vertical poster that celebrates 100 years of Hangeul Day** (한글날, October 9). Hangeul Day began in 1926 as 가갸날, so 2026 is its 100th year. The mood should feel like Hangeul Day: respect for King Sejong and joy in letters that anyone can learn.

**Picture — use what I write on the Picture line below**
- IMPORTANT: if the Picture line is empty, draw King Sejong (the first option). Draw no picture ONLY if I write 없음
- 세종대왕: King Sejong in a red royal robe with a dragon emblem and an ink brush in hand, painted in soft ink-wash style, seen from the side or slightly from behind, calm and thoughtful. Do not copy the 10,000 won banknote or any official portrait. Keep the face gentle and not too detailed
- 훈민정음 책: the open Hunminjeongeum Haerye book on a low wooden desk with an ink stone and brush, warm light
- 아이들: two or three children in hanbok writing Korean letters with brushes, smiling, seen from a little distance
- anything else I write: draw that, in the same ink-wash style
- any writing inside the picture (book pages, paper, signs) must be real, correctly drawn Korean letters such as 가 나 다 or ㄱ ㄴ ㄷ, or faint brush marks you cannot read. Never fake Chinese characters or made-up letters
- 없음: no picture, only letters

**Text — write exactly these Korean words, nothing more**
- top, small: 한글날 100주년
- the largest text: the words I write below. If I leave it blank, use these 3 lines:
  사람마다 쉽게 익혀
  날마다 씀에 편하게
  하고자 할 따름이니라
  and under them, small: 훈민정음 서문 현대어 풀이
- add 훈민정음 서문 현대어 풀이 ONLY when you use those default 3 lines. If I wrote my own words, do not add it
- bottom, small: 1926 가갸날 · 2026 한글날 (가갸날 is 가 + 갸; the second syllable is 갸 with the vowel ㅑ, not 가)
- if I write a name below (a school, a class, a shop, a family), add it in small letters at the very bottom. If I leave it blank, add nothing
- copy every Korean character exactly. Do not add, drop or swap any syllable, and do not "fix" the spelling. No English anywhere

**Look**
- the largest text in the old woodblock print style of the Hunminjeongeum Haerye book (판본체): thick, even strokes, square shapes, ink a little uneven like a real print. Small text in a clean, simple Korean font
- warm off-white hanji paper with faint fibers, mostly black ink, soft muted colors only in the picture, and one small deep red seal stamp
- the picture and the text never overlap; the text stays easy to read
- portrait 2:3, plenty of empty space, dignified and warm, like a poster in a museum shop. No cartoon style, no flags, no shiny 3D

Make one image. Then, in one short Korean line, tell me every Korean line you wrote, so I can check each letter before I print or post it.
