Yu the Great Tames the Flood
Fifteen slides in Mao-era propaganda art with Simplified Chinese. One hero's face held consistent for the whole deck.
The Brief
15 illustrated slides telling the founding myth of 大禹治水 (Yu Taming the Flood) to Chinese teenagers. Simplified Chinese throughout. Mao-era communist propaganda art: heroic realism, sunburst compositions, dominant reds. The prompt was generated by PromptCoach.
Context
The art style is the test. Mao-era propaganda demands a visual vocabulary that most AI image generators default away from: heroic realism, low-angle framing, radiant sunburst backgrounds, muscular figures in idealized labor. The user picked it on purpose to stress the generator.
Three things break most generators. First, Yu's face and physique must stay consistent across all 15 slides. Same jawline, same build, same costume. Most models drift by slide 4. Second, Simplified Chinese characters must render correctly on every slide, in titles and body text. Not garbled. Not Traditional Chinese. Not Japanese kanji. Third, the compositions get hard. Slide 7 is a triptych: three panels in one illustration showing Yu passing his home three separate times without entering. Slide 6 shows hundreds of workers breaking mountains. Slide 8 is a disciplined formation passing rocks hand-to-hand.
The story itself carries weight. Yu spent thirteen years channeling floodwaters while his father's dam-building approach had already failed for nine. He walked past his own front door three times during those years and never went in. The first time, he heard his newborn son crying through the wall. He kept walking. The values, relentless labor (勤劳刻苦) and self-sacrifice for the collective (舍小家为大家), are baked into the narrative action on every slide. No slogans. No lecturing. Just a man digging ditches while his family waits.
The prompt came from PromptCoach. The user described what they wanted in plain language: the myth, the audience, the art style, the values to embed. PromptCoach produced a structured 20,000-character prompt with slide-by-slide instructions and art direction. That prompt drove the entire generation without further editing.
Trivia
One slide has Latin placeholder text leaked into the illustration — a known AI generation artifact. Calliope allows editing and regenerating individual slides to fix this, but there is no guarantee of identical output. AI generation is probabilistic: regenerate the same slide twice, get two different results. This presentation ships with the flaw visible. Users must verify every page.
What This Demonstrates
- —Character consistency held across 15 slides. Yu's muscular build, face structure, and bare-chested costume stay recognizable from the title card to the closing frame, including crowd scenes where he appears among hundreds of figures.
- —Simplified Chinese rendered correctly on all slides. Headlines (大禹治水, 三过家门而不入, 众志成城), body text, and annotations are legible, grammatically correct, and in the right script.
- —Triptych on Slide 7: three panels showing Yu passing his home at three stages of his journey. Newborn crying. Son who doesn't recognize him. White-haired wife and grown child. Each panel carries distinct lighting and emotional register. Most generators cannot plan multi-panel compositions.
- —Latin text leak left visible on one slide. A deliberate choice. AI-generated content requires page-by-page human review. Calliope provides per-slide editing and regeneration, but the output is never guaranteed.
