Please generate a highly polished image of a "daily poster / quote of the day / today in history." This is not an ordinary inspirational-quote image, not an information-dump image, and not a cheap template poster, but a high-end daily poster with mature aesthetics, clear layout logic, real reading value, and a refined atmosphere. The whole image must satisfy three things at once: 1. The image itself is beautiful — with atmosphere, texture, and a sense of design. 2. The copy itself is mature — with memorable points and room for interpretation, not childish, not juvenile, not like cheap inspirational fluff. 3. The information itself has substance, especially by adding the real information layer "today in history," so the image is not only good-looking but worth reading. [1. Overall character] - Refined, quiet, restrained, rewarding repeated viewing - With a clear magazine, design, and reading feel - The first glance conveys the atmosphere; the second naturally draws you into the text - Text and background must blend naturally, not just be pasted on - Overall with white space, breathing room, and rhythm - No e-commerce feel, no weather-app feel, no cheap inspirational feel, no childish healing feel [2. Background image] - Use a high-quality photographic-style background, not an ordinary illustration - The background should have blur, motion trails, soft focus, soft light, light grain, film feel, dynamism, or layers of light and shadow - The background's content, tone, atmosphere, and framing should intelligently match the input date and supplementary requirements - If the user provides a city, the city's character and weather state may be lightly woven into the background atmosphere or auxiliary information layer, but must not dominate the core copy - The background must be beautiful, clean, and alive, but must not steal the show [3. Core text system] The text across the whole image must form a clear hierarchical system, and all of it must be genuinely legible — not blurry, not garbled, not careless. It is suggested to automatically organize into the following levels: 1. Main title 2. Date module 3. Sub-copy module 4. Today-in-history module 5. English auxiliary small text 6. Weather information layer (added only when the user provides a city, and only as light support) [4. Main title requirements] The main title is the largest, most important, and first-seen text in the whole image. The main title copy must meet the following: - Absolutely cannot be childish - Cannot resemble juvenile fluff, corny social-media one-liners, or shallow comfort lines - Must have maturity, expressive tension, a memorable point, and room for interpretation - Must make people pause after reading, not be seen through at a glance - May carry a bit of mindfulness, insight, psychology, judgment, and restraint - Can be clever, but not greasy - Can be gentle, but not limp - Can have an edge, but not shout slogans - Don't say it all; leave an aftertaste - Avoid as much as possible clichés, excessive fluff, cheap encouragement, success-guru expressions The main title better suits these tendencies: - Like a polished, mature line of copy - Like a short line that can be savored again and again - Like a line with slight philosophy and mental tension - Like an expression that "seems calm but is actually very precise" The main title length should be moderate, concise and strong, not verbose. [5. Sub-copy requirements] The sub-copy is not an explanatory note for the main title, but the second layer of impact after the title. Sub-copy requirements: - Must read like copy, not like an instruction manual - No fixed sentence pattern, no same template every day - Must have emotional momentum, psychological trigger, refined logic - Can be 2–4 short lines, with varying length and a reading rhythm - Should form an echo, progression, contrast, or follow-up with the main title - Can lean toward mindfulness, cognition, insight, but must not become empty preaching - Can give the reader a sense of being understood, reminded, gently awakened - Must not be obviously dictated by the weather; weather at most affects the auxiliary information and image atmosphere, not the core copy [6. Date module requirements] The date module must be designed, not just a few numbers written casually. Requirements: - The date is the image's second visual anchor - Must have clear presence, but not be too heavy - More like a refined information tag in a magazine, not a calendar of large color blocks - A module feel can be formed through size contrast, offset, white space, thin lines, light borders, light grouping - Must clearly show: year, month, day, day of week, English month - The date module must be refined, clear, and elegant [7. "Today in history" module requirements] If the model supports online lookup, before generating, query "the today-in-history for the input date," then select from real historical events at least 3 most suitable for the layout. This module must satisfy: - Show at least 3 historical events - Must be based on real information, no fabrication - Prioritize: 1. Representative 2. Reading value 3. Easy to understand 4. Related to public awareness 5. Information concise yet weighty - Events need not chase the most obscure, but should be "suitable for reading in a daily-poster layout" - Each event is suggested in the form "year + brief event description" - The text must be concise and accurate, not written as a long encyclopedia paragraph - Can be presented as a list, small column, narrow column, side note, bottom news bar, etc. - This is a real information module and must not degenerate into decorative text Layout requirements for the "today in history" module: - This is the content layer, not the main visual layer - Cannot steal the main title - Cannot be made too heavy - Should appear as a refined, rational, lightweight reading block - It should enhance the image's sense of knowledge, time, and credibility [8. Weather information layer requirements] Only add weather information when the user provides a city. Requirements: - Weather information is only a light auxiliary layer - May show: city name, weather state, temperature range, and other brief information - Should look like a magazine side note or information tag, not a weather-app interface - Weather information must not affect the core expressive direction of the main title and sub-copy - It only serves to enhance the sense of time, life, and presence [9. Layout logic] Strictly follow mature layout-design thinking, not random text placement. Requirements: - Clear hierarchy: main title first, date second, sub-copy third, historical events and auxiliary layers fourth - Establish order through size, weight, letter spacing, direction, white space, alignment, and density - Use at most two font systems in the whole image - The main title font must have character; a modern serif, a Song/Chinese-serif character, or an elegant high-contrast title typeface is suggested - The body and information-layer fonts should be more readable — concise, restrained, clear - Don't misuse fonts, don't let styles clash - No large heavy color blocks, no heavy information boxes, no decorative pseudo-modules - There should be grouping relationships between modules, but borders should be light, thin, and natural - All text must be clearly legible, not too small, not blurry [10. Copy generation principles] If the user inputs only a date, still automatically generate complete content. Overall copy principles: - Main title: mature, restrained, memorable, with room for interpretation - Sub-copy: smart, refined, with a trigger, not template-like - English small text: short, restrained, genuinely legible, only as atmospheric support - Today in history: at least three real events, forming an information increment - If the user inputs other requirements, intelligently understand them and reflect them in the image and copy [11. Final image effect] The final image must achieve the following feelings: - First glance: refined, quiet, rewarding to look at - Second glance: strong layout, clear text relationships - Third glance: the main title is memorable, the sub-copy has aftertaste - Fourth glance: you can still see the real information value brought by "today in history" The whole image should look like a high-quality daily poster made by a mature designer, not a template randomly collaged by AI. Generate directly based on the following input: 2026-04-28 Beijing, Temple of Heaven the weather should also be prominent
