Chinese Lichun Solar Term Poster

Goal: Create an elegant Chinese solar-term poster for {argument name="solar term" default="立春"}, combining traditional gongbi painting, ink-wash landscape aesthetics, and a refined editorial calendar layout.

Canvas: Wide horizontal poster, 16:9 ratio, warm ivory handmade rice-paper background with subtle fibers, faint creases, and very light beige texture. Overall palette is restrained: ink gray, muted olive green, pale peach pink, soft brown, and vermilion seal red.

Layout: Center the composition around a large minimalist Chinese title “立春” at the top, written in thin, elegant Song-style calligraphy strokes. Beneath the title, add a small poetic line: “律回岁晚冰霜少  春到人间草木知”, with a smaller centered caption “中国传统节气”. Below this, place a large arched window frame occupying the lower two-thirds of the poster, containing the main gongbi landscape scene. Keep generous negative space around the text and illustration.

Main illustration inside the arch: Paint a delicate early-spring thawing landscape in traditional Chinese fine-line style. Include exactly 6 major natural elements: 1) a flowering plum branch entering from the lower left with pink blossoms and many buds, 2) pale gray distant mountains in mist behind the branch, 3) melting snow and ice along a shallow stream, 4) a small mound of dark earth in the center with two fresh green shoots emerging, 5) drooping willow branches with new leaves hanging from the upper right, and 6) one swallow flying near the upper center-right. Use fine brush lines, translucent watercolor washes, and realistic gongbi detail, not cartoon style.

Left information block: In the upper left, set small vertical-style Chinese informational text in gray ink. Include exactly 5 text items: “二十四节气”, “之立春”, “2025 / 02 / 03”, “农历正月初六”, and “斗指寅·太阳黄经315°”. Under the date, draw a small horizontal ruler-like scale labeled 0, 15, 30, 45, 60.

Right information block: In the upper right, draw a thin vermilion circle seal containing four stacked characters “立春 / 节气”. Below it, add a lifestyle tips block titled “生活提示” with a small red seal mark, followed by exactly 4 short phrases arranged in two columns: “早睡早起”, “顺应自然”, “多食辛甘”, “助阳养肝”, then a final line “适度舒展  心怀温暖”. Along the far right side, add a vertical seasonal notes column with exactly 4 items separated by short red divider lines: “东风解冻”, “蛰虫始振”, “鱼陟负冰”, and one additional thin divider line for rhythm.

Seals and details: Add one small square vermilion artist seal near the lower left of the arch. Keep all typography thin, refined, and balanced. Use authentic Chinese poster spacing, subtle alignment guides, and no modern icons except the simple scale line. The final image should feel like a premium cultural poster or PPT cover about {argument name="theme" default="the Beginning of Spring solar term"} in Chinese classical aesthetics.

Constraints: Use only the specified main title and visible Chinese labels; do not add extra large text, logos, watermark, people, buildings, or bright colors. Maintain a calm, airy, poetic mood with meticulous gongbi floral and bird details.
