Why It's Fun to Explore

Have you ever wondered while reading Chinese history or classical poetry:

"Where exactly on today's map are Jiankang (the Six Dynasties capital), Huangzhou (where Su Dongpo composed the Red Cliffs Rhapsody in exile), Languan Pass in the Qinling Mountains (where Han Yu halted his horse in the snow), or Zhuxianzhen (Yue Fei's northern campaign frontier)?"
"How many names did Chang'an hold across two millennia, and what pivotal events unfolded on that soil?"
"How did the realm evolve step by step—from the Partition of Jin and the Seven Warring States at the opening of Sima Guang's Zizhi Tongjian (403 BCE), Qin's unification campaigns, Emperor Wu of Han opening the Hexi Corridor, High Tang's Four Garrisons of Anxi, and Yuan's Xuanzhengyuan jurisdiction over Tibet, to Zeng Jize's recovery of Ili (1881 CE) and the 20th-century shift from the 'Begonia Leaf' (秋海棠) map to the 'Rooster' (雄鸡) map?"

Chronicles of the Realm (jiangshan-map) brings together 2,400+ years of Chinese history across 18 historical periods into a single interactive parchment atlas—featuring multi-stage territorial and prefecture snapshots, ancient cities, strategic mountain passes, poetic and battlefield landmarks, chronological milestones, and reigning monarchs & imperial eras. No heavy print atlases required—just drag the timeline and click any city to travel through space and time.

Feature 1: Scrub the Timeline to Watch Realms Rise & Fall, Track Monarchs, and Compare Ancient & Modern Borders

Multi-Polity Confrontations on a Single Canvas: From the Seven Warring States (Qin, Chu, Qi, Yan, Zhao, Wei, Han) alongside Zhou, Yue, Ba-Shu, Zhongshan, and Yiqu, to the Three Kingdoms warlords (Yuan Shao, Cao Cao, Liu Bei, Sun Quan, Gongsun's Liaodong), Northern & Southern Dynasties, Five Dynasties & Ten Kingdoms, and Song, Liao, Western Xia, Dali, Jin, and the Mongols—all rendered side-by-side in high-contrast traditional parchment hues. Hover over any polity in the bottom-left legend to highlight its territory, or click to zoom straight to it.
Multi-Stage Territorial Evolution & Dashed "Ghost Boundary Diffs": At every major territorial milestone—such as Qin's conquest of Ba-Shu (316 BCE), Yan General Qin Kai's expansion into Liaodong (300 BCE), Ma Yuan's bronze pillars in Jiaozhi (43 CE), Sima Yi's campaign in Liaodong (238 CE), Li Jing's conquest of Tuyuhun (635 CE), the Four Garrisons of Anxi & Wang Xuance's campaign in Central India (648 CE), Yuan's Xuanzhengyuan rule over Tibet (1288 CE), Ming's Hami & Seven Guards West of Jiayuguan (1404 CE), the 1881 Treaty of Saint Petersburg recovering Ili, the 1898 foreign leased territories, the 1945 retrocession of Taiwan, and the 1946 transition from the "Begonia Leaf" (秋海棠) map to the "Rooster" (雄鸡) map—click any milestone or phase dot to switch maps and reveal the previous phase's dashed vermilion Ghost Boundary Diff so territorial gains and losses are immediately visible.
Inline Reigning Monarch & Imperial Era Display: The timeline dynamically displays the reigning monarch (temple/posthumous title + personal name + reign span, e.g., Emperor Wu of Han · Liu Che, Emperor Taizong of Tang · Li Shimin, Emperor Shengzu of Qing · Xuanye) alongside the exact imperial era year.
Ancient Prefecture Hover Inspection & Modern X-Ray Lens: First-level administrative divisions (Commanderies, Circuits, Routes, and Provinces) are rendered with deduplicated Parchment Casing borders. Zoom in and hover over any prefecture (e.g., Ming Yingtian Prefecture or Three Kingdoms Jingzhou) to inspect its jurisdiction and modern provincial equivalents, or toggle the X-Ray Lens to project modern provincial boundaries directly over the historical map.
Dynamic River Courses, Ancient Lakes & Grand Engineering Works: As you scrub through time, historical shifts of the Yellow River, expanding and shrinking ancient lakes (Yunmeng Marsh, Lop Nur / Puchanghai), Warring States/Qin/Han/Ming Great Walls, Sui-Tang & Grand Canals, the Silk Road, and Zheng He's maritime routes evolve in lockstep with each era.

Feature 2: Click Any Ancient City or Strategic Pass to Uncover 2,400 Years of History (`Trace Place`)

Click any ancient city or mountain pass on the map (or double-click anywhere on the canvas) to open its Trace Place genealogy card:

Bilingual City Lore Banner & 2,400-Year Administrative Genealogy: At the top of the card, read a curated poetic epigraph and historical biography for the city; below, trace how its name and administrative jurisdiction evolved across all 18 historical eras—from Warring States and Qin commanderies, Han regional inspectorates, Tang circuits, and Song routes to Yuan/Ming/Qing provinces and modern municipalities—complete with Imperial Capital badges and dynastic seat remarks.
Site-Specific Landmark Events: Beneath each dynasty row, inspect major historical events that took place right on that spot (e.g., Shang Yang's Reforms and Qin's Unification at Xianyang, Guan Yu Flooding the Seven Armies at Fancheng, the Xuanwu Gate Incident at Chang'an, or Yue Fei's Martyrdom at Lin'an). Click the Key Events pill in the top-right of the card to filter for dynasties with major events, and click any event to time-travel straight to that year!
Strategic Mountain Passes & Poetic / Battlefield Landmarks: Explore famous mountain passes—including Hangu Pass, Tongguan, Jianmen Pass, Yanmen Pass, Yumen Pass, Yangguan, and Shanhai Pass—rendered with traditional Hanque gatehouse icons and strategic terrain notes, alongside famous battlefields and literary landmarks such as Red Cliffs (Chibi), Gaixia, Wuzhang Plains, Orchid Pavilion (Lanting), Yueyang Tower, Pavilion of Prince Teng, Languan Pass, Loulan, Lop Nur, and Issyk-Kul.

Feature 3: Person Chronicles — Trace Any Historical Figure Across Time & Space

Click the top-left Universal Search Box (with a rotatable e.g. figure preview and quick-search chips, or type any monarch, general, statesman, monk, or poet such as Cao Cao, Huo Qubing, Sima Qian, Yue Fei, or Zheng He) to open Person Chronicle (点人溯事), plotting every milestone of their life with delicate cartographic hairline arcs and directional ticks across changing dynastic borders:

Qin Shi Huang's Unification Campaigns (238–221 BCE): From suppressing the rebellion at Xianyang and Wang Jian's attack on Ye, to the fall of Han, Zhao, Yan, Wei, Chu, and Dai, culminating in the surrender of Qi at Linzi—as you advance stop by stop, watch the six rival kingdoms merge into the Qin Empire right on the map!
Zhang Qian's Mission to the Western Regions (138–126 BCE): Depart Chang'an, endure over a decade of Xiongnu captivity without surrendering the Han imperial staff, and blaze the trail to Dayuan (Fergana), Kangju, and the Greater Yuezhi.
Zhuge Liang's Emergence & Northern Expeditions (207–234 CE): From the Three Visits at Longzhong and the alliance at Chaisang before Red Cliffs, to entering Shu, the White Emperor City entrustment, the Southern Campaign across the Lu River, Hanzhong's Memorial on Deploying the Troops, Mount Qi, and the autumn winds of Wuzhang Plains.
Xuanzang's Pilgrimage to India (627–645 CE): Slip past Yumen Pass alone across the Moheyan Desert, scale the icy Bedel Pass, cross the Indus, and study at Nalanda Monastery before returning to Chang'an.
Li Bai's Grand Travels Across Tang China (701–762 CE): From Suyab and boyhood in Shu, sailing out through the Three Gorges at twenty-four, scattering gold in Yangzhou, serving in the Hanlin Academy at Chang'an, meeting Du Fu in Luoyang, receiving amnesty at White Emperor City, to his final years at Dangtu.
Su Shi's Literary Exile Across Song China (1056–1101 CE): From leaving Meishan for the capital Kaifeng and gazing at the moon in Mizhou, to composing the Red Cliffs Rhapsody in Huangzhou exile, Huizhou, and crossing the sea to Danzhou on Hainan Island.
Wang Yangming's Unity of Knowledge & Action (1472–1529 CE): From birth in Yuyao and imprisonment in Beijing, to his enlightenment at Longchang in Guizhou, pacifying bandits in Southern Ganzhou, capturing the rebel Prince of Ning in 35 days, teaching at the Tianquan Bridge in Shaoxing, and his final words "This mind is bright and clear; what more is there to say?" at Nan'an.

Each time you step to the next event (‹ / ›, ← / →, or Space to auto-play), the timeline year, reigning monarch, imperial era, and dynastic territories evolve in sync with their footsteps, highlighting the active transition arc alongside bilingual primary-source excerpts and poems written at that exact site.

AI Agent & LLM Integration

Chronicles of the Realm works out of the box as a historical-geography visualization engine for LLMs and AI Agents. Models never need to guess latitude/longitude coordinates—simply extract two semantic parameters from a poem or historical text, year and place, and the atlas automatically resolves ancient/modern place names, centers the camera, renders dynastic borders and multi-stop trajectories, and opens the Trace Place genealogy card:

Machine-Readable Specification: llms.txt

Ready-to-Use Agent Skill: skills/jiangshan-atlas/SKILL.md (includes the zero-dependency CLI renderer skills/jiangshan-atlas/scripts/jiangshan.py)
