The Red Letter康熙的红票
In the autumn of 1716 the Kangxi Emperor had a public letter printed on vermilion paper — in Chinese, Manchu, and Latin — and handed to European ships at Canton to carry home. It searched for the envoys he had sent to Europe and never heard from again. Those envoys were Jesuit missionaries. The emperor called them his own 钦差 — imperial commissioners.
Eighteen copies of the Red Letter survive in the world's great libraries. Not one is in China. The Qing's own official histories never mention it.

The artifact
Roughly 39 cm wide and 93 cm long, the Red Letter is not a brush-written edict but a printed broadsheet — issued as an open letter by Kangxi's Imperial Household Department, stamped with the seal of the Governor of Guangdong, and left deliberately unsealed so that any Westerner might carry a copy away. The West came to call it the “Red Manifesto.”
巡抚
院印
武英殿等处监修书官伊都立、王道化、赵昌等，字寄与自西洋来的众人。我等谨遵旨于康熙四十五年已曾差西洋人龙安国、薄贤士，四十七年差西洋人艾若瑟、陆若瑟，奉旨往西洋去了。至今数年，不但没有信来，所以难辨真假。又有乱来之信，因此与鄂罗斯的人又带信去，想是到去了。必竟我等差去人回时，事情都明白之后，方可信得。若是我等差去之人不回，无真凭据，虽有什么书信，总信不得。因此，唯恐书信不通，写此字，兼上西洋字刊刻，用广东巡抚院印，书不封缄，凡来的众西洋人，多发与带去。康熙五十五年九月十七日。
The tone is plainly factual: Kangxi states that he sent two parties of envoys west, that none has returned with formal word, and that until they do he will trust no message. The phrase “when the whole matter is made clear” (事情明白之后) was, for two centuries, a riddle — because no Qing record explains what matter, or why an emperor wrote to Europe at all.
All four were Jesuit missionaries serving in China. Two crossed the Pacific via the Americas; two took the Indian Ocean route. Most died on the way. When the letter reached Europe, only Provana still lived — and he died on the voyage home. The Latin text names them simply as men sent by the emperor, with no title; but Provana's tombstone in Canton read “Tomb of the Imperial Commissioner, Lord Ai.”
Pacific / Americas route — perished in a storm sailing from Brazil to Europe.
Pacific / Americas route — perished with de Barros at sea.
Indian Ocean route — reached Europe, received by the King of Portugal; died on the return voyage. Buried with imperial honors at Canton.
Indian Ocean route — reached Europe and died there soon after.
How a forgotten broadsheet came back
Three drafts in the Hall of Diligence
Sorting palace materials after the dynasty's fall, the great Qing historian Chen Yuan found three Kangxi manuscripts in the Maoqin Hall beside the Qianqing Palace — among them a draft, in the emperor's own corrected hand, of the Red Letter's Chinese text. With no record in the Qing histories to guide him, Chen still pieced together, from a dozen related manuscripts and Western church sources, the outline of a fifteen-year correspondence between Kangxi and Rome.
Rolled up in an Oxford stack
David Helliwell, who ran the Chinese section of Oxford's Bodleian Library, saw a Red Letter in the 1970s — rolled and tied to a board, with only a shelf-number; no one knew what it was. He opened it, found nothing to go on, and put it back exactly as it lay.
Eighteen copies, scattered across the world
A 1992 Paris exhibition let Helliwell place his Oxford scroll; on its back, a faint pencil note — “EDouce” — revealed it had been given by the collector Francis Douce and had lain unidentified for a century. He published the story online and messages came in from everywhere. Eighteen copies are now known — in Munich, Wolfenbüttel, Berlin, Oxford, London, Cambridge, Paris, Leiden, the Vatican, Stockholm, Boston, Indiana, Cornell, Tokyo, St. Petersburg, Glasgow. None in China.
¥1.61 million at auction
At a Beijing spring sale a Red Letter appeared as “The Kangxi Emperor's Edict to the Multitude of the West” — the first to surface in the Chinese-speaking world. Estimated at ¥700,000–800,000, it climbed to ¥1.61 million. Decades of scholarship had finally made its place in history legible.

The puzzle at the center
Read the letter and the questions follow at once. Why would the emperor of the Qing send Westerners as his envoys — and send two parties of them? Why would he trust foreign priests with his most sensitive business of state?
Most missionaries held no official rank, yet they came and went in the Forbidden City and attended the emperor in the inner court — a privilege that made ranking ministers envious. How?
When the Qing negotiated its border with Russia, the actual negotiators of the 1689 Treaty of Nerchinsk were two Jesuits, speaking Latin, defending Qing interests more fiercely than the Manchus themselves.
On Provana's tomb the emperor wrote 钦差 — imperial commissioner. What relationship lets a Chinese emperor make a European priest his commissioner abroad?
Earlier scholars answered: Kangxi kept the missionaries close because he was curious about Western science and they were useful to him. Sun Litian argues this reverses cause and effect.
The argument
Four reversals run through the book — each turning a familiar story inside out.
Trust came before interest
To be near an emperor for years, the precondition has always been trust, not usefulness. Interest is born of contact. Kangxi could not have wanted Western learning out of thin air. The order runs: he trusted the missionaries first; that trust brought contact; contact let them teach him; only then did he find Western knowledge interesting and grasp its uses.
They entered as bondservants, not officials
The door into the inner court was not the bureaucracy but the household. The first missionaries arrived as war captives — bondservants (奴才 / 包衣) attached to the Tong (佟) clan, Kangxi's maternal family, and later to the Imperial Household Department. In Manchu society a bondservant's standing was set not by the lowly word but by whose household he served. To be the emperor's man was an enviable place to stand.
There was no clash of civilizations
The conflict that mattered was internal to Catholicism — the Chinese Rites Controversy — not between China and the West. The missionaries themselves, who had lived across many cultures, found China unusually open; their worry was that the Chinese learned Western science too fast. Christianity entered the inland “market” of belief easily, where it could not enter Tibet's. To read this history as a culture-clash is to project a later defeat backward.
History turned on contingency, not law
The enterprise did not have to end. It ended because Kangxi died suddenly in 1722 and Yongzheng's contested succession led him to ban Christianity — court politics, not cultural destiny. With the personal channel cut, China missed the decisive eighteenth century of the scientific revolution, just as algebra and calculus were arriving. A defense of the individual and the accidental against the seductions of “big history.”
The conventional account reads this chain backwards, beginning with the emperor's “interest.” The book restores the order.
Three parts, seven chapters
Westerners enter the Qing circle of power
How war captives became the emperor's household men — through cannon, through the Tong clan, through a calendar feud, and through a treaty with Russia.
Captured in the Ming–Qing wars, the Jesuits Buglio and Magalhães passed as bondservants from prince Hooge to Tong Tulai — head of the clan that produced Kangxi's mother. The thread that bound the Manchus to Westerners was the cannon: the Portuguese “red-coat” artillery that had killed Nurhaci's hopes was exactly what the Tong-led Chinese Banners were built to master. Priests, gunfounders, and the Han Banners rose together.
In Manchu eyes a bondservant's rank came from his master — to belong to the emperor's household was an asset, not a stigma.
Adam Schall, already an official in Beijing, dared not shelter the two captive priests — the law on harboring runaways was severe.
Adam Schall ran the Astronomical Bureau until the anti-Christian official Yang Guangxian brought the “Calendar Case” (历狱) — a prosecution entangled with fortune-telling and Manchu–Han factional lines. Schall was condemned; the cause survived. Sun reads the episode not as proof of Chinese hostility to science but as a contest over who would hold a technical office at court.
Yang Guangxian, a marginal figure in his own day, became a star only to later theorists who needed an anti-Christian voice.
Calendars and eclipse prediction were sovereign technologies — to mis-predict the heavens was to lose the Mandate's instrument.
After the boy emperor seized the regent Oboi in 1669, Ferdinand Verbiest rose to indispensability — casting cannon, building astronomical instruments, and opening the world to Kangxi. In 1689 the Jesuits Pereira and Gerbillon negotiated the Treaty of Nerchinsk for the Qing in Latin. The treaty was signed in Latin, Manchu, and Russian — with no Chinese. Peter the Great, furious that Jesuits had served “heretics,” banned the order from Russia.
Verbiest's traction designs and a steam-carriage sketch sat beside Newton's 1688 steam-carriage idea — the same questions, two ends of Eurasia.
The Russians were astonished: the priests defended the Qing more stubbornly than Manchu envoys had.
In 1692, after the treaty, an Edict of Toleration legalized Christianity — engineered quietly by the powerful minister Songgotu. The missionaries were not ministers but household men of the 内务府, the emperor's private apparatus. From inside it they introduced China to Europe and Europe to China — a two-way exchange, with Kangxi having Western books translated into Manchu for his banner youth.
To be of the Household meant access to the emperor's person — and printed permits (印票) bearing the Household's seal.
Kangxi adjudicated a brawl among Westerners by personal edict — the act of a head of household, not a court of law.
The Red Letter and Sino-Western exchange
A pope's decree, a legate's defiance, a system of permits, and an emperor who waited fourteen years for an answer from Europe.
In 1704 Pope Clement XI forbade Catholic converts to take part in Chinese rites — ancestor tablets, incense, homage to Confucius. When the legate Tournon arrived, Kangxi received him not as a state embassy but as family — a relative of his household men, handled entirely by the Imperial Household. To test Rome's grounds he examined Bishop Maigrot in person. Then he created the permit (领票) system: missionaries who would stay in China for life received a ticket; and he sent his own commissioners west.
Kangxi first assumed the legate had come to settle a quarrel between the French and Portuguese Jesuits — “a hard thing, to judge a family's affairs.”
The permit declared the holder a Westerner who “would never return to the West” and had been received in audience — a household credential, not an office.
When the legate Tournon publicly forbade missionaries to take Kangxi's permit, the emperor's patience held for fourteen years. He printed the Red Letter — his open letter to Europe — and sent word even via the Russians. A second papal legation came; Peter the Great's embassy came. Kangxi waited for the one answer that would tell him whether his envoys lived, and whether Rome had heard him.
Provana's tombstone likened him to the Han envoy Su Wu — thirteen years detained abroad, faithful in returning to report.
The emperor's open letter, unsealed and freely given, was a sovereign reaching past the Church to Europe at large.
Silence after the glory
Not a culture closing its doors, but a succession closing a channel: why Yongzheng banned the faith.
Kangxi died suddenly in 1722; the contested accession of his fourth son brought a new household and new men. Within a year Yongzheng — a serious Buddhist layman, forty-five and fully formed, whom the missionaries had never cultivated — expelled them from the Imperial Household and then banned Christianity. Sun ties the ban to the succession struggle: the missionaries had bet on the deposed heir-apparent and on other princes, and were left on the losing side. Stripped of Household status, they were reduced to fortune-tellers with telescopes.
On the Buddha's birthday in 1727, Yongzheng praised Buddhism and dismissed the very idea of a “Lord of Heaven” before his assembled court.
Even after the ban, no missionary blamed a clash of cultures — they waited, as Verbiest's generation had, for the next turn of court favor. It never came: Europe dissolved the Jesuits in 1773.

The conflict that was real — and where it lay
For more than a century, Catholics disagreed over a single question: were the Chinese rites — ancestor tablets, incense, homage to Confucius — religious idolatry, or civil custom a convert could keep? This was the Chinese Rites Controversy. Crucially, it was an argument inside the Church, not between China and the West.
Compatible — civil custom
Much of the Jesuit mission, with Kangxi's endorsement- Honoring Confucius expresses reverence for a teacher, not worship of a god.
- Ancestor tablets and incense are acts of remembrance (慎终追远), in harmony with Catholic piety.
- Rome itself respected Confucius; the rites need not be forbidden.
Incompatible — idolatry
The Dominicans and some Jesuits; affirmed by the Pope- Many who venerate Confucius also pray to him for success — that is worship of another.
- Whether ancestor rites contain petitions for protection is impossible to settle.
- A baptized convert must hold one God only — and pray to no other.
Clement XI forbade the rites in 1704; Kangxi, finding a foreigner presuming to judge Chinese custom, made it his own affair. The standoff hardened — but over a Church's internal definitions, not an incompatibility of civilizations. As Kangxi's correspondents put it, even in Europe the Church held Confucius in full respect.
The emperor reads algebra
One Kangxi edict is endlessly quoted to prove he obstructed Western science: he calls the new algebra “mediocre” and “laughable.” Read whole, it shows the opposite — a sixty-eight-year-old emperor studying a brand-new subject daily with his sons, and ordering the missionaries to translate it properly.
朕自起身以来，每日同阿哥等察阿尔巴拉新法，最难明白。他说比旧法易，看来比旧法愈难……尔将此上谕抄出并此书发到京里去，着西洋人共同细察，将不通的文章一概删去。
“Since I set out I have, each day, examined with the princes the new method of Algebra — most hard to understand. They say it is easier than the old method; it looks harder… Copy out this edict and send the book to the capital; have the Westerners examine it together and strike out whatever does not read clearly.”
- 01
“Al-bara” is Algebra — from Al-Khwārizmī, the 9th-century Arab founder. To Kangxi's missionaries it was a new subject too; Foucquet, teaching it, replaced letters with the cyclical characters.
- 02
Newton (1643–1727) and Kangxi (1654–1722) were contemporaries. Kangxi's reign sat on the very eve of the scientific revolution, just as algebra and calculus became its decisive tools.
- 03
What Kangxi could not yet see — what Europe also took a century to digest — was why one computes with letters at all. His complaint was the same as Europe's.
- 04
He coined the Chinese terms for “unknown” (元), “degree” (次), and “root” (根) — and asked, near the end of his life, for any new method of extracting roots.
Anyone reading this source without a thesis to defend, the book says, would marvel at how hard the old emperor worked at his mathematics.
Against “big history”
The afterword is the book's quiet manifesto. Histories of the mission, Sun observes, almost all begin from the known ending — the enterprise's brilliance under Kangxi and its later collapse — and then comb the past for whatever proves a chosen theory. The earliest answer was Chinese xenophobia; its successor, since the 1980s, was the clash of cultures, most famously Jacques Gernet's China and the Christian Impact.
The theories run backward
Both xenophobia and culture-clash presuppose that Christianity was banned because of a cultural problem, then mine the record for conflict. They are interested only in friction — which is why a marginal figure like Yang Guangxian becomes a star, while figures of synthesis vanish.
The vanished figures of synthesis
Xue Fengzuo brought logarithms to river-control; Ming Antu proved the Catalan numbers a century early. They are barely named in modern histories of the period — for the simple reason that there was no clash in them, only convergence.
Two acts of judgment
History should be judged at least twice: by what its participants felt at the time, and by later context. The second must not erase the first. Yang Guangxian's writings drew no echo in his own day — that is the historical fact; their later revival belongs to another history, a matter of “reception.”
The individual and the accident
The hunt for laws of history, inherited from 18th–19th-century thinkers who envied physics, drives historians toward abstract “big history” and away from living individuals and their contingencies. Trigault's suicide, Kangxi's chill caught hunting, a pandemic in 2020 — the accidental shapes the record. There may be no law to summarize at all.
“Perhaps all the historian need do is dig out the stories and the details that actually happened.”
