title: The Long Saber (單刀法選) — Cheng Zongyou, 1621
---
The **Selected Methods of the Single Saber** (單刀法選, *Dāndāo Fǎxuǎn*), printed by **Cheng Zongyou** in **1621**, is the companion to his famous staff manual — and one of the most fascinating documents in Chinese martial history, because it records a current flowing the "wrong" way. At the height of the sixteenth-century **wokou** (倭寇) pirate wars, when Japanese-style swordsmen were cutting through Chinese troops on the coast, Cheng went and *learned the enemy's sword* — the two-handed long blade — and set it down in verse and illustration. His manual naturalized a Japanese weapon into the Chinese arsenal, and three centuries later it became the textual root of the living art now called the **miaodao** (苗刀).
This page is a companion to the staff manual from the same collection:
## A Japanese sword, made Chinese
The blade Cheng describes is not the ordinary Chinese military saber. It is the long, two-handed sword — the kind the Japanese called the *ōdachi/nodachi* — that **wokou** raiders wielded with such effect that, as Cheng admits, longer Chinese weapons "are again and again defeated by it." Its very name records the novelty: 單刀, "**single** saber," because — unlike the ordinary *dao* used in a pair or with a shield — this blade was so large it took **both hands**, leaving no hand for anything else.
Cheng did not invent the response; he documented one strand of it. He sought out a **Zhejiang master named Liu Yunfeng** (劉雲峰), who, he says, possessed "the true transmission" of the Japanese method. Because Liu's techniques "had postures and methods but no names," Cheng — exactly as he had done for the staff — **drew each posture and gave it a name**, so students could remember them. The manual opens with a prose essay, the *Discourse on the Single Saber* (單刀說), whose first lines state the case plainly:
> 器名單刀，以雙手用一刀也。其技擅自倭奴……其用法，左右跳躍，奇詐詭秘，人莫能測，故長技每每常敗於刀。余故訪求其法，有浙師劉雲峯者，得倭之真傳，不吝授余，頗盡壺奧。
> *The weapon is named the "single saber" because one wields a single blade with both hands. Its technique comes from the Japanese … In use it leaps to left and right — strange, deceptive, unfathomable — so that long-reach weapons are again and again beaten by the saber. I therefore sought out its method; there was a Zhejiang teacher, ****Liu Yunfeng****, who held the true Japanese transmission and, without reserve, taught it to me, fully to its depths.* — opening of the *Discourse on the Single Saber*, 1621 woodblock
(The word Cheng uses for "the Japanese," 倭奴, was the era's hostile term for the coastal raiders — literally "the *Wo* slaves." His admiration for their *sword*, in the middle of a war against them, is exactly what makes the manual remarkable.)
Cheng was not alone. A generation earlier the great general **Qi Jiguang** (戚繼光) had captured a Japanese fencing text — the *Kage-ryū catalogue* (影流之目錄) — from the pirates and worked out his own two-handed method, the **辛酉刀法** of 1561. Both Qi's and Cheng's saber methods were soon absorbed into Mao Yuanyi's vast military encyclopedia, the **武備志** (*Treatise on Military Preparedness*, 1621). The long saber was, briefly, a current event in Chinese arms.
## The book
*Selected Methods of the Single Saber* is a single compact volume built like the staff manual — verse, picture, and application together:
- the prose **Discourse** (單刀說) quoted above, on the weapon's origin and virtues;
- a sequence of combat **applications against the spear** — the long-reach weapon the saber was meant to defeat;
- the **twenty-two posture-figures** of the saber (單刀勢圖), each a named stance with its illustration, followed by **twelve further continuation figures** (續刀勢) — thirty-four plates in all;
- and a **solo routine** (a "connected sequence," *tao*) with a **movement diagram**, exactly the device Cheng used to map the staff form.
It was issued in **1621** as one of the four parts of Cheng's collected martial works, **《耕餘剩技》 ("Skills Beyond Farming")** — alongside the staff manual, the spear, and the crossbow. A Republican-era reprint repackaged the set as the **《國術四書》 ("Four Books of National Arts")**, and it became a touchstone of the early twentieth-century martial-revival presses.
## The honest history: a method that lapsed, then was revived
It would be tidy to draw an unbroken line from Cheng's 1621 saber to the saber arts of today. The record does not allow it. As the historian **Ben Judkins** notes, the actual practice of the two-handed *dandao* "appears to have died out quickly." Qi Jiguang himself had shown that the surest way to beat a Japanese swordsman was **better drill and pole-arms**, not a duel of blades — and once the pirate threat receded, the specialized long saber fell out of use. The renewed interest in it during the **Qing and the Republic** is, in Judkins's careful phrase, best understood as a series of **revival movements** reaching *back* to the Ming texts, not a living tradition handed *forward* from them.
That is the right frame for what came next.
## From 單刀 to 苗刀 — the birth of the miaodao
The modern **miaodao (苗刀)** is the living descendant of the Ming two-handed saber — but it is a twentieth-century **revival**, and even its name is modern. We keep the romance and the record side by side, as everywhere on this wiki.
The weapon most people now meet as the heir of Cheng's saber is the **miaodao** (苗刀): a slender, single-edged blade well over a metre long, gripped in both hands. The name is often mistaken for something ancient or ethnic. It is neither. **苗 means "sprout" or "seedling"** — the blade is named for its long, narrow shape, "like a young shoot of wheat" (如麥苗). (Older Chinese texts do mention a *different* "苗刀" carried by **Miao** peoples; that homonym is an unrelated weapon, and conflating the two is a common error.)
The name in its modern martial sense was coined only in **1921**, when the warlord **Cao Kun** (曹錕) raised a martial-arts battalion at **Cangzhou** in Hebei and hired the saber masters **Liu Yuchun** (劉玉春) and **Ren Xiangrong** (任向榮) to teach the two-handed blade. The unit became known as the "**miaodao battalion**" (苗刀營) — and the weapon had its modern name. Liu's outstanding student **Guo Changsheng** (郭長生), nicknamed "the Swallow" (燕子) for his speed, carried the art to the **Central Guoshu Institute** in Nanjing, where around **1927** he and **Ma Yingtu** (馬英圖) codified the standard miaodao forms (taught in various lineages as the "two roads" or "four roads," 二路 / 四路), fusing the saber with the **piguazhang / tongbei** methods of the Cangzhou school. Nearly every miaodao practiced today descends from that Cangzhou revival.
So the lineage is real but *layered*: a Japanese sword art, naturalized by Ming soldiers and recorded by Qi Jiguang and Cheng Zongyou, preserved on paper in the **武備志**, and then **reconstructed and renamed** in the Republican era. Cheng's 1621 manual is the indispensable *document* in that chain — not an unbroken master-to-student line, but the text that made the revival possible.
## The companion volumes
The saber was one quarter of Cheng's *Skills Beyond Farming*. The others:
- **長槍法選 ("Selected Spear Methods")** — the spear, which Cheng learned from **Li Kefu** (李克復) of Henan; the spear was widely reckoned the "king of weapons," and Cheng's treatment sits in the lineage of the famous Yang-family spear tradition.
- **蹶張心法 ("Heart Method of the Foot-Drawn Crossbow")** — a rare manual on the heavy **foot-spanned crossbow** (蹶張弩), spanned by bracing the bow with the feet; one of the few martial-crossbow texts to survive.
- Cheng later added a treatise on **archery** (射史, c. 1629), notable for being among the first to *illustrate* shooting technique in detail.
Together they make Cheng Zongyou the most thoroughly **documented weapons master of the late Ming** — the man who, more than any other, put Shaolin-era martial practice into print.
## Reading the original
The 1621 text and its woodblock plates are **public domain**. The cleanest freely available scan is the **1842 (Daoguang 22) Juwen Hall reprint** of *Skills Beyond Farming* on **shuge.org** (書格) — which contains the saber, spear, and crossbow (the staff volume is absent there; for the staff, see its own page). The searchable text of both *Skills Beyond Farming* and the *Treatise on Military Preparedness* (which reproduces the saber method) is at the **Chinese Text Project**.
