"Tàijí arises from Wújí (Non-Extreme); it is the mother of Yīn and Yáng."
四兩撥千斤 — "Four ounces deflects a thousand catties."
— Wáng Zōngyuè 王宗岳, Tàijí Quán Lùn 太極拳論, c. 18th century
What "Supreme Ultimate" Means
The name Tài Jí Quán (太極拳) is drawn from one of the most ancient and fundamental concepts in Chinese cosmological thought. Tài (太) means "supreme" or "ultimate" — the greatest possible extent; Jí (極) means "extreme" or "pole" — the absolute limit. Together, Tàijí (太極) denotes the Supreme Extreme, the state of dynamic balance from which all phenomena arise. Quán (拳) means "fist" or "boxing." The name therefore describes not a style named for its founder or region, but one named for a cosmological principle — the art that embodies the universe's fundamental dynamic.
This name was not always used. The art was originally called Shísān Shì (十三勢 — Thirteen Postures/Powers), and the transition to the name Tàijí Quán is attributed to the treatise Tàijí Quán Lùn (太極拳論 — Discourse on the Supreme Ultimate Fist), attributed to Wáng Zōngyuè (王宗岳), a Shanxi scholar-martial artist of the Qing Dynasty Qianlong period (c. 18th century). His essay — considered the supreme theoretical text of the art, revered by all schools regardless of lineage — grounds the art's practice explicitly in Daoist cosmology: "Tàijí arises from Wújí (無極 — Non-Extreme); it is the mother of Yīn and Yáng. When in motion, they separate; when still, they unite."
In the practice of Tàijí Quán, every movement contains both yin and yang simultaneously — neither can exist in isolation. Every extension contains a withdrawal; every advance contains a retreat; every hardness conceals softness; every apparent softness conceals the capacity for explosive release. The practitioner's task is not to choose between yin and yang but to maintain their dynamic balance at all times — the stillness within movement, the movement within stillness, the jìng zhōng chù dòng, dòng yóu jìng (靜中觸動，動猶靜 — "within stillness touching movement, movement yet stillness").
The Thirteen Postures & Wáng Zōngyuè's Treatise
The art's foundational technical framework is the Shísān Shì (十三勢 — Thirteen Powers), which organizes the art's entire technical vocabulary through the lenses of the Eight Trigrams (bāguà 八卦) and Five Elements (wǔ xíng 五行). The eight hand/body methods correspond to the eight trigrams; the five footwork directions correspond to the five elements. Together they constitute the complete grammar of Tàijí combat.
The Tàijí Quán Lùn contains what all subsequent Tàijí traditions recognize as the art's supreme theoretical statement. Its key contribution is identifying the path of progress: from technique-familiarity (zhuó shú 著熟) to understanding integrated power (dǒng jìn 懂勁) to arriving at spiritual clarity (shén míng 神明). The treatise famously states: "察四兩撥千斤之句，顯非力勝" — "observe the phrase 'four ounces deflects a thousand catties' — clearly this is not victory through strength." This single principle — that the art operates through alignment, timing, and sensitivity rather than muscular force — defines everything about how Tàijí Quán is practiced and why it takes the form it does.
How Tàijí Quán Moves
楊式 Yáng Shì & 陳式 Chén Shì
Within the Wu Tan system as transmitted through Liú Yúnqiāo and Dài Shìzhé, two great Tàijí Quán traditions are practiced: the Yang-style (Yáng Shì 楊式), tracing to the foundational Yáng family lineage; and the Chen-style (Chén Shì 陳式), tracing to the art's earliest known source in Chénjiāgōu Village. Each carries a distinct character and training methodology, and together they give the practitioner access to Tàijí's full technical and theoretical range.
The Yang style, founded by Yáng Lùchán (楊露禪, 1799–1872), who traveled to Chénjiāgōu and studied under Chén Chánxìng, is the most widely practiced Tàijí Quán in the world. The Yang family refined the art across three generations — Yáng Lùchán, his son Yáng Bānhòu (楊班侯), and grandson Yáng Chéngfǔ (楊澄甫, 1883–1936) — who created the definitive large-frame Yang standard form. Its characteristics are large, open, expansive postures; smooth, even-paced, flowing movement; equal emphasis on health cultivation and martial application.
The 32-Posture Form (三十二式, sānshí'èr shì) is a condensed, accessible introduction to Yang-style structure — covering the fundamental postures in a compact, learnable sequence. The 108-Posture Form (一百零八式, yībǎi línɡ bā shì) — also known as the traditional long form — is the comprehensive Yang-style canon: it is the art's full vocabulary, repeated across three sections at different body-side combinations, developing complete structural conditioning and technical mastery. The 108 form is considered the foundation of genuine Yang-style attainment: without it, the art's deeper power cannot be fully developed.
Chen style is the oldest and most complex form of Tàijí Quán, originating in Chénjiāgōu Village, Wen County, Henan Province. Unlike the smooth, even-paced Yang style, Chen style is characterized by alternating slow and fast movements, explosive releasing of force (fā jìn 發勁), stomping footwork (zhèn jiǎo 震腳), jumping and leaping techniques, and the distinctive spiral silk-reeling force (chán sī jìn 纏絲勁). It is simultaneously demanding physically and internally nuanced.
The Wu Tan system's Chen style is transmitted through the lineage of Dù Yùzé (杜毓澤, 1897–1990) — the foremost Chen-style custodian in Taiwan — and his disciple Xú Jì (徐紀, Adam Hsu) and Dài Shìzhé 戴士哲, senior Wu Tan disciple of Liú Yúnqiāo. Dù Yùzé received the Old Frame (Lǎo Jià 老架) directly from Chén Yánxī (陳延熙) — great-grandson of Chén Chánxìng — and the New Frame / Húléi Frame (Hūléi Jià 忽雷架) from Chén Míngbiāo. His three-stage curriculum — Old Frame → New Frame → Cannon Fist (Pào Chuí 炮捶) — represents one of the most complete and historically authentic Chen transmissions preserved in Taiwan.
The Wu Tan curriculum include both Yang-style and Chen-style Tàijí Quán, taught by Liú Yúnqiāo's senior disciples including Xú Jì and Dài Shìzhé. This dual exposure — the smooth large-frame Yang style as structural foundation and health cultivation, and the explosive spiral-force Chen style as deeper martial development — reflects Liú Yúnqiāo's philosophy of teaching complete, multi-dimensional martial education rather than any single narrow system.
The Teachers & the Transmission
Later, through Chén Míngbiāo — Chén Yánxī's nephew — Dù received the New Frame / Húléi Frame (Hūléi Jià 忽雷架, also called "Second Set Small Frame" 二套小架), a dynamic and flowing variant deriving from the Zhàobǎo tradition; and the Cannon Fist (Pào Chuí 炮捶), the explosive second routine of the Chen system. Dù's complete three-stage curriculum represents a rare convergence of multiple Chen transmission streams preserved unchanged in Taiwan. A Taiwanese scholar-practitioner website notes: "This Old Frame, originating from Chén Yánxī, has an ancient and upright structure quite different from the commonly circulated versions today — a very special transmission." After retiring from military engineering (he held the rank of senior engineer at the Military Ordnance Department), Dù devoted his later years entirely to transmission. His disciple Xú Jì (徐紀 — Adam Hsu) — primary Wu Tan disciple of Liú Yúnqiāo — received this complete Chen transmission and transmitted it within the Wu Tan system.
The Wu Tan Taiwan curriculum lists Liú Yúnqiāo's senior disciples as teaching Tàijí Quán alongside the primary Baji-Pigua curriculum. Xú Jì is listed as teaching "Cháng Quán, Tàijí Quán, Bāguà Zhǎng, Bājí Quán, Pīguà Zhǎng" — Tàijí Quán second in his list, reflecting its importance within Wu Tan's complete curriculum. The Wu Tan philosophy of multi-dimensional martial education — which Liú consistently embodied — treated Tàijí's internal cultivation as essential complement to the explosive power development of Baji and Pigua: the yin to their yang.
