The Tea Horse Road: A Thousand-Year Trade Route That Got Its Name Thirty Years Ago

Tea History & Culture｜Author：祥興茶行｜Published：2026-07-15

Caravans hauled compressed tea across 3,000 kilometers of gorges and snow passes for roughly a millennium — yet the name "Tea Horse Road" was coined by scholars in the 1990s. Here's how to tell the real history from the legends that travel with it.

Picture a mule caravan trudging through the mountain mists of northwestern Yunnan for three months, its packsaddles loaded not with silk or porcelain but with tightly compressed cakes of tea. The route it followed — winding more than 3,000 kilometers through forests, gorges, and snowbound passes — is known as the Tea Horse Road (茶馬古道) [2]. And here is a piece of trivia most people have never heard: this thousand-year-old trade route only got its name about thirty years ago.

Scholars Walked the Road Into Its Name

Nobody in imperial China ever called this route the "Tea Horse Road." The name is the work of contemporary scholars — and the naming itself makes a fine adventure story.

Naming the "Tea Horse Road": Three Milestones [1][8]

1988｜Mu Jihong (木霽弘) and Wang Ke (王可) first floated the phrase "tea-horse route" (茶馬之道) in their preface to a compilation of historical Chinese-language documents from Zhongdian (《中甸漢文歷史資料匯編》).

1990｜Mu Jihong, Chen Baoya (陳保亞), and four fellow scholars — later remembered as the "Six Gentlemen" — trekked on foot across the "Great Triangle" spanning Yunnan, Tibet, and Sichuan. The following year (1991), publishing under the pen name "Gema Mingzhu" (格瑪明珠), they used the term "Tea Horse Road" (茶馬古道) in print for the first time.

1992｜The six co-authored a book on their cultural exploration of the Yunnan–Tibet–Sichuan "Great Triangle" (《滇藏川「大三角」文化探秘》), formally defining the term — and a brand-new scholarly concept was born.

English-language scholarship independently backs this up: the term was coined collectively by Yunnan scholars in the early 1990s, and only later did it evolve from an academic concept into a resounding place-brand for southwest China's tea and tourism industries [8].

💡 Two things are worth keeping apart here: "Tea Horse Road" is a new name, but the tea-horse trade is real history. In scholarly usage, the "tea-horse trade" refers to the largely barter-based official trading system between the Central Plains dynasties and the peoples of the west, which ran for roughly a thousand years. The "Tea Horse Road" is the 1990s concept through which scholars expanded that history from scattered points into routes and networks [1]. The name is new. The road is genuinely old.

New Name, Old Road: A Millennium of Tea-Horse Markets

So what is the actual thousand-year history? The answer is the tea-horse market system (茶馬互市) — think of it as an imperial state-run barter exchange. The Central Plains had tea; the highlands had horses. Each side needed what the other could supply.

According to the traditional account presented in the Buddha Museum's "Tea Horse Road" online exhibition, one version holds that in 756 CE — the first year of the Zhide era under Emperor Suzong of Tang — horses were driven to tea markets in Uyghur territory, setting the precedent for tea-horse trading [3]. A caveat, though: Tang-era exchanges were still scattered and irregular. It was the Song dynasty that turned them into a genuine state institution. During the Xining era under Emperor Shenzong (roughly 1068–1077), the court set up a Tea Bureau in Chengdu and a Horse Purchasing Bureau in Xizhou (modern Lintao, Gansu); in 1081, the fourth year of the Yuanfeng era, the two merged into the Superintendency of Tea and Horses — the Tea-Horse Bureau (茶馬司) for short — charged solely with managing the exchange of tea for horses [6]. The system peaked under the Ming, which established twelve Tea-Horse Bureaus across the northwest and southwest; under the Qing, state operation gradually lapsed and gave way to the merchant-run "border tea trade" [6].

How the tea-horse market system evolved: scattered Tang-era trading → Song institutionalization → Ming peak → Qing shift to merchant trade [3][6]

Why did the Central Plains dynasties run this business with such seriousness? Because both sides had hard needs. The Central Plains needed the highlands' warhorses and pack animals; the highlands needed the Central Plains' tea. That exchange loop was the engine that kept the whole route turning for a thousand years.

Two Trunk Lines and a City Named for a Stove

The route ran along two main trunk lines [3]. The Yunnan–Tibet line set out from Simao (modern Pu'er) and Pu'er (modern Ning'er) in Yunnan and pushed north through Dali, Lijiang, Zhongdian (modern Shangri-La), and Deqin to reach Bangda and Chamdo in Tibet. The Sichuan–Tibet line set out from Ya'an in Sichuan and ran west through Luding, Kangding, Batang, and Chamdo to Lhasa — and could stretch onward to Kalimpong and Darjeeling in India and to Kathmandu in Nepal [2][7].

The protagonists on the road were the caravans (馬幫) — pack trains of horses, mules, and yaks, backed up by relays of human porters [3]. The yak, nicknamed the "boat of the plateau," can paw through snow to reach the withered grass beneath it, which made it the only real choice on the highest-altitude stretches [3].

The most storied town on the Sichuan–Tibet line was Kangding, known in earlier times as Dajianlu (打箭爐) — the name carries the character for "stove." In 1696 the Kangxi Emperor approved tea-horse trading there; in the Yongzheng era the court established a subprefecture at Dajianlu and garrisoned it with troops, and merchants from Sichuan, Shaanxi, and the Tibetan regions came flooding in, turning Kangding into a great frontier city built on its tea market [7]. Tea hauled in from the interior on human backs and horseback had to be transferred onto yaks at Kangding for the leg into Tibet, and the constant repacking, resting, and lodging gave rise to the town's distinctive intermediary guild-inns, the guozhuang (鍋莊) [7]. In the Qianlong era, the border-tea quota flowing from counties such as Mingshan and Ya'an to Dajianlu ran to roughly 100,000 dan — more than ten million jin [7]. One city, functioning as an entire tea transshipment hub.

Tibet's Thirst for Tea: Where History Ends and Legend Begins

A Tibetan proverb puts it plainly: "Better three days without food than a single day without tea." [3] The highland diet centers on tsampa, meat, and dairy, and the scarcity of vegetables and fruit is a matter of fact. Folk tradition holds that tea cuts through richness, aids digestion, and supplies what the diet lacks — but these health claims belong to folk experience, not to settled physiology [3].

So who carried the tea-drinking habit up to Tibet? The most widely told story goes like this: in 641, Princess Wencheng traveled to Tibet to be married, brought tea in her dowry, and Tibetan tea drinking began from there. It is a warm story — and it cannot be found in either Han or Tibetan historical records. The scholar Liu Zhiyang's textual research concludes that neither Han nor Tibetan sources offer clear evidence for it; the dowry list recorded in the Tibetan chronicle _The Clear Mirror of Royal Genealogies_ (《西藏王統記》) includes Buddhist images, scriptures, medical treatises, and musical instruments — everything, it seems, except tea [4]. Tea's real spread across the Tibetan Plateau came after the Song dynasty, on the rising tide of the tea-horse trade [4].

Claim ｜ Verdict ｜ Basis

The route has been called the "Tea Horse Road" since antiquity ｜ Misconception — scholars coined the name in the 1990s ｜ [1][8]

Tea-horse markets ran from Tang and Song times onward; the Song founded the Tea-Horse Bureau; the Ming ran twelve bureaus ｜ Historical fact (institutional history) ｜ [6]

Princess Wencheng brought tea to Tibet in 641 ｜ Legend (absent from the records; no tea on the dowry list) ｜ [4]

Tea "supplies missing vitamins and aids digestion" for highlanders ｜ Folk claim (not settled physiology) ｜ [3]

A legend is not a lie. Researchers add a reminder: the Princess Wencheng story has endured for a thousand years because she is seen as an emissary of Central Plains culture, and on the level of feeling and cultural identity the legend carries a "truth" of its own [4]. We sort history from legend not to puncture the romance, but to give each its proper place — one in the history books, one in the heart.

Why Compressed Tea?

By this point you may be wondering: why did the pack animals carry tea cakes, bricks, and tuo rather than loose leaf? The answer is pure logistics. Pressing tea shrinks its volume, toughens it against knocks, and helps it keep — exactly what you want on pack journeys that routinely ran to several months [2][7]. Kangding's routine of swapping loads onto yaks and repacking them only underlines how practical the compressed formats were on this road [7]. Pu'er tea keeps its cake, tuo, and brick shapes to this day — a standing imprint of the caravan years.

The headwaters of the story deserve a mention too. The old tea forests of Jingmai Mountain in Pu'er were cultivated by the Blang and Dai peoples following understory-cultivation practices that began in the 10th century — from a distance they read as forest; up close, they are tea gardens. In September 2023 the landscape was inscribed on the World Heritage List, becoming the world's first cultural World Heritage site with tea as its theme [5]. From the tea-ancestor beliefs of Jingmai to the butter tea on the streets of Lhasa, this road joined the tea mountains and the snow country into one continuous river of culture.

What a Cup of Tea Concludes

1. The name "Tea Horse Road" is a contemporary concept proposed by scholars in the 1990s (first used in 1991, formally defined in the 1992 book), but the tea-horse trade it carries is a genuine institutional history spanning roughly a thousand years [1][6][8].

2. Keep the institutional layers straight: scattered Tang-era trading → Song institutionalization with the Tea-Horse Bureau (1081) → the Ming peak with twelve bureaus → the Qing shift to merchant-run border tea [6].

3. "Princess Wencheng brought tea to Tibet" is a moving legend rather than documented history; Pu'er's cakes, tuo, and bricks are the caravan era's most tangible keepsakes [4][2].
