The Tea Horse Road

The Tea Horse Road (Chamadao) was not a single road but a vast network of ancient trails across southwestern China. For more than a millennium, tea was carried from the tea hills of Yunnan and Sichuan westward into Tibet and Qinghai, and horses were brought back in exchange.

For Tibetans and other highland peoples, whose diets were heavy in meat and dairy, tea was essential: it cut through grease, aided digestion, and supplied vitamins. The Chinese heartland, meanwhile, desperately needed war horses. Tea and horses thus became a classic case of complementary trade — the origin of the tea-horse trade.

The interactive map below shows the three main trunk routes. Click any node to see its starting point, destination, distance, and main goods.

From Tea-Horse Trade to Tea Horse Road

Tang dynasty: the institutional beginning

Tea probably reached the Tibetan plateau early: ancient tea residues found in Ngari, western Tibet, suggest contact as early as the 3rd–4th centuries CE. But large-scale, organised tea-horse exchange is generally traced to the Tang dynasty (618–907).

In the 8th century, the Tang court and the Tibetan empire established border markets such as Chiling (present-day Riyue Mountain, Qinghai), where tea was bartered for horses. After the An Lushan Rebellion (755–763), the Tang lost the Gansu corridor to Tibet and urgently needed horses. The Tang–Tubo Ancient Road, the precursor of today’s Qinghai–Tibet route, took shape during this period.

Song dynasty: government monopoly

During the Song dynasty (960–1279), the tea-horse trade became a state monopoly. The court established the Tea and Horse Bureau (提舉茶馬司) to supervise purchase, transport, and exchange. Sichuan’s Ya’an, Hanyuan, and Leshan became the principal producers of border tea.

Official exchange rates were often unfavourable to border peoples, but private trade flourished anyway, generating a web of unofficial trails through the Hengduan Mountains.

Ming dynasty: peak and the border-tea system

The Ming dynasty (1368–1644) was the heyday of the Tea Horse Road. The court set up Tea and Horse Bureaus in Qinzhou, Taozhou, Hezhou, Xining, and Sichuan, using tea as a strategic lever to manage frontier groups while acquiring cavalry horses.

Ming border tea was highly organised: Sichuan teas were divided into “southern-route tea” (from Ya’an to Kangding) and “western-route tea” (from Guanxian to Songpan), compressed into bricks or wrapped in bamboo packs for mule transport. Kangding (formerly Dajianlu) became the largest transit hub on the Sichuan–Tibet route.

Qing dynasty to the Republic: continuation and decline

The Qing dynasty maintained Ming institutions, but private commerce grew in importance. As Yunnan tea — especially Pu’er — gained prestige, the Yunnan–Tibet route became increasingly busy from the Ming into the Qing. Lijiang and Zhongdian (now Shangri-La) became key transfer points.

In the 20th century, modern highways and railways — the Sichuan–Tibet, Yunnan–Tibet, and Qinghai–Tibet roads — replaced caravan transport, and the Tea Horse Road gradually ceased to function as a commercial artery.

Three main trunk routes

Sichuan–Tibet Route: the oldest and most influential

The Sichuan–Tibet route began in Ya’an, Sichuan, reached Kangding, then split into northern and southern branches before converging at Chamdo and continuing to Lhasa. Total length: roughly 3,100–4,000 km (1,900–2,500 mi).

• Northern branch: Kangding → Dawu → Luhuo → Ganzi → Dêgê → Jiangda → Chamdo → Lhasa
• Southern branch: Kangding → Yajiang → Litang → Batang → Markam → Zogang → Chamdo → Lhasa (roughly followed by today’s Sichuan–Tibet Highway South Line)

The 400 km stretch from Ya’an to Kangding was the hardest. Because the terrain was too rugged for pack animals, much of the cargo was carried by human porters on their backs. A local proverb describes the year-round hardship: “First and second months, snow seals the mountains; fourth, fifth, and sixth, rain soaks you through; seventh, eighth, and ninth, a little easier; tenth through winter, crawl like a dog.”

Yunnan–Tibet Route: the world of Pu’er tea

The Yunnan–Tibet route started in the Pu’er tea regions of Pu’er and Xishuangbanna, passed Dali, Lijiang, Zhongdian, and Dêqên, entered Tibet at Markam, joined the Sichuan–Tibet southern branch, and continued via Chamdo to Lhasa. Total length: about 4,000 km (2,500 mi).

This route crossed the “Three Parallel Rivers” region of the Hengduan Mountains — the Jinsha, Lancang, and Nu rivers — where gorges are deep and peaks exceed 6,500 m. A one-way journey often took half a year. During the Ming, the Mu chieftains of Lijiang expanded the Yunnan tea trade into Tibet, making Lijiang a major transit centre.

Qinghai–Tibet Route: the Tang–Tubo legacy

The Qinghai–Tibet route, also known as the Tang–Tubo Ancient Road, ran from Chang’an or Lanzhou and Xining through Yushu and Nagqu to Lhasa — more than 3,000 km (1,860 mi). Princess Wencheng travelled this road when she went to Tibet in the Tang period.

Unlike the Sichuan and Yunnan routes, which were dominated by tea, the Qinghai–Tibet route served broader political, cultural, and multi-commodity exchange between the Chinese heartland and Tibet.

Caravans, porters, and roadside settlements

The main transport unit on the Tea Horse Road was the caravan (马帮): a team of several dozen mules or horses led by a few muleteers. Caravans had strict organisation: a headman (锅头), drivers, and helpers, with fixed stops for water, firewood, and shelter.

On the Ya’an–Kangding section, where the trails were too narrow for pack animals, porters carried loads of more than 50 kg (110 lb) over mountain passes. This remains one of the most arduous labour histories along the road.

The trade also gave rise to a string of multicultural market towns — Kangding, Lijiang, Zhongdian, Chamdo, Dêgê — where Han, Tibetan, Naxi, Yi, and other peoples lived and traded together.

Modern significance: from trade route to heritage

By the mid-20th century, motor roads and railways had replaced the caravans, and the Tea Horse Road disappeared as a functioning commercial network. In the 1990s, however, Yunnan scholars Mu Jihong, Li Xu, and colleagues rediscovered and named the “Tea Horse Road” through fieldwork, transforming it from a forgotten trail into a major subject of cultural-heritage research and protection.

Today, selected sections of the road are listed as National Key Cultural Relics Protection Units. Ancient towns, post stations, ferry crossings, and cliff inscriptions along the route are actively conserved. Understanding the Tea Horse Road means understanding not only how tea reached the plateau, but also how the diverse peoples of southwestern China built long-standing economic and cultural ties.
