The Tea Horse Road — 茶馬古道, Chama Gudao — was not a road in any modern sense. It was a network of mountain paths connecting the tea mountains of Yunnan and Sichuan to the high plateaus of Tibet and Central Asia, active from at least the Tang Dynasty (7th century) through to the 20th. For over a thousand years, compressed Pu'er cakes traveled one way, warhorses the other.
The trade was not incidental. Chinese dynasties could not field cavalry without Tibetan horses. Tibetan communities could not survive high-altitude winters without the nutrients in aged tea. What moved along this road wasn't a luxury — it was infrastructure. The Tea Horse Road built monasteries, cities, and cultures on both ends. Pu'er tea was compressed into cakes specifically because of this journey — dense enough to survive months on a yak's back at 4,000 metres.
Most of the road has been absorbed by paved highways. What remains — the stone-paved sections in Yiwu and Shaxi, the ancient trading posts, the farmers still pressing cakes by hand — is what we are going to see.
This year is the Year of the Horse.
We thought about that when we planned the route.
