Although
tea is, for Tibetans, indispensable, Tibetan-inhabited areas
produce almost no tea at all and it had to be imported from
other parts of China. This is why, for instance, Tibetan horses
were used to trade for tea produced in China's hinterland
in ancient times.
In the 4th century, troops of the Tubo Kingdom captured some
prefectures of China's hinterland. They found tea but had
no idea how to use these "dried tree leaves." Gradually,
however, they learned to make and drink tea. They even added
butter to tea.
During
the late Tang Dynasty (618-907) in China's hinterland, the
Tang and the Tubo maintained good ties. Tang silk fabrics
and tea were used to barter for Tubo horses and cows. During
the ensuing Five Dynasties, in the Song and Jin periods, the
bulk of Hexi areas were seized by Tubo troops. Tubo horses
were then traded for Han tea. In 1372, the Ming (1368-1644)
court set up the Tea-Horse Office to cope with the growing
need of the Tibetans for Han tea.
In the 60s, tea bushes
were successfully planted in south Tibet.
