The production and export of tea, largely paid for by imports of silver, was a fundamental feature of the prosperity of Great Qing.

The growth of opium addiction in China and importation of the drug from India turned all this around. And new forms of Christianity interacted in new ways with Chinese folk religion in the great Taiping movement.
