The Macartney mission
In 1793 Britain sent Macartney at the head of a seven-hundred-strong mission, bearing a model steam engine, an orrery, repeating pistols, and warship models, seeking trade and a resident envoy. The Qing court fixed on the "kowtow ritual" and stored the exhibits as tribute in the Yuanmingyuan warehouses. Qianlong’s edict to the British king ran: "The Celestial Empire abounds in all products and lacks for nothing, and has never needed the goods of outer barbarians to trade for what it lacks." Macartney wrote another verdict in his diary: the Qing was "a dilapidated first-rate man-of-war." Forty-seven years later, the guns of the Opium War confirmed the latter verdict.
The Four Treasuries and the literary inquisition
Qianlong gathered the realm’s books to compile the Complete Library of the Four Treasuries, taking in over three thousand four hundred titles — while wholly destroying or partly destroying over three thousand more, and altering beyond count: words such as "hu," "lu," and "yidi" (barbarian) were systematically expunged. Compiling books and destroying books were two faces of one project. During his reign there were over a hundred and thirty cases of literary inquisition, and a single line — "the clear wind cannot read, why does it riffle the pages?" — could bring a family’s extermination (the case’s authenticity is disputed, given as legend). The master catalogue of knowledge was compiled, and the living water of thought drained dry.
