China's Constant Internal Migrations

From Yangtze: Nature, History, and the River, by Lyman P. Van Slyke (Stanford Alumni Assn., 1988), p. 53:

China generates paradox. The Chinese are renowned for their attachment to place, their deep identification with native soil. And yet whenever one looks at Chinese history one finds people everywhere on the move. Migration is part of this movement, the permanent transfer of people from one region to another, sometimes pushed out of their original homeland by overpopulation, poverty, disaster, or war, and sometimes attracted to new lands by real or presumed opportunities for betterment of their lives.

But migrants were not the only travelers across the Chinese landscape. Merchants big and small set forth on business trips; Buddhist monks and devout layfolk made pilgrimages or sought centers of learning; scholars aspiring to prestigious careers in the imperial civil service headed for provincial capitals or Peking to take the most fiendishly demanding examinations ever devised. Officials took up their posts across the far-flung realm, and some were exiled for real or alleged offenses to the most remote and dangerous corners of the empire; corvee labor gangs were sent to work on canals or defensive walls; boatmen and transport coolies moved the goods of the empire; one might even spot a rare travel buff exploring his world out of curiosity or scholarly interest. There were foreign traders, Japanese and Korean monks who had come to learn from Chinese Buddhist masters, ambassadors and their retinues, entertainers, bandits, fugitives. In wartime, armies were on the march. Rebel hordes, angry and desperate peasants headed by ambitious or megalomaniac leaders with their own dynastic dreams, followed the same routes as migrants, merchants, a11d scht1lars. In the mid-1960s, during the Cultural Revolution, urban youth went on an orgy of hitherto prohibited travel, sanctioned by Mao Tse-tung's revolutionary dictum to "exchange revolutionary experience"; later, beginning in 1969, some fourteen million of these urban youth were sent whether they wanted to go or not to the countryside to "learn from the peasants."
