" Meanwhile, Mme Mao and her cohorts were renewing their efforts to prevent the country from working. In industry, their slogan was: "To stop production is revolution itself." In agriculture, in which they now began to meddle seriously: "We would rather have socialist weeds than capitalist crops." Acquiring foreign technology became "sniffing after foreigners' farts and calling them sweet." In education: "We want illiterate working people, not educated spiritual aristocrats." They called for schoolchildren to rebel against their teachers again; in January 1974, classroom windows, tables, and chairs in schools in Peking were smashed, as in 1966. Mme Mao claimed this was like "the revolutionary action of English workers destroying machines in the eighteenth century."
Mme Mao launched a fresh attack on foreign culture. In early 1974 there was a big media campaign denouncing the Italian director Michelangelo Antonioni for a film he had made about China, although no one in China had seen the film, and few had even heard of it or of Antonioni. This xenophobia was extended to Beethoven after a visit by the Philadelphia Orchestra. "
