Obviously, literature is a question of quality rather than quantity. In a speech given on 19 June 1961, which was only published in the Literary Gazette (Wenyi bao) in February 1979 as the cultural testament of the late premier, Zhou Enlai drew a crude parallel between literary and industrial outputs: “Certain laws governing material production also hold good for mental production. When pressed too far mental production will suffer, perhaps even more seriously. Quotas and pressures of time are vexing problems for mental workers. Take the writing of poetry as an example. Among our leading cadres, Comrade Chen Yi likes to write poems. He composes very quickly and is a prolific writer. He is a genius in this respect. But, it is different with Chairman Mao. He writes only after much deliberation. Though he writes less, he writes with such magnificence and vitality and produces extremely concentrated poems. We should not demand a poem a day from Chairman Mao, nor should we interfere with Comrade Chen Yi and ask him to write less. Mental work cannot be uniform.”
