Mao might have his criticisms of useless scholarship and writing, but he also has some suggestions as to how one might write:

Articles should store up forces within. Emerging from Longmen, the Yellow River rushes all the way down to Tongguan. As it turns eastwards, it again rushes to Tongwa. Again it turns northeastwards and rushes to the sea. Once it comes out of hiding and changes its course, it goes for a thousand li without stopping. This is called a big turn. So it is with composition. (The Writings of Mao Zedong, vol. 1, p. 18)

To compose (zuo wen) well, we need to be skilfull, hence the use of the word ‘do’ (zuo); to write (xie), we need to wield the brush furiously, hence the use of the word ‘sketch’ (xie). (p. 19)
