For the split within the League of Left Wing Writers, the best work in English is Hunter, »Chinese League of Left Wing Writers; see also Spence, Gate of Heavenly Peace, chapter 9; and for a highly partisan view, Chung Wen, »National Defense Literature,« Chinese Literature, no. 10 (1971): 91—99. In Chinese the materials are fragmentary but numerous; for recent comments see Xinwenxue shiliao, no. 2 (1979): 243-58.
