I want to know the answer to the following question:
What group organised guerrilla warfare against the Japanese in China?
All the background I'm provided with is that "In August of 1940, Chinese communists launched an offensive in Central China; in retaliation, Japan instituted the "Three Alls Policy" ("Kill all, Burn all, Loot all") in occupied areas to reduce human and material resources for the communists.". Is that enough to answer the question?
