How did Chinese commmunist increase their power during world war 2?

Answer 1

The Chinese Civil War was a civil war fought between the Kuomintang (KMT) and the Chinese Communist Party (CCP) that left an estimated million or more people dead. The war technically began in the April of 1927, amidst the Northern Expedition, in which the KMT emerged victorious in a war against the warlord-backed Beijing government and established a new regime in Nanjing. However, people often regard the final three years of the war as the true highlight of long civil war that set the stage for the eventual communist victory for a number of reasons: the political and military incompetence of the KMT to decisively resist Japanese occupation drew heavy criticism; the inflation and corruption that plagued the years of the war likewise lead to the disenchantment of the Chinese people; and finally, the war itself gave invaluable time for the CCP to establish the political and military strength that would prove decisive in the civil war. Indeed, it would be difficult to disagree that the Sino-Japanese war of 1937-1945 was a key factor that prepared and conditioned the final three year culmination of the KMT-CCP conflict that helped lead to the communist victory.
