Why CCP won the Chinese Civil War?

Ever since 1934, two main political parties in China, Communist Party of China and Nationalists, were in a constant struggle for power. This animosity led to the Chinese Civil War, which started after the defeat of Japan in 1945 and lasted until 1949. Throughout those years GMD gradually lost its support and in the end CCP won.
Although the surrender of Japan meant a great victory for China, the situation had not developed as expected for the head of GMD, Chiang Kaishek. First of all, the war ended too early. Had the Japanese resisted longer, Chiang believed that the Americans would set up their air bases and armies in China and as a result they would defeat not only the Japanese but also overwhelm the Communist party. However, the Americans chose the Pacific Islands instead of China and Chiang´s plans fell apart. Another problem was the Russian occupation of Manchuria after their declaration of war on Japan, issued after the bombing on Hiroshima and Nagasaki on August 9. Furthermore, CCP resistance disabled GMD to claim the liberated areas. All of these factors undermined the power of GMD and contributed to the rise CCP.
Although CCP was much weaker when it came to military power, their strategy, morale and public support was considerably higher than those in GMD. Chiang´s incapability to destroy CCP when they were considerably weakened in 1945 proved fatal in the following years, when their popularity and numbers rose. During the war against the Japanese, GMD did not participate as much as CCP. Chiang´s expectations were that the Communist and Japanese would destroy each other. However the only outcome of this policy was that CCP, not GMD, was viewed as the protector of China against Japanese.
Furthermore, in areas that they owned, Communists introduced various reforms, which included confiscating land from landlords and giving it to peasants. Instead of the GMD who focused only on the needs of rich urban classes, CCP showed a real interest in the welfare of common people. In fact, Mao´s party was much closer to fulfilling the 3 Principles of People (to make China a free, prosperous and powerful nation) than GMD had ever been. It is said, that CCP won the war already in 1945 in the hearts of the people. Moreover, Chiang had to face crisis even within the party, which split into several rival factions and faced increasing number of desertions which included also high-ranked officials. This showed that even the members themselves did not believe their leaders and went over to the CCP.
The last of the major factors of GMD´s defeat was economy. The war against Japan was a huge financial drain, which Chiang wanted to solve by printing more money. However, the result of this action was inflation, the value of money rapidly dropped and even more Chinese were put into poverty.
GMD had simply too many failures – inflation, failure to defeat the Japanese as well as CCP, loss of support from the Americans and inability to gain the support of peasants. The latter is from the most part the result of. On the other hand, CCP provided effective administration and political structure in the countryside. I believe that the main reason for the Mao´s victory in 1949 was his ability to win the hearts of the people and gain their support.
