Communist--both a Marxist and a Leninist.
Filled the leadership vacuum when Chaing Kaishek failed.
During wartime, three magical weapons were the United Front (gave troops to Nationalists, secretely remained in local governments even with the three-thirds system), party-building (Indoctrination program stressing enlarging membership, reformulating party doctrine, improving training, growing challenges), and armed struggle (guerilla fighting the Japanese, building strength for after the war).
Gained following from peasants, working class, and those who wanted to get rid of Japan.
Sinification of Marxism--didn't want reliance on 8-legged essay.
Nationalist blockade and Japanese pressure forced Communists to be self-sufficient and eveyone complied willingly.
Listening to complaints of the peasants was essential--sent intellectuals and party cadres to villages.
Named chairmen in March 1943.
