Supporting this position, Mao was elected to the Party Committee, taking up residence in Shanghai. At the First KMT Congress, held in Guangzhou in early 1924, Mao was elected an alternate member of the KMT Central Executive Committee, and put forward four resolutions to decentralise power to urban and rural bureaus. His enthusiastic support for the KMT earned him the suspicion of Li Li-san, his Hunan comrade. In late 1924, Mao returned to Shaoshan, perhaps to recuperate from an illness. He found that the peasantry were increasingly restless and some had seized land from wealthy landowners to found communes. This convinced him of the revolutionary potential of the peasantry, an idea advocated by the KMT leftists but not the Communists. He returned to Guangzhou to run the 6th term of the KMT's Peasant Movement Training Institute from May to September 1926. The Peasant Movement Training Institute under Mao trained cadre and prepared them for militant activity, taking them through military training exercises and getting them to study basic left-wing texts. In the winter of 1925, Mao fled to Guangzhou after his revolutionary activities attracted the attention of Zhao's regional authorities. When party leader Sun Yat-sen died in May 1925, he was succeeded by Chiang Kai-shek, who moved to marginalise the left-KMT and the Communists. Mao nevertheless supported Chiang's National Revolutionary Army, who embarked on the Northern Expedition attack in 1926 on warlords. In the wake of this expedition, peasants rose up, appropriating the land of the wealthy landowners, who were in many cases killed. Such uprisings angered senior KMT figures, who were themselves landowners, emphasizing the growing class and ideological divide within the revolutionary movement. In March 1927, Mao appeared at the Third Plenum of the KMT Central Executive Committee in Wuhan, which sought to strip General Chiang of his power by appointing Wang Jingwei leader. There, Mao played an active role in the discussions regarding the peasant issue, defending a set of "Regulations for the Repression of Local Bullies and Bad Gentry", which advocated the death penalty or life imprisonment for anyone found guilty of counter-revolutionary activity, arguing that in a revolutionary situation, "peaceful methods cannot suffice". In April 1927, Mao was appointed to the KMT's five-member Central Land Committee, urging peasants to refuse to pay rent. Mao led another group to put together a "Draft Resolution on the Land Question", which called for the confiscation of land belonging to "local bullies and bad gentry, corrupt officials, militarists and all counter-revolutionary elements in the villages".
