Li returned to
Guangdong in 1921 at the invitation of Guangdong Army chief of staff
Deng Keng (邓铿). Deng was assassinated in March 1922, and
Chen Jiongming staged a coup in June of that year, which Li helped to put down. For this, he received command of the army's 1st Division. ''.|200px in the founding ceremony of the People's Republic of China on October 1, 1949.|200px in September 1949. Left to right:

Whampoa Military Academy under Chiang Kai-shek. After
Sun Yat-sen's death in March 1925, the Guangdong government was reorganized as the National Government, and Li was appointed commander of the 4th Army, which had formerly been the Guangdong Army. He spent the next year destroying Chen Jiongming's remaining power. When the
Northern Expedition began in July 1926, Li's 4th Army joined the push northward. During this time, Li also served as Governor of Guangdong, military affairs commissioner, and acting president of the Whampoa Military Academy. In 1927, he was elected to the Central Executive Committee of the
Kuomintang and helped Chiang in the
purge and massacre of Communists. In November 1927, Li left Guangdong with
Wang Jingwei to attend a plenary session of the Committee in
Shanghai on the subject of restoring party unity. In his absence,
Zhang Fakui staged a coup. However, officers loyal to Li successfully put down the coup, forcing Zhang to surrender, and Li returned to Guangdong on 4 January 1928. On 7 February 1928, Li was made a member of the standing committee of the
Military Affairs Commission. He was also made commander in chief of the newly established
Eighth Route Army. On 1 March, Li became chairman of the Guangdong branch of the Political Council of the Kuomintang, and on 30 March he was made chief of the general staff of the Northern Expedition. During the remainder of the year, Li attended meetings in Beijing, and briefly served as acting commander in chief of the Nationalist forces when Chiang Kai-shek left Beijing for
Nanjing. He was appointed to the State Council on 8 October and resigned as Governor of Guangdong in November.
Fujian People's Government In 1929, Li traveled to Nanjing to attend the 3rd National Congress and mediate a dispute that had arisen between the Nationalist government and the
New Guangxi clique. However, talks broke down in March, the members of the clique were expelled from the Kuomintang, and Li was placed in detention. He was not freed until after the Japanese attack on
Mukden in 1931. In 1933, Li joined forces with
Chen Mingshu to launch a successful military revolt in
Fujian, and after the initial seizure of power, became Chairman of the
Fujian People's Government. However, in 1934, the revolt was crushed by Chiang Kai-shek, and Li was forced to flee to
Hong Kong in January 1934.
Second Sino–Japanese War In 1935, Li joined with associates to found the Chinese People's Revolutionary League, which advocated resistance against Japan and overthrow of the Nationalist government. In 1936, Li participated in a joint
Guangdong-
Guangxi revolt against the government, but after it collapsed, Li returned to Hong Kong. The order for his arrest was rescinded by Chiang. In 1938, in the name of unity against the Japanese threat, Li was restored to membership in the Kuomintang, and again became a member of the
Military Affairs Commission and the State Council. During the Sino-Japanese War, Li served in several military posts. In 1944, he was appointed president of the Military Advisory Council, and worked to consolidate resistance against Japan in southern Guangxi. At the 6th National Congress of the Kuomintang in May 1945, Li was elected to the Central Supervisory Committee of the Kuomintang, and served as a delegate to the National Assembly the following year.
Expulsion from Kuomintang and Revolutionary Committee On 8 March 1947, Li issued a statement calling for reconciliation between the Kuomintang and the
Chinese Communist Party. For this, Li was again expelled from the Kuomintang on Chiang's orders, for "making unwarranted statements and inciting the people to riot". Li began working to unite current and former Kuomintang members who opposed Chiang Kai-shek. This led to the formation of the
Revolutionary Committee of the Kuomintang in 1948, with Li as its first chairman. ==People's Republic of China==
