The headquarters of the China League was moved from Tokyo, Japan to Shanghai; After the establishment of Nanjing's temporary **, it was relocated to Nanjing.

The Southern League began to divide into Sun Wen's Three People's Doctrine, and there was even more opposition to Sun's equal land, Zhang Binglin and others formed the Republican Party with Li Yuanhong, and by 1912 the China League had been divided, and only three of the nine members of the Nanjing Provisional ** were members of the China League. After 1911, the League split, and on August 7, 1912, under the organization of Song Jiaoren, the China League, the United Republican Party, the Kuomintang Party,

The Kuomintang and the Republican Association jointly established the Kuomintang in Beijing, with Sun Yat-sen as chairman and Soong Jiaoren as acting chairman. Huang Xing, Song Jiaoren, Chen Tianhua, Sun Yat-sen, Zhang Taiyan, Hu Hanmin, Wang Jingwei, Tao Chengzhang, Zhang Binglin, Cai Yuanpei, Qiu Jin and Chiang Kai-shek have been pushed onto the political stage of the people.

In December 1921, Ma Lin, a representative of the Comintern, met with Sun Yat-sen in Guilin, Guangxi, and Ma Lin proposed to Sun Yat-sen to "establish an officer school and establish a revolutionary army".

In 1924, when the Kuomintang and the Communist Party were working together for the first time and the national revolution was surging, Mr. Sun Yat-sen had great foresight and regarded "education as a sacred cause and talent as the foundation of the country", and personally founded two schools in Guangzhou, namely "National Guangdong University" (now Sun Yat-sen University) and "Chinese Kuomintang Army Military Academy" (i.e., Whampoa Military Academy). The "Chinese Kuomintang Army Military Academy" is referred to as the Huangpu Military Academy because its school site is located on Huangpu Island in the southeast of Guangzhou. The Whampoa Military Academy was established to train officers for the National Revolution, and Dr. Sun Yat-sen hoped to save China from peril by creating a revolutionary army. Sun Yat-sen delivered a speech at the opening ceremony: "When we open this school, we must use the students in it as the foundation to establish a revolutionary army, and you will be the backbone of the revolutionary army in the future." Only with the creation of the Revolutionary Army can our revolution succeed. ”

In January 1924, the First National Congress of the Chinese Kuomintang decided to establish a military academy in Huangpu, Guangzhou. Regarding the choice of principal, it was initially decided to be Cheng Qian, and Chiang Kai-shek and Li Jishen were the vice presidents. However, Chiang Kai-shek was unwilling to go to Shanghai for passive confrontation under Cheng Qian. He also sent Zhang Jingjiang to intercede with Sun Yat-sen, who appointed Chiang Kai-shek as president on May 3. In the process, Chiang Kai-shek resigned from the post of chairman of the preparatory committee of the military academy.

In addition to the well-known financial problems, the deep-seated reason for Chiang Kai-shek's resignation was his strong dissatisfaction with the current state of affairs in Guangdong, especially his failure to gain considerable status and power after the reorganization of the Kuomintang. "Chiang had ideological reservations about some fundamental issues of the revolution, such as the United Russia and the United Communist Party, and it was not appropriate to speak out openly, so he adopted a negative attitude in action." Chiang Kai-shek's resignation "was due to the dissatisfaction with the low position, and also to play with the political power trick of 'retreating into advance.'" After the establishment of the military academy, Chiang Kai-shek was the president, and Liao Zhongkai was the representative of the Kuomintang. Subsequently, Li Jishen and Deng Yanda were appointed as the directors and deputy directors of the coaching department, and Wang Bailing and Ye Jianying were the directors and deputy directors of the professor department; Dai Jitao (later Zhou Enlai) and Zhou Enlai were the principal and deputy directors of the Political Department, and He Yingqin was the chief instructor. In addition, there are Xiong Xiong, Yun Daiying, Xiao Chunu, Nie Rongzhen, Zhang Qiuren and other communists as instructors and responsible for all aspects of work.

In May 1924, 350 students were officially admitted from 1,200 candidates, and 120 were reserved. Enrollment starts on May 5. On 16 June, the opening ceremony of the Army Military Academy was held, and Sun Yat-sen went to the venue to make an enthusiastic speech to the young people: "From today onwards, we must make a will, and for the rest of our lives, we will not have the mentality of being promoted to an official position and making a fortune, but only know how to do the cause of saving the country and the people." Sun Yat-sen also announced the precept: "Three People's Doctrine, the sect of our party, to build the Republic of China, to enter Datong, to consult Erduoshi, to be the vanguard of the people, to be slack, to be obedient, to be diligent and courageous, to be faithful and loyal, to be dedicated to one heart and one morality, and to carry out the whole thing", this precept later became the Kuomintang party song and the official school song, and was composed by Chen Zukang, and the school song has been sung since the fifth phase of Whampoa.

On January 25, 1925, the Whampoa Military Academy established the "Young Military Society", with Liao Zhongkai as the president, and on February 1, the first issue of the society's publication "Young Soldiers" was published. The Whampoa Military Academy initially had many instructors from the Soviet Union, but Chiang Chung-zheng's relations with the Chinese Communist Party broke down during the warlord war, so these Soviet instructors left.
