Expelling Tatars means expelling northern minorities, such as Manchu. Tartu is a disparaging term used by Han people in history to refer to Mongolian, Manchu and other ethnic minorities in northern China.

The expulsion of Tatars was one of the plans decided by 1905 after the establishment of China-EU in August. In June of that year, Sun Yat-sen changed his slogan to "nationalism". 1906 10, Sun Yat-sen, Huang Xing and Zhang Taiyan formulated the declaration of the military government and once again put forward the slogan of "expelling the Tatars".

The correlation is as follows

1905, Sun Yat-sen and Huang Xing established the China League in Tokyo, Japan, with the 16-character platform of "expelling the Tatars, restoring China, establishing the Republic of China, and sharing land equally". Sun Yat-sen interpreted the political program of the League as the three principles of "nationality", "civil rights" and "people's livelihood" (referred to as the Three People's Principles for short), and the newspaper of the League was People's Daily. "Tatar" refers to the Qing government and Manchu rulers and nobles.

This is the first national bourgeois revolutionary party in China. Sun Yat-sen is the Prime Minister and Huang Xing is the Deputy Prime Minister. The Chinese League is consistent with the government organization of the Republic of China envisaged by Sun Yat-sen: there are three departments, namely, the executive, the legislature and the judiciary, which is actually the principle of separation of powers.
