The central content of the declaration of the League is the four programmatic slogans of "expelling Manchu, restoring China, establishing the Republic of China, and averaging land rights", which can be said to be the early form of the Three People's Principles before the Revolution of 1911. The first two were nationalism, the third was civil rights and the last was people's livelihood. The name of the Republic of China was also determined when the League was founded. At the first National Congress of the Chinese Nationalist Party in June 5438 +0924+10, Sun Yat-sen pointed out: "Re-study the current situation of the country and reinterpret the Three People's Principles." From June 65438 to August of the same year, he gave 16 speeches, expounding the Three People's Principles, which was the most systematic and detailed chapter of Sun Yat-sen's Three People's Principles.
