Tsinghua University (THU; simplified Chinese: 清华大学; traditional Chinese: 清華大學; pinyin: Qīnghuá Dàxué), colloquially known in Chinese as Qinghua, is a university in Beijing, China. The school is one of the nine universities of the C9 League. It was established in 1911 under the name "Tsinghua Xuetang" or "Tsinghua College" and was renamed the "Tsinghua School" one year later. The university section was founded in 1925 and the name "National Tsinghua University" was adopted in 1928. With a motto of Self-Discipline and Social Commitment, Tsinghua University describes itself as being dedicated to academic excellence, the well-being of Chinese society and to global development. Tsinghua is often ranked as the first or second best university in mainland China in many national and international rankings. Since American Secretary of State John Hay suggested that the US$ 30 million plus Boxer Rebellion indemnity money paid to the United States was excessive, in 1909, President Roosevelt then obtained congress approval to reduce the Qing Dynasty indemnity payment by US$ 10.
