The Monguor (; Tu: Mongghul), the Tu people (), the White Mongol or the Tsagaan Mongol, are Mongolic people and one of the 56 officially recognized ethnic groups in China. The "Tu" ethnic category was created in the 1950s. According to the 2000 census, the total population was 241,198, who mostly lived in the Qinghai and the Gansu provinces. The 2010 census gave their number as 289,565. The Monguor people speak the Monguor language, which belongs to the family of Mongolic languages but has been heavily influenced by both the local Chinese and Tibetan dialects. Today, nearly all Tu people also speak Chinese. Most are farmers and some keep livestock. Their culture and the social organizations have been influenced by Tibetan Buddhism, Confucianism, Taoism and local beliefs. A few Tu in Huzhu and Minhe are Christian, the result of on-going American and Korean missionary work in the area. Ethnic origins The ethnic history of the Monguor is contested. It has been variously suggested that their origins are related to the Tuyuhun Xianbei, to Mongol troops who came to the current Qinghai-Gansu area during the time of the Mongol conquests, to the Shatuo and/or to the Han Chinese. Terminology Origins Some references argue that the Chinese term "Tu" was derived from the name of Tuyühu Khan, who was the older son of the King of Murong Xianbei who migrated westward from the northeast in 284. The last character of Tuyühu, pronounced as "hun" today, may have been pronounced "hu" in some dialect of ancient Chinese language. The contemporary reference of this name is rendered "Tuyuhun" in China and the West should be "Tuyühu." It came from the Chinese phonetic transcription of his original name "Teihu", which is still a common name seen among the Monguor today. Since the Chinese language cannot represent "Tei," two characters of "Tu" and "yü" were used. The ethnonym "Tu" in Chinese came from the abbreviation of "the Tuyühu people" or "the people of the Tuyühu Empire." Between the years 908 and 1042, the reference became simplified into "Tuhu" and "Tüihu" people. As the other ethnic groups of the Tuyühu Empire came to be ascribed with different ethnonyms through subsequent history, the Xianbei who founded the empire remained to bear with the identity of "Tu." The name "Tu" was most likely associated with a derogatory meaning and "indigenous people". Its derogatory undertone came from the concurrent meaning
