Xiutu
Xiutu (Chinese: 休屠王; pinyin: Xiūtú Wáng, also rendered as Hsiu-tu, lit. "The king who puts an end to massacres") was a king in the Hexi corridor of the Gansu region, west of Wuwei, during the 2nd century BCE. "Xiutu" (休屠) is also an early Chinese transliteration for the name of the Buddha. According to the Shiji and the Book of Han, King Xiutu, together with King Hunye, was a vassal of the Xiongnu under their ruler Yizhixie (伊稚邪 126–114 BCE),  and was antagonistic with the Han dynasty. King Xiutu, considered as "Hu" (胡, barbarian) by the Han, was positioned between the Xiongnu tribes of the Mongolian steppes to the north, the Han to the east, the Saka to the northwest, the Tocharians to the west, and the Southern Qiang (南羌, Nanqiang) to the south.
