在毛乌素大沙漠的南缘,陕北靖边县北端无定河上游支流红柳河北岸,曾经依天耸立过一座赫赫有名的古城遗址。它,就是五胡十六国时期匈奴贵族赫连勃勃在鄂尔多斯高原建立的大夏国的京都——统万城。沧海桑田,斗转星移。千百年来,这座中国历史上最完整、最雄伟、最坚固的少数民族都 At the southern edge of the Maowusu desert, the northern part of the Wuding River, north of the Jingbian County in northern Shaanxi, runs along the northern bank of the northern riverside of the willow, and once stood by the ancient ruins of a famous city.

For thousands of years, this is the most complete, majestic, and strongest minority in Chinese history.
