520 __ |a Taking this as a starting point, tracing the past and present of this city through time, the unique cultural characteristics and 8,000 of Chinese civilization history are contained in the tens of thousands of words: the sound of camel bells, the Western Journey of the Marquis of Bao Wang through this place; silk from Chang'an floating all the way through this place; the luxurious chariots of Emperor Yang of the Sui Dynasty specially going to this place, the worlds first World Expo stopping here; the monks going west and east chanting lotus flowers step by step in their lingering; the iron hooves of Genghis Khan's war trampled the hundred-year dream of the Western Xia; the fief of the Prince of Suo in the horn of the Ulaq welcomed a new nation later called You; the willows planted by Zuo Gong and the dead but unrotten poplars grew together; the star of the dawn shone on the cap badge of the Route Army... This city is full of fragrance in the dust of history.
