Because people in the Qin and Han dynasties yearned for immortality, all the images on artifacts form that era are "in fligh": immortals with feathered wings or pulled by flying horses vault through the heavens, roaming back and forth between the stars and the palace of the moon.
秦、漢兩朝企求成仙不死的心願，讓出土文物上的圖案全都「飛起來」了，仙人長出羽翼，駿馬飛騰，往來於天上星辰月宮。
