It was already noon when the scorching sun was high up in the sky and the sun's rays were as hot as fire. Looking from afar, heat waves were rolling on the dry ground surface and the sand on the ground was extremely dry as if they had been stir fried in a wok, radiating with heat and thus causing the air to move. Within a radius of ten li, it was practically impossible to see anything green except for a short thorny bush and the trunks of some toppled poplar tree that had been air-dried, reflecting the harsh natural environment. Occasional strong winds would blow across the sand on the ground, conjuring it up like a yellow dragon and causing pain once it came into contact with one's face.
