The dew is white in autumn, the leaves are whistling, and a sad cry passes through the sky. The west wind blows up the yellow dust in the sky. Two rows of weeping willows beside the official road outside the suburbs of Daming Mansion in southern Hebei. There is no more green pedestrians than that day. The dripping smoke drips green. The bald strips sway in the wind and add a bit of bleak atmosphere. At dawn, a group of escort agencies appeared on the road, as if they were very happy and rushed to the night. They did not look sharp last night, and they laughed loudly.
