From the Tang Dynasty Wang Wei's "Mountain", the original text:
The stream of the river has been flowing for less than a day, and white stones are exposed on the riverbed. The weather is getting colder and the red leaves on the branches are becoming scarce.
There is no rain on the winding mountain road, the smoke is misty in the dense pine trees, and the water vapor is heavy, as if to flow, and then the clothes of passers-by.
Translation:
The west of Beijing gurgled and flowed through the white stone exposed by phosphorus, and the weather became cold and the red leaves became thinner.
It didn't rain on the mountain road, but the green mountain color was so thick that it seemed to wet people's clothes.
This little poem describes the scenery in the mountains in early winter with what the poet saw and felt when he walked in the mountains. "It didn't rain on the mountain road and the clothes were wet." Mainly write the whole picture of the mountains in early winter. It should have been a bleak and lonely winter, but the whole Qinling Mountain is still green and lush, and the mountain road runs through the boundless thick green. Castle peak color itself is ethereal and bright, unlike tangible things that can be touched, so it is called "empty green".
