The cowherd who walked behind shouted, only heard his voice, but didn't see him. What do you mean?

It means: it expresses the author's love for Wushan fog, and also implies his reverence for those who serve the public and work hard. The fog in Wushan is too thick, which reduces the visibility of the mountain. The old man shouting behind can only hear his voice but can't see his figure.

Said by: Wang Wei, author of Chai Lu.

There seems to be no one on the empty mountain, but I think I heard a voice. The shadow of the sunset shone into the depths of the forest, and the scenery on the moss was pleasant. Interpretation: No one can be seen in the quiet valley, only voices can be heard. The shadow of the setting sun shines into the deep forest and on the moss, and the scenery is pleasant.

This poem is about a lonely empty mountain and towering ancient forest, which is intended to create an ethereal and profound realm. The first sentence first describes the empty mountain positively, focusing on the empty mountain and cold mountain. After that, the second sentence comes out, using local and temporary "sound" to set off the whole and long-term emptiness. The third and fourth sentences describe empty mountains and then deep forests, from sound to color.
