Using rhetoric skillfully, the context of "there seems to be no one on the empty mountain, but I think I heard a voice" is written, changing the scenery, and an original ecological picture comes into view, expressing the poet's detached and peaceful mind.
Walking in the mountains, in the quiet autumn mountain, I can't see houses and smoke, and I doubt whether this mountain is inhabited. I can't help asking myself, "Where are they?" I was meditating when I suddenly heard a cock crow in the white clouds in the mountains. Oh, the original home is still at the top of that high mountain. This last sentence, "Smell a chicken outside the cloud", is natural and does give people the feeling of "a thousand words can't be said".
