What is "Green Mountain"?

The poem "Qingshan" describes the scenery of the autumn mountains after the rain. It does not contain much ink but is profound and meaningful. There is a tacit understanding between the scenery and the people. The author called this poem in "Yuyang Poetry Talk" It is "Those who know the taste of words while standing still for a moment should be content with them." The morning rain passes over the green mountains, and the cold smoke weaves in the desert. Moling City is missing, sitting in love with the beauty of the autumn river. Passing through the green mountains in the morning rain, the cold smoke is lightly woven in the desert. I don't see the Moling City, but I only love the color of the autumn river.
