Which is closer to winter, hiking or in the mountains?

In the mountains. Mountain Walking is a seven-character quatrain written by the poet Du Mu, which describes and praises the scenery of the forest in late autumn. From the sentence "Frost leaves are red in February flowers", we can see the late autumn season described in Mountain Walk, which is a poem written by the Tang Dynasty poet Wang Wei. As can be seen from the sentence "It's cold and the red leaves are sparse", this poem describes the season of late autumn and early winter, so winter refers to three months from beginning of winter to beginning of spring.
