Appreciation of Poetry What is the role of Miracle, the swordsman, in poetry?

The poet put the swordsman in the background of such whistling west wind and heavy snow, which effectively set off the swordsman's heroic temperament. The snow is boundless, the world is boundless, there is a person in it, holding the sword independently, looking forward to the road ahead ... what kind of image and tolerance should it be! Even better, the author asked the swordsman, "Where can I repay you?" This means that it is difficult to identify the road in such a big snowstorm. Where can I seek revenge for my benefactor and avenge him in return for his kindness in meeting you? On the surface, this is a word that the swordsman can't say, but it praises his firm belief that he is determined, not to be hindered by snow and snow, and to work hard to achieve his goal.
