Only this sentence, without context, is hard to say. Looking at the meaning of the sentence alone, it can be understood that the west wind is the autumn wind, which means leaning against the railing and looking up at the distance. Before autumn, standing on a high place overlooking the railing, the west wind is blowing, and I am infinitely disappointed (Note: Why are you disappointed? One is to look at people from afar, and the other is that geese fly south, which is also the artistic conception of people, but this sentence did not mention the geese, just guessing)
Unintentional estimation of every sentence means that every sentence in Goose's letter has not been sincerely missed or knocked on the heart of the leaner, making people feel strange, cold, desolate and helpless.
