What does snow tell us? Snow is the most suitable book for us to read in Weeds. The author gives a detailed and vivid description of the snow scene in the south of the Yangtze River and the snow scene in the north, and shows his own tendency in comparison. The author appreciates Snow in the North more, because Snow in the North, Never Touch, Fly, Spin and Rise embody an independent and flamboyant personality and spirit. This spirit is also the author's consistent motivation. When flying, the snow in the north seems a little lonely, but it is this loneliness that highlights the value of self-persistence, which is also the difference between Lu Xun and ordinary writers: he is willing to be misunderstood, determined to die and live, and "saved from hopelessness."
