At the beginning of the preface, three metaphors are used to write catkins: "Like a flower in the fog" describes the misty; "Like snow before the wind", it is elegant and rolling; Rain Like Yu Yun is gentle and distant. If "like snow before the wind" is a bit too similar to the previous semantics, then the other two metaphors are completely the poet's unique imagination and creative description. Of course, many people describe chemicals as "flowers in the fog", but it is very rare to compare them with Yang Shuhua. As for the metaphor of "Rain Yu Yun" to Huayang, it is indeed the first one, and it is very appropriate and beautiful. After using three metaphors to describe the appearance of Huayang, the poet used "ruthlessness" and "sentimentality" to describe its expression: Huayang has no roots or ties and floats in the wind. It seems that it is really a heartless thing, not attached to anyone, not attached to anyone; However, it seems very affectionate and meaningful. It landed on the duckweed, making the water look fresh and lovely green. When it meets its lover, it will also give birth to life! (Press: Huayang is white fluff brought by willow seeds, so it is also called willow cotton. In ancient times when science was underdeveloped, it was thought that poplars could grow duckweeds when they fell into the water. This is naturally a misunderstanding, but it is a beautiful imagination. )
Xia Kun also described the fate of catkin poplars from another angle: the traces of poplars can be seen everywhere in West Lake, Nanmo and Dongcheng. The creator seems to have assigned it a full-time task: to see it off every year. It was sent away by a messenger and will disappear without a trace. It seems to have been abandoned by the wind, and it seems to have been abandoned all day-it is like a fickle wanderer and an unlucky beauty.
