He's Liu Yong and Li Shangyin's Liu discuss the differences between Liu and Liu from the characteristics of images and the emotions contained in images.

In Li Shangyin's "Singing Willow", the characteristics of the image are: the first two sentences are about the prosperity of spring, and the last two sentences are about the depression of autumn. Between ups and downs, time flies and life is in a hurry. Emotion placed with heart: every sentence is written about willow, but there is no word "willow" in the whole article. Every sentence is a scene, every sentence is a thing, and every sentence is a person, expressing the lament for the sparse and withered autumn willow. The objective contrast is ruthless, but people's sensitivity to phenology and life changes is full of emotion. In the contrast between nature and life, appreciating the value and significance of life process makes the works have unique philosophical significance. This is the common feature of Yishan's poems.

The first three sentences of He's "Chanting Willow" are all about willow, and the three poems are divided into different parts of willow, and each sentence has its own characteristics. The last two sentences are questions and answers. The willow tree skillfully transitions to the spring breeze, saying that the spring breeze cuts off these delicate willow leaves, thus praising spring. The emotion attached to the intention of "singing willow" is singing green willow, but it is actually singing spring breeze.
