The congratulatory poem only describes the spring willow, which is an image and a feature. Its characteristics are dignified and pure, as beautiful as jade. The emotion it reposes is that the beauty of willow lies in the spring breeze of skillful hands, and the beauty of willow image is used to set off the skillful hands of spring breeze, just as the beauty of horse is used to praise Bole. The topic of emotion is "praise".

Shi Li wrote the spring willow first, and then the autumn willow. There are two images and two characteristics, which are manifested as the beauty of the spring willow and the depression of the autumn willow. In contrast, he emotionally pinned it on the image of "willow", which has changed greatly since ancient times, to express people's life in youth and frustration in old age. The topic of emotion is "sadness".
