The title of this poem is Joy, but it is actually about melancholy and depression. Poets are in the dark ages, always unhappy and unhappy. The mysticism of western literature at the end of the century that he came into contact with also branded him with pessimism and suspicion. This "happiness" is a portrayal of his thoughts and emotions at that time.
The poem repeatedly recites "What color is joy", "What sound is joy" and "How does joy come from", and uses synaesthesia to capture the visible, audible or sensible images such as pigeon wings, swallow's red mouth, reed flute, running water, warm hands and like eyes, and weaves colorful images to set off a happy situation. But it is not expressed in affirmative sentences, but a series of question marks gush out. Its artistic effect is to outline a lot of happiness that we can't reach, and its profound meaning can be interpreted as: happiness may be all this, but it is not all this, and happiness is in the air. Based on this, the poet finally expressed his feelings in the first three sections: "For joy, my heart is the eyes of the blind,/but is it cute, like my melancholy?" This last paragraph is obviously an emotional reversal. Careful readers can see that this inverted emotion is what the poet really wants to express, but in artistic expression, the poet stops at this emotion that should be emphasized, thus leaving an open artistic space for readers to fill, which is the ingenuity in the artistic framework.
Another artistic feature of this poem is that it pays great attention to the coordination of colors, just as the poet confessed: "I am not looking for its shape from the cooling of a concept, but some colors and patterns emerge in my mind." (Road in a Dream) "Pigeon's wings" match "Swallow's red mouth". This "white" and "red" are in sharp contrast and set each other off. "Rustling sound" and "flowing water" are also a kind of spiritual color coordination caused by hearing; There are also "slight trembling" and "quiet tears" caused by "warm hands" and "loving eyes", which are also sensory patterns caused by touch and vision. Through the combination of these colors and patterns, the poet expressed subtle and elusive feelings in a colorful, mysterious and charming way.
The joy of flying like a firefly in the dim shade, the joy of spreading from the petals of roses, the joy of ringing the clock on your feet when you come, they come, but they don't belong to the poet, only to the poet's sadness. This is a touch of color that emerged in the minds of poets in the Baiyun era.
