This poem embodies Gu Cheng's aesthetic ideal-to pursue a pure, harmonious, non-contradictory and pleasant world. The childhood experience shattered Gu Cheng's ideal dream, but he still pursued his fantasy persistently, hoping to realize it again in his other world. In this poem, the poet observes and feels the world with a child's eyes and heart, hoping to draw a colorful blueprint of life in the fantasy world with colored crayons, and draw "clumsy freedom", "eyes that will never cry" and "love without pain". However, can this whimsical blueprint be realized in the real world? The poet left fantasy and returned to reality. "I didn't get the crayon" means that my ideal blueprint has not been recognized by the society, so I can only "tear up that blank sheet of paper in Zhang Xinai" in despair. "White paper" refers to "self", life or unwritten poems. But did the poet stop pursuing fantasy? No. The last verse of the poem once again points out that "I" is "a child spoiled by my imaginary mother". I am willful and will continue to pursue fantasy persistently.
Gu Cheng's childhood had various opportunities to blend with nature, and he found a free realm in nature, where he could temporarily forget all kinds of sadness and troubles in reality. This realm of freedom has become his persistent pursuit of fantasy world. Because the poet has this special relationship with nature, nature is assimilated into the poet's psychological structure, and his poems are full of idealism.
