At the beginning of the poem "forefinger believes in the future", several images, such as cobwebs, stoves, smoke and ashes, are used to describe that barren, poor and difficult time. People who have not experienced that era will have a strong sense of hardship in their hearts. Poets, on the other hand, "write down and believe in the future with beautiful snowflakes". Snowflakes not only symbolize purity and simplicity, but also convey a clear and definite consciousness, showing the firmness of unyielding reality. This is a belief that comes from hard life. The second poem uses purple grapes, dewdrops in late autumn, flowers, other people's feelings and condensed vines to write the light and gloom of life, from enthusiasm and frustration to fullness and exhaustion, which is aroused. Unpleasant association and the poet's personality power of "writing down and believing in the future in a desolate land" can't help but strongly shock everyone's heart. This is a belief that stems from the hardships of life. The third section "I want to wave the waves running to the horizon with my fingers/I want to hold the sea holding the sun with my palm" shows the poet's lofty sentiments. The phrase "a warm and beautiful pen is swaying with the dawn" compares "dawn" to "a pen", and the imaginative "writing with a child's pen to believe in the future" expresses the poet's sincere and frank thought, which is a sincere belief. These three verses sang "Believe in the future", just like the main theme of a piece of music, playing the strongest voice in the poet's heart. In that gloomy and painful era, I believe that the future has cast a light of hope in people's hearts. I think most of the educated youth who came out of that era, or a generation, will still feel heartache when they reread Believe in the Future at any time. Cruel, stubborn, painful and scarred belief is a firm and unyielding belief in the future in a painful reality. It is also the most moving core of this poem.
