This is a material composition, the material is Chen's poem "Window", and the shutters are open, which is a poetic sentiment to the vast space and a spiritual pursuit of life. Although The Window is a work expressing lovelorn love, she sang a sad song with another woman's deep tone. Although "my window is open to the night/to the silent starry sky", she despises the dark reality, whips the darkness, sings praises in the darkness and yearns for the light. Reading her poems, there is no sense of suffocation swallowed up by darkness, and longing and hope have overwhelming power. ? So it can be imagined as: spiritual pursuit, yearning and hope for life.
