Don't walk quietly into the beautiful night. Where did it come from?

Don't walk quietly into that beautiful night. This is a poem written by dylan thomas, an English poet in the mid-20th century. In this poem, the poet expresses his anger at the death that took the lovely people away from this world, that is, "angrily denouncing the disappearance of light." There is helplessness in life experience, which reflects the treasure of life, especially the sadness and anger that my father is about to leave this world because of illness, which reflects his love for his parents and his inner helplessness to some extent.
