“The sound of snow is close to the bamboo.” The snow falls on the bamboo forest, and the wind carries the rustling sound, which makes people who can’t sleep feel particularly lonely and desolate. This fully exaggerates the atmosphere of the cold night in Nanjing. The word "bias" more carefully depicts the sad person's unique spiritual feeling towards this kind of sound, which seems to be resentful but helpless. "Cold dreams never leave home." In intermittent dreams, I always dream about scenes at home. Putting the word "cold" before "dream" not only indicates that it is a dream on a cold night, but also reflects the poet's psychological "cold", which gives "dream" an emotional color of quiet sadness.
Five or six sentences describe the intermittent dream and the situation when you wake up and can't fall asleep again. "The dawn angle is divided into residual leaks". Write what you hear. In ancient times, hourglasses were used to keep time, and the watch was clocked at night. The residual leakage refers to the sound of the drum when the night is about to end. After dawn, the trumpets sound and the drums stop, indicating that the long night is over and morning is coming. "Divided" refers to the difference in hearing, which reflects the division of time. It reveals that after the poet's dream ended and before he heard the sound of the horn, he had been lying in bed helplessly listening to the sound of the horn. His miserable feeling can be seen. "A solitary lamp falls off broken flowers" writes about what he saw, and the green lamp shone on the wall. The poet looked at the lonely dim oil lamp for a long time and the broken lamp flowers fell off. The word "lone" not only expresses the deserted environment of the poet, but also reflects his subjective feeling of loneliness. This couplet expresses the author's homesickness implicitly through hearing and seeing it, and the emotion is beyond the words.
