The sky is high and the clouds are light, and the night is thousands of miles away.
The window is like frost in a double shadow, but you can't see it when you look up.
Lonely lights in the middle of the night, the moon and stars are rare.
A melodious cold night will be clear after the haze.
Meaning: The first four sentences are about the starry sky at night, which is magnificent, but the invisible thoughts take first frost's shadow as the people around them. After a closer look, it is gone. The last four sentences, the loneliness of a lonely lamp and the difficulty of the bright moon and stars in the sky at night, only use a sad string to spend the slow and cold night, hoping that the night will pass quickly and I can see the people I miss.
This poem: It expresses a feeling of missing after seeing the full moon at night, so as to feel how lonely you are.
