It tells the story that the author is lonely, misses his hometown, treats the star as a friend and chats with him. The author can't help thinking of his home, his relatives and his childhood. Writing stars three times in the works shows different artistic conception and feelings due to different subjective conditions (age, experience and mood) and objective conditions (time, place and atmosphere).
The author infected the objective scenery with his own feelings, and then turned it into a sentient thing, integrated with me, so that people can know the feelings of the lyric protagonist-"I" in prose from the feelings of appreciating things.
I hope it helps you!
