Missing and homesickness. Needless to say Mingyue, there are too many examples. Crickets are also written about a lot in the Book of Songs. I remember that there is a modern poem about nostalgia. The content is that hearing the chirping of crickets reminds me of my hometown. The cries of autumn cicadas make people nostalgic, and stars are rarely seen. I only remember "seven or eight stars in the sky, two or three points of rain in front of the mountain." The general meaning is also related to longing.
