Guan Yu contains profound and beautiful meanings. What techniques of expression, art and rhetoric are used in his creation?

Is Guan Ju from The Book of Songs? National wind? Nan Zhou, the first poem in The Book of Songs, reflects a young man's love and pursuit for a beautiful girl and is the ancestor of China's love poems. It not only reflects the popular love theme, but also has unique artistic characteristics. Guan Ju: The title is taken from the first sentence of the poem. This is how the title of The Book of Songs came into being.

The poem begins with a pheasant pigeon, and with the sounds of pheasant pigeons and small islands in the river, it evokes a warm feeling in my heart: a lovely girl, a lover in my heart. In the second and third seasons, I picked leeks and set off the pursuit of girls: lovely girls, "I" pursued you day and night, but I couldn't do it, I could only toss and turn, and it was difficult to sleep.

Bixing is a rhetorical device commonly used in The Book of Songs.
