The lyrics of Jay Chou's Li Qixiang tell a pure and romantic love story. Saury is a kind of marine fish. Its body is as long as a knife and it tastes delicious. "Cats and you want to know the taste of saury." This sentence is not a description of autumn scenery, but a figurative description. Saury is compared to love, and cat is compared to me in the first person. This light-hearted metaphor not only sets off the liveliness and loveliness of the hero and heroine in the story, but also exaggerates their desire for love.

Saury is the only species in sauropod, and it is also one of the important food fish. Saury matures and lays eggs in autumn. The author compares the autumn fish in this production season to the feelings that the hero and heroine are eager to get, which is self-evident.
