First of all, both poems show deep yearning. With the help of the act of picking hibiscus on the river, "Picking Hibiscus on the River" describes the hero's yearning for the people he loves far away, showing eager hope and helpless loss. Queqiaoxian expressed the pain of parting and the desire for reunion through the story of Cowherd and Weaver Girl.
But the two poems are expressed in different ways. Picking hibiscus in Shejiang mainly uses lyric and line drawing techniques to express the protagonist's feelings by describing the scenes and actions of picking hibiscus. While "The Fairy of the Que Bridge" mainly adopts suspense techniques, and depicts an ideal state of love by imagining the meeting of cowherd and weaver girl on Tanabata, thus highlighting the expectation of faithful love.
Generally speaking, the two poems are similar in theme, but different in expression. Picking hibiscus on the river expresses deep yearning through specific scenes and behaviors, while Queqiaoxian depicts an ideal state of love through romantic imagination.
