Which ancient poem does Qingqing Zidiao come from?

The Book of Songs: Zheng Fengji.

The green article in my heart comes from The Book of Songs, Zheng Feng. This poem is about a man waiting for his sweetheart on the rostrum. He is so anxious that he keeps walking back and forth. A day without seeing him seems like three months.

The whole poem consists of three chapters, using flashback technique. The first two chapters describe themselves as "I". Qing Ji and Qing Pei are based on couples' clothes. The clothes of the other party left such a deep impression on him that he couldn't forget it. I can imagine his desire for love.

In Qing Dynasty, Cheng believed that the poem "Zheng Feng Zi Heng" was a poem describing the mutual love between lovers. If we don't meet for a day, such as every March, we can see how enthusiastic we used to be.

The whole poem is less than fifty words, but the anxiety of the protagonist waiting for his lover seems to be in sight. This artistic effect is achieved because the poet used a lot of psychological descriptions in his creation.

In the poem, only the words "pick" and "reach" are used to express this person's actions, and his psychological activities are described by the main pen and ink, such as the lovers' complaints in the first two chapters and the monologue "I don't see you for a day, it seems like March" in the last chapter.

Two complaints, with "longitudinal me" and "Zi Ning" as the antithesis, are not without reservations in the sense of anxiety, giving birth to infinite reverie, which can be described as less words and more meanings.

The inner monologue at the end, through exaggerated rhetoric, causes the contrast between subjective time and objective time, thus vividly showing its strong emotional psychology, which can be said to be amazing because of exaggeration and embellishment. Psychological description techniques developed incisively and vividly in the later literary world, and traced back to the source, this poem has already begun.
