This couplet is a antithetical couplet.
Zhu Ji Qing Xi Yue Book Part I: Tang Du Fu's "Ancestral Temple" poem: "Bamboo Ji Qing Xi Yue, moss moves jade to make spring." Bamboo sends a sentence: it is said that the moon moves down the Qingxi, and bamboo remains the same.
The second couplet "Shake the ancient valley wind": one of the poems from Bai Song Yuchan's "Two Occasions": "Expose the moonlight and shake the ancient valley wind." Loose shake sentence: it means that the ancient valley wind shakes the branches and leaves of pine trees.
This couplet is a landscape couplet. The first part is about the scenery of quiet streams and the moon, and the second part is about the posture of the branches and leaves of Pinus ponderosa being blown by the wind in the ancient valley. All-in-one communication is dynamic and static, and the artistic conception is quaint.
