Make an appreciative comment
The bright moon is in the sky and the river is clear, which makes the moon reflected in the water more crystal clear and bright. In the forest, egrets walk in rows and fly freely in the bright moonlight. This poem depicts the charming scene of a quiet and beautiful moonlit night. The word "Jing" is a causative usage, which not only describes the clarity of the river, but also highlights the brightness of the moon, which shows the author's exquisiteness.
Note: Lu (Lü), Qing. Su Yue describes the bright moon.
