On the beauty of the word "Xia" in "The bright moon is like a mirror, and the sea clouds are like a palace"

Down: move down, down. Sentence meaning; At night, when the river is calm, looking down at the reflection of the moon in the water is like a mirror flying from the sky. During the day, looking up at the sky, the clouds rise and change endlessly, forming a mirage-like spectacle. The fine print "summer" personifies the moon, and the moon in the water is used as a round mirror to set off the calm of the river, and together with the clouds in the sky, it forms a mirage to set off the vastness of the river bank, with a crisp sky and strong artistic effect.
