Look at the picture and guess idiom 3. A curved moon is reflected in the water.

Many emperors form a box, with the moon and many stars below, and a small pool of water under the moon, reflecting the shadow of the moon. The answer is as follows:

Image analysis: so many sons of heaven form a square, then the sky and the square are inseparable (there is a "fantasy"), the moon represents night (with the word "night"), and its shadow is reflected in this small pool (there must be a word for water and pool), so it is not difficult to guess.

So the correct answer is: Arabian nights.

Explanation: It is a metaphor for false birthdays and bizarre discussions.
