The court is as empty as water.

Ming: clear and bright. This sentence comes from Su Shi's Night Tour of Chengtian Temple in the Song Dynasty: "The courtyard is as empty as water, and the algae in the water cross each other, covering the bamboo and cypress."

The moonlight shines as clear and transparent as clear water in the courtyard. The algae and shepherd's purse in the water crisscross, which turned out to be the shadows of bamboo and cypress.

This sentence uses figurative rhetoric, with "stagnant water" as a metaphor for the moonlight and "flowers and weeds crossing each other" as a metaphor for the shadow of a pine tree, which vividly shows the brightness of the moonlight and outlines a beautiful realm that is empty, clear, thin and swaying, true and illusory. "The water is empty and bright", and a pool of water is clear and transparent. First, the water color is written, and then the things in the water are "algae and weeds cross each other", crisscrossing and swaying.
