The kanji in this 4-character idiom are:
鏡 = mirror
花 = flower
水 = water
月 = moon
It evokes the image of the full moon reflected in water, or a flower reflected in a mirror – something beautiful but out of reach.
I chose this idiom to write today because it contains the kanji for “moon” and I am still on a mooncake binge.
