Mnemonic

A mountain flower blooms under the moon, its roots buried in earth. You dig up that earth—soft as clay—and begin molding it into a statue of the mountain flower lit by moonlight. The moon watches as your molding takes perfect shape.
Additional thoughts
Picture the kanji's layers top to bottom: mountain flower crowning the top, moon in the middle, earth forming the base. Earth is your raw clay, moonlight is your lamp, and the mountain flower is the model you sculpt. This visual stack mirrors the actual kanji structure.
Quick recall
Under a mountain flower lit by the moon, you scoop soft earth and start molding it into a clay statue.
