Mnemonic

Every morning, grandma heads east to the park to practice her tai chi. For fifty years she has repeated the same forms, kneading each movement smoother and smoother until her routine flows like raw silk softened by decades of patient, disciplined repetition.
Additional thoughts
Picture an elderly woman silhouetted against the eastern sunrise, her slow, deliberate movements polishing the air itself. The east sunrise = fresh start each day; grandma's age = lifelong dedication. Silk-kneading imagery ties to the kanji's original meaning.
Quick recall
Grandma faces east at sunrise to practice tai chi, her decades of repetition smoothing every move like kneaded silk.
