正步走

正 = 一 + 止 : Mnemonic symbol: a stick-figure with straight lines. James II of England (zh) really has to use the engine's bathroom ((e)ng4), but there's a stick-figure (正) blocking the stalls with a barrier (止). The stick-figure measures with a flute (一) whether James is tall enough to go. James stands very straight (正) to make himself as tall as possible.

步 = 止 + 丨 + 丶 + 丿 : Mnemonic symbol: a five-paced viper, 五步蛇.

Bruno Bear (bu) was strolling (步) around the space station's bathroom (Ø4) with a dinosaur bone (丨) as walking (步) stick in his hands. He disregarded the barrier (止) marking the wild, forbidden area lightheartedly and just jumped over it whistling a joyful tune. But shortly afterwards he made a terrible realization: only five paces (步)away there was a five-paced viper (步) hiding under a petal leaf (丶)! Bruno knew the viper was after him, so he tried to keep it at distance using his dinosaur bone and feeding it bananas (丿) while at the same time slowly backing up to the barrier.

走 = 龰 + 土 : Mnemonic symbol: a Nordic walking pole. Zorro (z) is fighting Neanderthal Man (bottom of 龰) in the outhouse's living room (ou3). Neanderthal Man uses his pennant (top of 龰), and Zorro uses a Nordic walking pole (走). Zorro overcomes Neanderthal Man by using a dirty trick: he throws some dirt (土) at Neanderthal Mans face, who is blinded and hurts his foot with his pennant (the pennant pierces his foot: 龰). Just at this moment Zorro uses the opportunity to sedate Neanderthal Man and rams a syringe (龰) into his shoulder.
