正

zhe̅ng = zh + (e)ng1

first month of the lunar year

正

zhèng = zh + (e)ng4

straight / upright / proper / main / principal / to correct / to rectify / exactly / just (at that time) / right (in that place) / (math.) positive

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.

罒

wǎng = w + ang3

net (Kangxi radical 122)

This one just looks like a fishing net. Willy walrus (w) is trying to fish frozen fish from the freezer with a net (罒) inside the anglepod's living room (ang3).
