周径

周 = ⺆ + 土 + 口 : Mnemonic symbol: a hula hoop. James II of England (zh) performs in front of the outhouse (ou1): he swings a hula hoop (周), juggles three mandarins (口) and balances a small heap of dirt (土) on his head. He cheated a little bit though, because he stapled the heap of dirt to his wig with a stapler (⺆).

径 = 圣 + 彳 : Father Christmas (圣) gives black sneakers (彳) to Joan of Arc (ji) in the engine's bathroom ((e)ng4). Joan of Arc happily puts her new shoes on instantaneously and circles father Christmas on a track (径) with a very small diameter (径), making father Christmas feel quite uncomfortable.
