人事不知

人 = 丿 + ㇏ : Mnemonic symbol: Neanderthal Man (人). Robinson Crusoe (r-) is looking for snacks in the encampment's kitchen (-en2) when he suddenly spots Neanderthal Man (人). Neanderthal Man offers him a banana (丿), but Robinson Crusoe doesn't trust the present and pokes it with a finger (㇏).

事 = 𠮛 + 彐 + 亅 : Mnemonic symbol: The thing.

事 = 𠮛 + 彐 + 亅 : Sherlock Holmes read a magic scroll in the bathroom of the space station. The scroll promised eternal love to anyone who reads it and wears a pig's nose while doing so, and Sherlock gave it a try. Now he summoned the thing, and he is scared to death! All he has to defend with is a crowbar. However, he never was in danger: Since he is wearing the pig snout, the thing thinks Sherlock is his mommy, and it just wants to cuddle.

不 = 丆 + 卜 : Bruno Bear (bu) is setting up a wind wheel (丆) with a voodoo staff (卜) in the space station's bathroom (Ø4). He also puts a "forbidden" sign (mnemonic symbol for 不) on it, to make clear that it may not (不) be stopped.

知 = 口 + 矢 : Mnemonic symbol: Francis Bacon is attributed to have stated "scientia potentia est", "knowledge is power". I'll thus represent 知 by Francis Bacon. Francis Bacon (知) and James II of England (zh) are playing darts (矢) in front of the space station (Ø1). Because they lack a dart board they just use a mandarin (口).
