不得而知

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.

得 = 㝵 + 彳 : Don Quixote found a magic lamp and rubs it inside the elevator's kitchen. A genie appears and grants Don Quixote his wish for black sneakers. Unfortunately they are second hand and so smelly that Don Quixote instantly catches a disease.

得 = 㝵 + 彳 : Because Don Quixote is so disappointed by the black sneakers he got from the genie from the magic lamp, he kicks both very mad from the rooftop of the elevator.

得 = 㝵 + 彳 : Because Don Quixote kicked the genie's lamp from the rooftop of the Erechtheion as far as to inside of the Eiffel Tower, the genie demands Don Quixote to apologize. Inside of the Eiffel Tower, Don Quixote kowtows to the genie, who takes back the black sneakers he gave to Don Quixote earlier.

而 = 𦉫 + 丆 : A comb. Albert Einstein is getting ready to go out just inside the entrance of the space station. He put up some loud music on the stereo and tries to comb his hair with his comb and the help of a wind wheel.

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).
