精於此道

精 = 米 + 青 : Joan of Arc scoops a bit of water from the fountain of youth in front of the engine and pours it into a bowl of rice. The water refines the rice into rice wine, and as Joan of Arc drinks it, she finds her spirit renewed.

于 = 亅 + 二 : Mnemonic symbol: prepositions (in, at, on, to, ...) are what glue the sentence together. Honey is as sticky as glue, so I'll represent 于 by a honey jar.

Yu the Great (于) was assigned to repair the electronics of the space station's kitchen (Ø2), but instead he was snacking honey from a honey jar (于). Unfortunately his capacitor (二) got stuck in the honey and now he has to use a crowbar (亅) to lever it out.

此 = 匕 + 止 : These boots are made for walking! The King of Chu cannot get his boots off in the space station. First he tries with the help of a large ladle, then he switches to a big barrier, which finally works.

道 = 辶 + 首 : The chief and Don Quixote decided to follow the path of the Dao in the aorta's bathroom. They wear gladiator sandals and meditate sitting on the floor of the bathroom, envisioning the path to enlightment.
