七十年代

七 = 一 + 乚 : Mnemonic symbol: the Seven-Branched (七) Laser Sword. The Queen of Hearts (qi) is testing her new Seven-Branched Laser Sword (七) in front of the space station (Ø1). She's slicing flutes (一) and shovels (乚).

十 = 一 + 丨 : Mnemonic symbol: a holy cross. Sherlock Holmes (sh-) is investigating a very strange thing he found in the kitchen of the space station (-2): A big pyramid made of ten (十) crosses (十), which are in turn made out of flutes (一) and dinosaur bones (丨).

年 = 午 + 丨 + 一 : Nefertiti (ni) is having lunch (午) in the anthill's kitchen (an2). Unfortunately they didn't have any cutlery left so she has to use a dinosaur bone (丨) and a flute (一) instead of fork and knife. It will take her a whole year (年) to finish her lunch this way.

代 = 亻 + 弋 : Rosa Luxemburg (亻) wants to practice her archery skills in the airplane's bathroom (ai4). On the other side Don Quixote (d) is standing, but they don't have an apple, so they substitute the apple with a token (代, 代币). Don Quixote is trembling heavily as Rosa lifts her bow (弋) and prepares to shoot down the token from Don's head.
