古代

古 = 十 + 口 : Mnemonic symbol: at least on German maps, this character actually resembles a cloister.

Oh no! Gitta Giraffe (gu) found that the golden cross (十) broke off of the cloister (古) in the space station's living room (Ø3)! She skewers a mandarin (口) on top of the cloister so that she can skewer the broken off cross back on to fix it.

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.
