余干县

余 = 亼 + 朩 : Mnemonic symbol: 余车 means "emperor's carriage", and I'll thus represent 余 with a sedan chair. In the space station's kitchen (Ø2), Yu the Great (yu) finally has the chance to feel like an emperor. In zero gravity she doesn't need anyone to carry the sedan chair (余) she's sitting on. She set up two sewage pipes (朩) right opposite of each other, so as soon as she shoots out of one she enters the other and is redirected to the first one. In this way she can ride her sedan chair in an infinite loop. An emperor always wears a headpiece, so she puts on a pointed cap (亼).

干 = 一 + 十 : Guy Fawkes (g) is working (干) out in the anthill's bathroom (an4). He's lifting a flute (一) in one hand and a cross (十) in the other.

干 = 一 + 十 : Mnemonic symbol: dried fruit.

Guy Fawkes (g) is drying (干) his clothes in front of the anthill (an1). He hangs them on a large construction made from a cross (十) and a flute (一). Waiting for his clothes to dry, he snacks dried fruit (mnemonic symbol for 干).

县 = 且 + 厶 : Marie Curie (xi) and the county manager of her home county are manufacturing maps of her home county (县) inside of the anthill's bathroom (an4). The county has a very special form which you can reproduce by smashing a fake nose (厶) with a shelf (且).
