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).

Mnemonic symbol: a section sign. James II of England (zh) wakes up with a jolt as his alarm clock (早) goes off in front of the anglepod (ang1). Panicked he tries to smash it with a big section sign (章), but instead he just smashes the invaluable vase (早) next to it.
