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).
