殘餘

残 = 戋 + 歹 : The King of Chu (c) invited the wicked witch (歹) to try his floating tank (戋) in the anthill's kitchen (an2) and without waiting he pushed the wicked witch in and closed the lid. After a while he checked on her and found to only the complete tank, but also the wicked witch absolutely ruined (残).

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).
