流於

流 = 㐬 + 氵 : In the outhouse's kitchen Li Qingzhao is rinsing her large bowl (which is decorated with pennants and pendants). She uses a bottle of water to rinse it. She rinses it very thoroughly so that a lot of water flows over.

于 = 亅 + 二 : Mnemonic symbol: prepositions (in, at, on, to, ...) are what glue the sentence together. Honey is as sticky as glue, so I'll represent 于 by a honey jar.

Yu the Great (于) was assigned to repair the electronics of the space station's kitchen (Ø2), but instead he was snacking honey from a honey jar (于). Unfortunately his capacitor (二) got stuck in the honey and now he has to use a crowbar (亅) to lever it out.
