局限于

局 = 尸 + 乛 + 口 : Zeus (ju) got a job at the post office (局) just inside the space station's entrance (Ø2) and already at his first day a ghost (尸) approaches him. Zeus feels extremely threatened and tries to kill the ghost with a sickle (乛), but the sickle just cuts through the ghost. As the ghost is finally right in front of Zeus it produces a mandarin (口) which it wants sent to earth.

限 = 艮 + 阝 : Marie Curie (xi) caught the pope (阝) munching chewing gum (艮) in the anthill's bathroom (an4). Marie hates it when someone puts their chewing gum just anywhere in the room, so she marks a confined space with red and white tape and sends the pope to stay within the limits (限) while he is chewing.

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.
