中局

中 = 丨 + 口 : Mnemonic symbol: a dart board, because you always try to hit the center.

Julian Giant Squid (zhu-) is throwing dinosaur bones (丨) as darts on a dart board in front of the engine ((e)ng1). To make it a bit more difficult he's throwing mandarins (口) into the air as well and skewers them up right in the center (中 is a mandarin skewered on a dinosaur bone) in mid flight with the dinosaur bones. He's still able to consistently hit the center (中) of the dart board.

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.
