中途退场

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.

途 = 余 + 辶 : Just inside the entrance of the space station (Ø2), Tommy Turtle (tu) is contemplating two different ways (途) to get back to earth. There is a sedan chair (余) but no one to carry it on the one hand, and there is a pair of worn gladiator sandals (辶) on the other hand.

退 = 艮 + 辶 : Tommy Turtle (tu) recently retired (退) and retreated (退) into the Eiffel Tower's bathroom (ei4). There he just wears gladiator sandals (辶), blows chewing gum bubbles (艮) and ponders the sense of life.

场 = 𠃓 + 土 : Charlie Chaplin (ch) practices his stage act in the anglepod's living room (ang3). He built a circus ring (场) out of clay (土) and performs his show, wearing Icarus' wings (𠃓) and flying around.
