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.

Willy Walrus (w) is babysitting a baby in front of the ashram (a1), but the baby is crying (哇) all the time. Willy Walrus already tried to have it play with a jade tablet (圭) and to feed it a mandarin (口), but the baby was not interested at all.
