中央省

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.

央 = ⺆ + 大 : Mnemonic symbol: 中央处理机, central processing unit (CPU).

In front of the anglepod, Maud Younger received her new robot. Soon she is not satisfied with his artificial intelligence; to increase it, she staples a CPU to the center of its chest, although the robot begs her not to do so.

省 = 少 + 目 : Sherlock Holmes (sh) opened a new office in the engine ((e)ng3), and to celebrate it he distributed saving (省) vouchers with little smileys (少) on them. Shortly afterwards the eye of providence (目) visits his office, all of the vouchers in his hands to save (省) on the bill, demanding Sherlock's services.
