功力

功 = 力 + 工 : Gitta Giraffe (gu) practices her Kung Fu skills (功) in front of the engine ((e)ng1) with a sparring robot made out of steel beams (工). The robot is programmed to fight Kung Fu (功), but Gitta Giraffe's Kung Fu is better: she hits the robots power button (力) and turns it off.

力 = ㇆ + 丿 : Mnemonic symbol: a power button.

Li Qingzhao (li) just had a shower in the space station's bathroom (Ø4) and wants to use the hair dryer, but there's no plug, just the bare end of the cable!
