努力

努 = 力 + 奴 : There is an emergency in the space station (Ø3), but both Nelson Newt (nu) and the slave (奴) are too weak to push the emergency power button (力). They exert (努) all their power to push the button together and let ground control know of the emergency.

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! She uses all her power to build an electricity plug, and for the two pins she uses a plough (㇆) and a banana (丿). Finally she hits a big power button (力) to turn the power on.
