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.

吉 = 口 + 士 : Mnemonic symbol: "Giga" stems from a Greek word for "giant", so I'll represent 吉 by a giant.
