號召力

号 = 丂 + 口 : Hamlet accidentally locked himself into the aorta's bathroom, together with a mandarin which he is extremely allergic against. His only rescue is the emergency breathing mask attached to the wall which he puts on immediately. There is also a trumpet to call for help with a bugle call, but Hamlet has to wear the breathing mask, so he can't give the bugle call in a normal way. Instead, he has to give the bugle call with his butt.

召 = 刀 + 口 : Mnemonic symbol: an intercom to call everyone together. James II of England (zh) prepares a few mandarins (口) for everyone in the aorta's bathroom (ao4) by cutting them with a cleaver (刀). As he is finished he calls all the blood platelets together (召) over the intercom (召) to come over and fetch a piece.

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.
