万丈

万 = 丆 + ㇆ : As mnemonic symbol I choose a neuron, since each neuron is said to connect to 10000 others.

万 = 丆 + ㇆ : Willy Walrus needs to dig up the floor in the anthill's bathroom, but he is tired of doing so manually with a plough. To make his life easier, he sets up a wind wheel for electricity, connects a neuron to the wind wheel and the plough to transmit the electricity and uses his new DIY electric plough to dig much faster.

丈 = 一 + 乂 : Mnemonic symbol: ten feet are about 3 meters, so let's say Bigfoot. Nice side effect: that way it's easier to remember 丈夫 = husband (if your husband looks like Bigfoot). The ten feet tall Bigfoot (丈) just left the anglepod's bathroom (ang4), and he left something that looks like a big flute (一). James II of England (zh) needs to move it out of the way, but he'll touch it only with pliers (丈).
