玉山县

玉 = 丶 + 王 : Mnemonic symbol: a jade bracelet.

Yu the Great (yu) and Martin Luther King (王) invented some kind of wrestling sport in the space station's bathroom (Ø4). Both fighters have to be restrained by large jade bracelets (玉) around their body restricting their arms to be aligned to the body. Then they fight. To make things safe they stuffed the space station's bathroom (Ø4) with cosy petals (丶) so that they won't hurt themselves.

山 = 丨 + 凵 : Mnemonic symbol: 山 looks like the tip of a fork. Sherlock Holmes (sh) is climbing a mountain (山) in front of the anthill (an1). He uses a dinosaur bone (〡) as walking stick, and to have better grip he attached a fork (山) to its tip. Unfortunately he accidentally sticks the fork into a receptacle (凵) on the ground of the mountain and gets shocked.

县 = 且 + 厶 : Marie Curie (xi) and the county manager of her home county are manufacturing maps of her home county (县) inside of the anthill's bathroom (an4). The county has a very special form which you can reproduce by smashing a fake nose (厶) with a shelf (且).
