山牆

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.

墙 = 啬 + 土 : The Queen of Hearts (qi) and the stingray (啬) got married and took over the anglepod to start a new kingdom. In the kitchen (ang2) they start building their city wall (墙) out of lots of dirt (土). They also add lots of thorns to make the wall as stingy (墙) as possible.
