下犬式

下 = 一 + 卜 : Mnemonic symbol: from the up/down logic, and a little bit the shape of the character, a ladder.

Xi Shi (xi) is on a retreat in the ashram. Using a voodoo staff (卜), she divined that next (下) week she'll have to play the flute (一) sixteen hours per day. Because she hates playing the flute, she climbs over the ashram's bathroom (a4) wall using a ladder (下) to escape.

犬 = 丶 + 大 : Cupid (qu) wants to play fetch with the Saint Bernard dog (犬) in the anthill's living room (an3) and throws a petal (丶) over his head, but the dog just continues sleeping. Much to Cupid's surprise though, a big robot (大) happily leaps after the petal.

犬 = 丶 + 大 : Looks like a Saint Bernard dog with only one eye.

式 = 工 + 弋 : I'll use a specific style as mnemonic symbol: 哥特式, gothic.

Sherlock Holmes and the goth are celebrating a Viking festival in the space station's bathroom. They don't have trunks to throw around, so they use a steel beam. They also celebrate by practising archery. In zero gravity it is easy for them to set one world record after the next.
