Mnemonic symbol: a nation's flag. Let's say the Chinese flag.
In the observatory's kitchen (o2) Gitta Giraffe (gu) is practising her ballet performance. She got a whole crate (囗) full of jade bracelets (玉) and flags (国) and fixed one flag to each jade bracelet. This makes a perfect combination for throwing the ring with the flag waving behind it and catching the ring again after a few pirouettes.

讠

Maud Younger (y) is painting blindfolded onto an advertising column (讠) in the space station's bathroom (Ø4). Justitia comments (议) on her art and indeed voices very just (义) comments (议).

阝

The pope (阝) wants to join the cloister (寺院), but first he has to pass Yu the Great's (yu) test. He has to run as fast as he can from Vatikan City to the anthill's bathroom (an4), where the entrance to the cloister is. As he arrives at the bathroom huffing and puffing, Yu the Great is waving with a checkered flag.
