张 = 弓 + 长 : Mnemonic symbol: a spreadsheet. James II of England (zh) practices his archery skills in front of the anglepod (ang1). Riding on a longboard (长) he shoots arrows using his composite bow (弓) trying to hit a spreadsheet (张).

国 = 囗 + 玉 : 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.
