國籍

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.

籍 = ⺮ + 耤 : Joan of Arc (ji) just arrived at the space station and has to register (籍) in the kitchen (Ø2). Her duty on the space station will be to plow a field (耤) using a bamboo stick (⺮).
