国际公认

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.

际 = 示 + 阝 : Joan of Arc (ji) and the pope (阝) have an international (际) meeting in the space station's bathroom (Ø4). They decide on the border through the bathroom and mark their territories using standards (示).

公 = 八 + 厶 : Mnemonic symbol from 公交车: a (magic) bus.

公 = 八 + 厶 : Gitta Giraffe has to deliver 100 eight balls to engine driving a magic bus. She is driving in front of the engine and because the load is so heavy, she is driving very slowly. Additionally, she tried to decrease the wind resistance by installing a large fake nose at the front of the bus.

认 = 人 + 讠 : Robinson Crusoe is lost in the encampment's bathroom. He doesn't know anyone, and he doesn't recognize the environment! At first, he turns to an advertising column, but it doesn't tell him anything useful. But fortunately, Neanderthal Man comes in, instantly recognizes Robinson Crusoe, and tells him where he is.
