国营

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.

营 = 艹 + 冖 + 吕 : Maud Younger (y) built a camp (营) in the engine's kitchen ((e)ng2). She is sitting on a sheet of artificial lawn (艹) with a cooking top (冖) serving as her roof, and playing idly on her pitch pipe (吕).
