青 = 龶 + 月 : The moon opened a very profitable start-up in front of the engine. He put up a fountain of youth and--wearing a fancy headdress--charges the Queen of Hearts a fortune for drinking from the fountain.

铜 = 同 + 钅 : Tommy Turtle (tu) runs a copper (铜) mine in the engine's kitchen ((e)ng2). He managed to force two twins (同) to work for him and mine the copper using golden harpoons (钅).

峡 = 夹 + 山 : Marie Curie (xi) is gorging (峡) on sandwiches (夹) in the ashram's kitchen (a2). She opens her mouth as wide as a gorge (峡) and puts the sandwiches in her mouth using a big fork (山).

市 = 亠 + 巾 : Mnemonic symbol: a supermarket.

Sherlock Holmes (sh) started a supermarket (市) in the space station's bathroom (Ø4), but all he has for sale right now are berets (亠) and towels (巾). He should have opened it at the beach!
