市政廳

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!

政 = 攵 + 正 : As James II of England (zh) became a powerful politician (政) he used his power for many crazy laws. For example, he once ordered a stick figure (正) to tear down the engine's bathroom ((e)ng4) using a sledgehammer (攵).

厅 = 丁 + 厂 : Mother Teresa (ti) build a dining hall (厅) in front of the engine ((e)ng1). She nailed (丁) a chocolate factory (厂) to the ceiling of the dining hall so that you just have to stand below it to let the chocolate flow into your mouth.
