廠礦

Mnemonic symbol: a chocolate factory. Charlie Chaplin (ch) is overjoyed to see that in the anglepod's living room (ang3), a small chocolate factory (厂) is for sale. He buys it, shaves his mustache, grows his hair a bit and renames himself to Willy Wonka to live in the chocolate factory.

矿 = 广 + 石 : Karl Koala (ku) got a new job at the coal mine (矿) in the anglepod's bathroom (ang4). The entrance to the tunnel lies quite high, so every time Karl brings out another coal stone (石) he attaches it to a small parachute (广) and lets it fly down to the floor.
