Brunhilde (bi) has been on a treasure hunt for weeks now because she found an old map (冂). For her hunt she brought a sack of rice (米) which she already more or less used up. After digging up the floor of the space station's bathroom (Ø40) with a sledgehammer (攵) at the point indicated on the map, she finally finds the treasure: a pair of old worn-out shoes (敝) which were incredibly valuable to the owner, but are worthless for Brunhilde.
