世貿組織

世 = 廿 + L : Mnemonic symbol: the WTO or WHO.

Sherlock Holmes (sh) is cleaning a flower pot (廿) under the shower of the space station's bathroom (Ø4) with a loofah (L) because he didn't quite understand a poster next to the shower from the WHO (世) explaining dangers arising from different germs.

In this case, L is for loofah.

贸 = 卯 + 贝 : Mahatma Gandhi (m) is negotiating with a rabbit (卯) and a crab (贝) at a world trade summit (贸) in the aorta's bathroom (ao4).

组 = 且 + 纟 : Zapatista Zebra (zu) and the silk worm (纟) are starting a NGO (组) in the space station (Ø3). The NGO's goal is to distribute as many space friendly shelves (且) as possible. The shelves are radially symmetric and can be rotated so that the centrifugal force keeps the things in the shelf.

织 = 只 + 纟 : James II of England (zh) founded the international knitting (织) organization (织) in front of the space station (Ø1). Together with him a silk worm (纟) and a cuttlefish (只) are knitting (织) the world's longest scarf.
