Yu the Great (yu) and Martin Luther King (王) invented some kind of wrestling sport in the space station's bathroom (Ø4). Both fighters have to be restrained by large jade bracelets (玉) around their body restricting their arms to be aligned to the body. Then they fight. To make things safe they stuffed the space station's bathroom (Ø4) with cosy petals (丶) so that they won't hurt themselves.

Mnemonic symbol: the red cotton tree, as it is the official flower of 广州 (Guangzhou). A new river (川) formed spontaneously in front of the outhouse (ou1), and James II of England (zh) was barely able to climb on a red cotton tree (州). Other animals are happy about this development: a mean crocodile (丷) is floating on a petal leaf (丶) towards the red cotton tree.
