Mnemonic symbol: 舟 looks like the tower of a yellow submarine. In front of the outhouse (ou1), James II of England (zh) stands next to his yellow submarine (舟) and asks you: will you swallow the blossom (⺀) and continue your quiet life? Or will you swallow the red pill (丹) and follow him on his adventures in the submarine?
