Shibo Yangcong-san

Shibo Yangcong-san is the Discworld version of the Roundworld Oriental game Mahjongg, which is played with ivory tiles, and has similarities to Western card games, although it takes a lifetime to be able to play well. It shouldn't come as a big surprise, therefore, that 'Shibo Yangcong-san' is actually Japanese for Cripple Mister Onion.
