Poe divination

Poe divination (Chinese: 掷筊; pinyin: zhì jiǎo; literally: "throwing poe", also called as "bwa bwei", "cast moon blocks") is a traditional Chinese divination method, in which the divination seeker throws or drops two little wooden pieces on the floor and gets the divine answer by the positions of the pieces whether the future course being contemplated is recommended or not. The pieces, called "Poe" (Bwei) in Taiwanese or Jiaobei in Mandarin, look somewhat like two shells of a clam or bivalve mollusk.

Poe divination can be observed at Taoist temples, such as Guangdi temples and Mazu temples, not only in China and Taiwan, but also in the rest of the world.
