Poe divination

Poe divination (/pu̯e/, from the Hokkien Chinese: 跋桮; Pe̍h-ōe-jī: poa̍h-poe, Min Dong BUC: buăk-buŏi, 'cast moon blocks', also written bwa bwei, Mandarin Chinese: 擲筊; pinyin: zhì jiǎo / zhí jiǎo; lit.

The pieces, called 桮; poe (bwei) in Taiwanese or jiaobei in Mandarin, look somewhat like two shells of a clam or bivalve mollusk.

The second is 陰笅; yīn jiǎo, is when both blocks have their curved sides facing up; this shows the Deity's disagreement with the devotee's question or plea.

The last would be 笑笅; xiào jiǎo, when both blocks have their flat sides facing up; this shows the Deity's amusement at the devotee's question or plea.

A unique, rare result would be the 站笅; zhàn jiǎo, which occurs when one of the blocks stands with both its flat and curved sides facing in a horizontal position.
