Online Moon Blocks — Ask and Cast

The everyday oracle of Minnan and Taiwanese temples: hold the crescent blocks, silently ask your question, and cast — one flat side and one curved side is the sacred answer.

Three throws complete one question

The rules

The Four Verdicts

VerdictPatternMeaning
Sacred (Shèng)One flat, one curvedApproved — proceed
Laughing (Xiào)Both flat sides upQuestion unclear or heart not sincere — ask again calmly
Negative (Yīn)Both curved sides upNot granted — postpone or change course
Standing (Lì)A block stands on edgeExtremely rare, a grave omen — utmost caution

How to Ask Properly

Ask one clear, present-tense question at a time — not "how is my year", but "should I accept this offer today". One question is completed by three consecutive throws: three sacred answers mean yes, two mean proceed with effort, one means grudgingly, none means no. A laughing verdict usually means the question was vague or the heart undecided.

Prefer a richer answer? Try Guanyin fortune sticks or I Ching coins.

Where the blocks come from

Jiaobei (筊杯) are two crescent-shaped wooden blocks — the flat side is yang, the curved side yin, embodying the dance of the two primal forces. The practice dates to Tang-dynasty China and traveled with Minnan emigrants to Taiwan and Southeast Asia, where temple courtyards still echo with the click of blocks on stone. English speakers know them as jiaobei, poe, or moon blocks.
