Jiaobei Guide: Asking the Moon Blocks

Walk into any temple in Fujian, Taiwan or the Chaoshan region and you will hear a crisp clack of wood on stone: two crescent blocks thrown to the ground, read where they settle. This is jiaobei (筊杯) — known in English as moon blocks or poe divination — the most direct yes/no oracle in the Chinese tradition.

The four verdicts

• Sacred blocks (圣筊) — one flat side up, one curved side up: the classic yang-yin embrace. Approved.
• Laughing blocks (笑筊) — both flat sides up: the deity smiles; your question is unclear or your heart not settled. Rephrase and ask again.
• Negative blocks (阴筊) — both curved sides up: not granted. Postpone, change the plan, or ask about something else.
• Standing blocks (立筊) — a block lands on its edge: vanishingly rare, treated as a strong warning to reflect before proceeding.

The three-throw ritual

One question is completed by three consecutive throws: three sacred verdicts is a full yes, two a conditional yes, one a grudging maybe, none a no. In temples the asker first states their name, address and question aloud, then throws. The same etiquette applies online — our moon blocks count the three throws for you.

How to phrase the question

Jiaobei answers concrete, present-tense questions, not vague horizons. "Should I accept the offer from Company X today?" works; "Will I be rich?" only earns a laugh. If you keep receiving laughing blocks, tradition says the issue is the question or the querent — not the oracle.

A tradition that traveled

Block divination is attested from the Tang dynasty and spread with Minnan emigration through Taiwan, Hong Kong and Southeast Asia. Wherever a Mazu or Guanyin temple stands, the blocks still click. For a richer, narrative answer after a yes, draw one of the 100 Guanyin fortune sticks.

From the classics

「手持杯珓导我掷，云此最吉余难同。」"Handing me the cup-divination blocks, he bade me throw them: 'This is the most auspicious — the rest cannot compare.'" — Han Yu (768–824), poem at Mount Heng's temple. The verse records block divination as a living practice in Tang China.—— 唐·韩愈《谒衡岳庙遂宿岳寺题门楼》
