Chinese Jiaobei Blocks: What They Are and Where They Sit

If you have visited a Chinese temple in Hong Kong, Taiwan, or southern Fujian, you have probably watched someone toss two crescent-shaped red blocks onto the floor. That practice is *jiaobei* — 筊杯, sometimes romanized *poe* or *bwa bwa* depending on dialect, and it is one of the oldest live divination tools still in everyday use.

The blocks are not a fortune-telling system on their own. They are a confirmation device. Worth understanding what they actually do before you treat them as standalone divination.

The shape and material

A jiaobei pair is two pieces of wood, traditionally hardwood from a tree the temple has consecrated. Each block is shaped like a crescent moon — flat on one side, curved on the other. Painted red on both sides, sometimes with gold characters.

When you toss them, each block lands either flat-side-up or curved-side-up. With two blocks, that gives three possible outcomes, and those three outcomes are the entire vocabulary of the practice.

The three outcomes

Sheng bei (聖杯) — affirmative. One block flat-side-up, one block curved-side-up. The most common reading: yes, the deity affirms what you asked.

Yin bei (陰杯), negative. Both blocks curved-side-up. The reading: no, or — more accurately, the deity does not affirm. Sometimes read as *the question is wrong* rather than *the answer is no*.

Xiao bei (笑杯) — laughing blocks. Both blocks flat-side-up. The reading: the deity is amused. The question is not well formed, or the answer is too obvious to bother with, or the timing is off. Not a yes, not a no, but a request to ask again differently.

Three outcomes, no in-between. The simplicity is the point.

Where jiaobei sits in the divination ecosystem

In the typical temple flow, jiaobei is not used alone. The full sequence at a Wong Tai Sin or similar temple runs roughly like this:

1. State your question silently to the deity.

2. Throw jiaobei to ask whether the deity will answer this question today. If you get xiao bei or yin bei here, the question may need rephrasing.

3. If sheng bei, draw a fortune stick from the canister.

4. Throw jiaobei again to confirm the stick is the correct one for your question. Sometimes you draw three or four sticks before jiaobei confirms one.

5. Read the confirmed stick.

The blocks bracket the practice. They open the conversation and close it. The fortune stick, the 100-poem corpus — is the actual oracle. Jiaobei is the handshake.

This is why a jiaobei reading on its own, without a question framed for a specific stick or decision — usually gives less signal than people expect. The blocks were designed to confirm, not to answer freestanding questions.

How online jiaobei works

Digital jiaobei tools simulate the toss. The mechanism is uniform random selection across the three outcomes, weighted to match a real toss's physical probability, roughly 50% sheng bei, 25% yin bei, 25% xiao bei.

The online version preserves the binary mechanic but loses the temple ritual that surrounds it. As with online fortune sticks, the discipline is portable: one question, one set of throws, one outcome, no immediate re-rolling.

The kaucim.ai jiaobei tool is built around this simple loop — ask, throw, accept the outcome.

A small but useful habit

If you are using jiaobei online and getting xiao bei twice in a row, do not throw a third time. Instead, write down your question, actually write it — and read it back. Most of the time, xiao bei twice is the practice telling you the question is the problem, not the answer. Reframe and ask again later.

That is the discipline the temple architecture used to enforce on you. Online, you have to enforce it yourself.

Frequently asked questions

What does jiaobei mean?

Jiaobei (筊杯) means literally 'crescent cups' — two crescent-shaped wooden blocks used in Chinese temple divination. Each toss produces one of three outcomes: sheng bei (yes), yin bei (no), or xiao bei (the deity laughs / the question is unclear).

Are jiaobei the same as moon blocks?

Yes — moon blocks is the common English translation of jiaobei. Same physical objects, same mechanics, same three outcomes. Different communities use different romanizations: jiaobei (Mandarin), poe (Hokkien), bwa bwa (Cantonese).

Can jiaobei answer any yes-or-no question?

In principle yes; in practice, jiaobei works best when paired with a specific fortune stick or candidate decision. Free-standing yes/no questions tend to produce a lot of xiao bei because the question often is not as binary as it sounded.

How many times can I throw jiaobei?

Tradition says three throws maximum on the same question. If you have not gotten a clean yes by then, the question itself usually needs to be rewritten before asking again.

Is jiaobei the same as fortune sticks?

No. Fortune sticks are the primary oracle — drawn from a canister of 100 numbered sticks tied to classical poems. Jiaobei is the confirmation tool used before, after, or alongside a fortune stick draw to bracket the question and verify the answer.
