Jiaobei is a traditional Chinese way of asking questions and getting responses from the gods, ancestors, or spirits. It involves using a pair of yarrow stalks or flat sticks, which are split into two groups or piles.
First, you hold the stalks or sticks together between your hands and make a wish or ask a question. Then you shake them to create random pattern of either straight or curved lines that indicate answers or responses.
The pattern created with the sticks or stalks is interpreted using a book or chart that has possible answers or meanings, which are associated with each pattern. And this interpretation helps to give you guidance, advice, or warning in accordance with the question you asked or the wish you made.
Jiaobei is often used during important occasions, such as weddings, funerals or other major events, where people want to seek divine guidance or blessings from their ancestors or gods. It's a fun way to communicate with the spiritual world in order to find answers and follow the right path in life.
