Did Yao tell anyone?

Liu Yi is one of the folk divination methods in China.

Six hexagrams hit the palm with three copper coins, making it roll irregularly in the palm, and its positive and negative sides appear to correspond to the yin and yang of six hexagrams.

Six hexagrams is the most traditional and simple divination method in the Book of Changes. Its changes are only divided into internal and external, each with three and six.

Six hexagrams, because of its changes, can know the past and break the future. Therefore, six hexagrams divination is the most commonly used divination method in the Book of Changes.

It's okay to tell others, but you need to pay attention to the way you tell others to ensure that their privacy will not be invaded.
