What does the change of heart mean in copper coin divination?

In fact, the fifth step is that if the result obtained in front is a word, it is yin, which is represented by a dotted line "-"; And if it is a word with two backs, it is Yang, which is represented by a continuous line "-". In both cases, there will be no change of heart.

However, if there are three words, it is Lao Yang, which means "Yang Yao". And if it's three backs, it's old yin, and it's going to become yang.

Do you understand?

As for what you said, I guess it was a technical mistake.
