Toss a coin to tell fortune.

This is the algorithm of money divination.

It's old yin or. For example, if you use three coppers to calculate divination, you can take positive as positive. Both heads and one tail are positive, but they are still the same. The three fronts are both positive and negative. Shake it six times and draw a six-pointed star from bottom to top. Among them, all are positive or negative, that is, they become stubborn. If the number of hexagrams is less than three, use the first hexagram, the original hexagram, to break it. If there are more than three changes, we must turn the old yin into a new one, that is, change our mind and break it.

PS: Don't use any vernacular version, just use the most primitive ancient version to understand for yourself.

As for the concept of change of heart, I suggest you search online. Change of heart, comprehensive divination and wrong divination all have their own meanings.
