What do you mean, six animals disappeared?

Hello: the divination term "things invisible to six animals" means:

Divination means losing livestock, but it is not necessarily a bad thing. In other words, this divination is in line with "a blessing in disguise, a blessing in disguise". The six animals here do not necessarily refer to "livestock" unilaterally, but can also be extended to certain losses, such as money and materials.

My humble opinion: The Book of Changes is where great wisdom lies, and divination is the fruit. We can't be happy, and we can't be trapped by fruits. Behind "happiness" is the interdependence of misfortune and happiness, and the premise of "sleepy" is to plan ahead.
