What is Nianzhu Yin Na? Does it matter? Is it a good thing that animals hurt each other?

Yin Na is a widely used method to predict the number of patterns. Its corresponding mathematical theory has been roughly defined by Yin Na in Sixty Jia Zi, and its basic meaning is expounded by "five elements-gold, wood, water, earth and fire".

Nianzhu is the year when a person was born in heavenly stems and earthly branches.

To hurt each other means to be victimized and killed, and it also means to resist each other. Of course, it is not good for the zodiac to hurt each other, and it is not good for the main marriage.
