Ask the master of Yi Studies. What is a person's life like? It depends on which phase of the eight characters. How to analyze it?
First of all, the Book of Changes you mentioned should refer to the knowledge of the Book of Changes, which is the first of China's classic works and a book of great wisdom. I suggest reading The Book of Changes and Life by Mr. Fu Peirong. Then there are eight characters, the first six words are the main branches of the year, month and day when the person was born, and then the last two words are obtained by combining the time with the first six words. This is what is often said. How to analyze it is a long story. You can buy a book first if you are interested.
