What are the ancient fortune-telling rules?

The ancients said that engagement depends on birthday. What does this mean?

Those of us who have seen some costume dramas know that people in ancient China used birthdays to tell their fortune. So what exactly is a birthday? In fact, a birthday is very simple, that is, the date when a person was born. But the ancients paid attention to heavenly stems and earthly branches, and they added some heavenly stems and earthly branches to the year, which formed their so-called birthday. As we all know, in ancient times, people were very adventurous. People think that the date of birth is closely related to people's fate, so they will decide their own fate through fortune telling.

Therefore, birthdays were very important in ancient China. People will judge whether their life is good or not according to their date of birth and their old age. Therefore, birthdays are very important in feudal society. In fact, besides the year, month and day, there are many complicated things about birthdays. In fact, most of us can't understand them. In other words, in ancient times, people had to know what their date of birth contained through fortune tellers. Therefore, in ancient times, when telling fortune or when two people are getting married, they should take out their birthdays to match.

Of course, in ancient times, birthdays were inconsistent. If two people's birthdays don't coincide, the two families will cancel the wedding, that is, they will cancel an engagement. People still believe in fate, that is, the date of birth contains many truths. According to the date of birth, they can infer their own lives. In fact, birthdays are no longer practical for us. We know that in a society, we can't live by risk alone, which means feudalism can't play an important role in our life.

Therefore, we don't need such things as birthdays now. I think ancient China people were still too feudal. They combine their fate with their date of birth. I think it is very unreasonable. Now this unreasonable thing has long been abandoned by our present life and modern people.
