First, the ancients were superstitious. They thought that if the eight characters didn't match, they wouldn't live for a lifetime, and they could only continue if they were true.
When the ancients fell in love or got married, they all hoped that all shall be well that ends well, so before falling in love or getting married, they all wanted birthdates from both sides to get together, and then found a Taoist to see if two people had the fate of husband and wife. If the eight characters of two people are very consistent, then two people can go to the step of talking about marriage. If the birthdays of two people are different, it means that there is no husband and wife and they can only break up.
Second, the official fortune is related to the eight characters. If they get along well, it's a godsend.
When watching costume TV series, the ancients paid more attention to official luck or fortune, so before getting married or falling in love, we must first see whether the other person's eight characters can prosper. If the two words match and have a good meaning, men will generally love this woman more. If the eight characters indicate bad luck together, it's time for couples to break up. Although these things have no scientific basis, the ancients recorded them in detail!
Third, the most important thing to look at a birthday is to know if the other person is a disaster, because it is not worth falling in love and then putting your life into it.
In fact, looking at the eight characters depends not only on whether the two sides are consistent, but also on whether the other side is their own disaster. If two people collide, they will kill each other because of one character. Do you think they will still be together? Even if they fall in love again, they will choose to break up. After all, love is not important, so don't underestimate the calculation of eight characters. In ancient times, many people could not be together because of this unscientific thing.
