Others help me read the eight characters and say that I am bigamy. Do people who take a second marriage have to divorce?

It may not be 100%, but there is information about the second marriage in the eight characters. Let's just say that there will be two marriages under normal circumstances. The reason why it is not 100% is not that fortune-telling is not accurate, nor that numerology is unpredictable, but that everyone has different degrees of human choice and good and evil.

Destiny is doomed at 7 points, the day after tomorrow is artificially selected at 3 points, and the day after tomorrow is doomed at 7 points. It means that everyone is influenced by his eight-character luck, and he can only be destined to know a certain range, a certain circle and a certain level of objects, which is destined to be good. In this doomed circle, the choice between good and bad is artificially chosen at 3 o'clock the day after tomorrow. For example, when a person is lucky and has three objects to choose from at the same time, one of them is to disagree completely. At this time, the quality of life and marriage of married couples will be very different. Therefore, we can neither think that fate is doomed by 100% nor that fate can be changed by 100%. There are both doomed choices and acquired choices.

A person who does good deeds and accumulates virtue, if his fortune is high, will naturally be rewarded and is destined to get married twice. Because of his high wealth, he will get married once. Since ancient times, good has been rewarded with good, and evil with evil.
