Wei Zi's fortune-telling is an astrology and one of the traditional numerology in China. It is believed that the astrology at birth determines a person's life, that is, fate. People think that all kinds of stars and obsidians have a specific relationship with people's fate, and because stars and obsidians appear in a certain order, the corresponding people accept their influence in this order. By analyzing the astrology at birth, we can judge the fate and time sequence of people themselves. Because in this astrological analysis system, purple MSI is the first of all stars, so the operation is called' purple infighting'.
