On the basis of traditional numerology, Li Hanchen created many new prediction theories, and tested and revised these theories through years of practice, thus completing a new numerology prediction system. Li Hanchen believes that the five-element changes caused by celestial movement in the solar system can be reflected by the law of heavenly stems and earthly branches action, and the rise and fall of people living in the solar system will also be affected by the five-element changes, so we can use heavenly stems and earthly branches to infer the ups and downs of people's fate. Its new theoretical system of Zhouyi, represented by "Five Theories", has opened up a new realm of eight-character prediction and solved many problems that traditional numerology prediction can't solve, which is refreshing.
