Yuan Hai Zi Ping is a numerology book written by Xu Sheng in Song Dynasty according to the method of approving longevity by Xu Ziping, a famous numerologist at that time. This book discusses the "four-pillar fortune-telling method" completely and systematically for the first time. It can be said that it is the masterpiece of China's ancient numerology, and it is highly praised by people who study numerology in later generations. The greatest contribution to numerology is to further develop the method of calculating the five elements of year, month and day founded by Li in Tang Dynasty into four-column numerology. The four pillars are the year, the month, the day and the hour, all of which are eight characters, so the four-pillar fortune-telling method is also called the eight-character fortune-telling method. Each of these eight words contains some five elements. According to the principle of the change of Yin-Yang and Five Elements, people's fate can be inferred.
There is no one who does not look at Yuan Haiziping when learning eight characters. Look at this and you'll see if the old and the new are bullshit.
Yuan Haiziping began in the Song Dynasty, and the real four-column prediction began with this book. Before that, there was a three-column forecast. What is the pattern?
