[Eight characters can't just be arranged in four columns, right? Can the column be divided into columns? Why? ]

The horoscope can only be arranged in four columns. Use these four pillars to tell fortune, because these four pillars represent yin and yang and five elements. The changing law of yin-yang and five elements is synchronous with the time change of year, month, day and time. But it is not synchronized with the two time units of minutes and seconds. Therefore, the yin-yang and five elements used for fortune telling cannot be divided into two columns.
