The eight-character sun column refers to heavenly stems and earthly branches on the day of birth, which can also be said to be the fifth and sixth words in the birth. The eight characters are four groups of branches calculated according to the time of birth (year, month and day), namely, the annual column, the moon column, the sun column and the time column. So the eight characters are also called four pillars.
It should be noted that from the perspective of the horoscope, it is very important that the heavenly stems (Geng) of the Japanese column represent the life of the host, sometimes called Japanese yen and Japanese Lord, and the earthly branches of the Japanese column represent the life of the spouse.
The Modern Expression of Sunzhu
But in modern times, influenced by the western calendar, some numerologists have new views on the starting and ending points of the sun column. They think that a new day should not start with children, but should start with children. For example, Mr. Yuan Shushan, a famous numerologist in modern times, discussed this issue in his famous book The Origin of Numerology. Yuan believes that the sun column is still calculated according to the daytime after the early night and before the early morning. Yuan's statement had a great influence in modern times, and it is still used by some numerologists.
