Look at marriage. Can you talk nonsense about your age on your birthday?
Of course not. Birthday, or eight characters, is another way of saying the four pillars of Zhouyi. When people use "heavenly stem" and "earthly branch" to represent year, month, day and hour respectively, such as Jiazi Year, Shen Bingyue, Guichou Day and Renyin Time, it contains the basic state of celestial movement when a person is born. There are two words in each column and eight characters in four columns, so fortune telling is also called "measuring eight characters" It is inaccurate to say that age is equivalent to false information.
