Why isn't there a word in the Stone Pillar?

The word "time column" is not due to the two branches of a certain ten-day period, that is to say, the time has not yet arrived, so although the word seems to exist, it can't really play a role. The eight-character column is empty, which means that after 49 years old, it is more difficult to get tired, lonely in old age, thin children, few children, or more girls, and the body is lonely and sleepy. It also represents the unsatisfactory situation in career, family, interpersonal relationship and the handling between children and grandchildren, students, subordinates and employees in this life, which does not help each other much. This answer is for reference only. Don't be blindly superstitious.
