What does the word "seeking heirs" mean in the old almanac?

1. To seek an heir is to seek an heir (offspring) from the gods. That is begging for children.

2. Seeking an heir comes from the ninth volume of "Women's Full Prescription". It means to have a son or daughter, and it also means to get married and have children. In today's era of advanced medicine, many people will choose an auspicious day when they choose to have a maternity.
