On the table of the Qing dynasty, a man and a woman were pregnant in May of the lunar calendar on 20 18.

At present, there are not many families who use the palace table of Qing Dynasty to calculate the birth of boys and girls, and most people don't know much about this calculation method. In ancient times, this method was very popular and sought after by many ordinary people. Let's take a look at how the Qing Palace Watch calculates the number of boys and girls.

1, the origin of the Qing dynasty watch

The Qing Palace Table is a table summarized by the imperial doctors in Qing Dynasty according to their own experience and the probability of female fertility. In the past, such forms were specially provided for emperors, queens and princes, and it was said that the accuracy rate was as high as 90%. It contains the knowledge of Yin and Yang five lines of gossip, plus the calculation of time, and finally made the Qing dynasty table that we see now.

2. Calculation formula for clearing the table

In the calculation formula of clearing the table, the imaginary age of pregnant mother and the lunar month of pregnancy are very important. To put it simply, it is necessary to add the pregnant mother's lunar birthday month to the pregnant lunar month, then subtract the imaginary age and add 19. If the mantissa is singular, it means that pregnant women will give birth to boys; if the mantissa is even, it means that pregnant women will give birth to daughters.

3, calculation points

In the process of using the Qing dynasty palace table to calculate, we can find that all months are lunar months, which are calculated according to the imaginary age of pregnant mothers and the lunar months of pregnancy, so these two figures are not allowed to be mistaken. Most importantly, if you encounter a leap month, you should pay attention to the fact that the first half of the month is included in the last month and the second half is included in the next month.
