Before giving birth, the bride's family should send food such as golden balls, meat, eggs, longan, walnuts, sugar and baby's clothing supplies. Rural areas often carry burdens, so they are called "raw burdens". As soon as I arrived at my daughter's house, I wrapped my clothes into a bundle and threw them into the bed of pregnant women through the window to predict that pregnant women would give birth to boys and girls in the direction of this bundle. Babies' clothes and saliva bags should be yellow, which is related to farmers' awareness of respecting the soil. According to the theory of Yin and Yang, yellow corresponds to the soil in the five elements, and it is in the five elements, so "soil is respected". Pregnant women want to eat, and their in-laws will give it to her, commonly known as "ear pregnancy."

According to medical needs, doctors implement some measures for pregnant women to achieve the process of making the fetus born ahead of time, which is called delivery. Professional acupuncture is actually a drug that accelerates uterine contraction.

"Fertility" is interpreted as "being forced to form the present state for some reason".

For example, under today's high housing prices, a large number of house slaves were born.
