Another text, Health Benefits of the Bedchamber, indicates that certain times were better for intercourse than others. A person had to avoid having intercourse on quarter or full moons and on days when there were great winds, rain, fog, cold or heat, thunder, lightning, darkness over heaven and earth, solar and lunar eclipses, rainbows and earthquakes. Having intercourse at these times would harm a man's spirit and would cause women to become ill. Children conceived at these times would be mad, stupid, perverse or foolish; mute, deaf, crippled or blind; unfilial and violent.
Also important was selecting the right day for intercourse if a person desired children. After the woman's period, the first, third or fifth days were the best. If on these days the man ejaculated after midnight, the child would likely be male. If a female child was desired, the man needed to ejaculate on the second, fourth or sixth days after the cessation of the woman's period.
The location of sex was also important. People had to avoid the glare of the sun, moon or stars, the interior of shrines, proximity to temples, wells, stoves and privies, and the vicinity of graves or coffins.
If these suggestions were followed the family's offspring would be good, wise and virtuous. If they were not followed, the offspring would be evil and the family would eventually die off.[17]
