Before sexual intercourse, men and women wrap a red thread around their ears, then bypass the nasal cavity and wrap it around their necks; The red line should not be too thick, as long as a grain of rice is not as big as water. Grind half a dollar of milk vanilla, soak a glass of frankincense wine and drink it in one breath; Let the woman eat four or two cooked mutton first, take a bath every three to five days, or take a bath every half a month, and then have sex when the weather is fine. This means having sex, waiting for the woman's sexual excitement, and then tying a few three-inch hen feathers to the man's penis with red lines. When both men and women have bathed and are getting along gently, they will slowly insert the penis with hen feathers into the woman's vagina and push it forward one inch and two inches. Because both men and women have shallow sexual intercourse, the semen released by the man will soon enter the woman's body from the pores of the penis, which is called the sacred fetus. In this case, the baby born in pregnancy can not only live a long life, but also be healthy. Although there are cold and summer diseases, there is no harm. There is a poem that sings: If you want to know the gold in the water, go to the vagina of a beautiful woman of fifteen or sixteen; After more than a year of tenderness, you can have sex with her and collect the natural essence and blood gas in her body. Another poem sings: You can identify things at the peak of Huangya Fairy Mountain, and you won't get lost on the way to vagina and uterus; Feathers fly thousands of miles at both ends of the penis. After three reincarnation, this man with superb wisdom finally found the ladder to the outside of the cloud nine. Another poem sings: the dragon fell from the sky and the tiger surrendered. The long-closed porch cave is opened, the tiger is prancing, the dragon is moaning, and the jade tube is ready to welcome the birth of a new life. The breeze is blowing on the water, and golden waves are rippling on the water. The returning Jingxue only wants to live in a woman's womb.
