He was betrayed at the beginning, from a cake seller to a wealthy person

Lu Yan did not go to Luji in the morning. She sewed a menstrual belt for herself at home with Mrs. Xu.

The menstrual belt is a long strip bag sewn with cloth. Two ropes at the front and back are responsible for tying it around the waist. Plant ash is stuffed in the middle. The plant ash is usually replaced, and then the menstrual belt is replaced.

You can't sell this kind of thing, you can only sew it yourself. Because the menstrual blood of women in ancient times was considered dirty. For example, the "Han Code" said, "You are not allowed to worship in the temple when you see your sister change." "Compendium of Materia Medica" also says: "When a woman enters the moon, her bad fluids are fishy and filthy, so a gentleman should stay away from them because they are unclean and can damage the yang and cause illness." This kind of shameful thing cannot be shown openly.

Lu Yan can actually understand that this stigmatization of menstrual blood may have originated from the ancients' fear of menstrual blood. The unknown brings fear. It is difficult for them to understand how someone could bleed for several days every month and not die for decades. This is so weird. There must be something weird here. Stay away! But how can a man be afraid of women, so they say this thing is bad luck and unlucky, giving themselves a reason to avoid it with confidence.

But understanding is understanding. This resulted in menstrual belts not being sold. Lu Yan found this matter difficult to deal with in her heart.

"It's so inconvenient that menstrual belts are not sold!" Lu Yan complained.

"How can such filthy things be sold?" Mrs. Xu said, "Even after washing and drying, they secretly dry them in their own house. How dare they put them out for sale?"

Lu Yan was obviously unconvinced: "Giving children is regarded as a woman's duty, carrying on the family line is an adult's obligation, and having many children and blessings is regarded as a blessing. In our era, fertility is extremely valued. But here comes Guishui Only women have the ability to give birth, so why is Guishui not celebrated but considered dirty?"

Xu was shocked: "What? Only women who come to Guishui can have children?"

Lu Yan was also shocked: "What? You don't know?"

The two looked at each other, and Xu said in a weak voice: "Now I know..."

Lu Yan: "..."

It's her fault, she has a modern brain, and many people in ancient times didn't know what she thought was common sense. In fact, many people in modern times may not know it either. Lu Yan was reading a book before and found that some women didn't know that peeing and menstruation were not the same thing until they gave birth. This shocked Lu Yan for a thousand years. It can be seen that there is indeed a big gap in people's cognitive level. This is true in modern society, let alone ancient times.

It was only after Lu Yan came that she felt the compression of women's living space. Menstrual belts had to be washed, but they couldn't be left to dry in the yard after washing. They were just like small clothes, they had to be aired secretly in their own rooms. Lu Yan knew that it was better to wash underwear every day and dry it in the sun instead of hiding it like a thief.

So Lu Yan resolutely called the masons and built a roofless hut with blue bricks in the courtyard, about three or four square meters. Two wooden poles were erected inside, and ropes were tied to the two wooden poles. This small room without a roof is specially used to dry menstrual belts and small clothes that cannot be hung outside. Lu Yan calls it the Sunshine Clothes Drying Room.

Mrs. Xu was stunned when she found out about this purpose! When Mr. Lu and Lu Sheng came back in the evening, they were also very confused about this roofless house. Xu said vaguely: "Yan'er thought that some things dried too slowly in the house, so she built a special place to dry things."

Boss Lu understood, suddenly understood and stopped asking. Lu Sheng didn't understand, and kept asking: "Drying things? Why dry in such a small place?"

"Stop asking." Boss Lu said to him.

"Why?" Lu Sheng didn't understand: "Why are you so mysterious?"

No one answered him, so he changed the question: "Why did you wash the sheets so late last night?"

Lu Yan: "..."

Xu: "..."

Boss Lu: "...shut up and stop asking."

Lu Yan felt that there was nothing to avoid about this kind of thing. Lu Sheng was just young and not stupid. He had never been exposed to this before when Xu avoided people, so he didn't understand it, but he would understand it sooner or later, so it wouldn't be a big deal to tell him now. But this is ancient times, and many things cannot be discussed on the table.

Lu Yan saw Lu Sheng open his mouth, but still didn't speak.

Lu Sheng felt aggrieved. He turned to look at Lu Yan. Lu Yan winked at him, so Lu Sheng calmed down and immersed himself in eating.

After dinner, Lu Yan went back to her room. Lu Sheng finished washing the dishes and hesitated for a moment before knocking on Lu Yan's door.

"Come in." Lu Yan called from inside the room.

Lu Sheng pushed the door open and walked in.

"Close the door." Lu Yan said again.

Lu Sheng's heart skipped a beat, and he hesitated and slowly closed the door.

"Do you have anything to say to me?" Lu Sheng asked.

"You want to ask me why I washed the sheets yesterday?" Lu Yan got straight to the point: "Because they were stained with blood and I had to wash them quickly."

Lu Sheng was shocked: "Stained by blood? Are you injured??? Let me see where you are injured?"

Lu Yan looked at Lu Sheng with a complicated face: "You don't understand at all!"

Lu Sheng was confused: "What should I know?"

Lu Yan: "Calm down, I'm not hurt."

Lu Sheng was even more confused: "Where did the blood come from?"

Lu Yan asked Lu Sheng, "Do you really want to know why the sheets are stained with blood?"

Lu Sheng nodded: "And what kind of riddles were you and your parents doing when you were having dinner?"

"Sit down." Lu Yan was sitting in front of the table. She raised her chin and pointed at another stool, motioning for Lu Sheng to sit down: "If you really want to listen, I will explain it to you in detail."

Sex education has been extremely lacking from ancient times to the present. There is still a biology class in modern times, but there was no such thing in ancient times. Men’s understanding of gender knowledge is only from erotic pictures and their own women, and their knowledge is also very shallow. Providing sex education to men of appropriate age is simply a thing that benefits the whole society.

Lu Sheng sat down at the table with a puzzled face, picked up the teacup on the table and took a sip.

Lu Yan: "Do you know how people are born?"

Lu Sheng choked on a mouthful of tea and coughed violently.

Lu Sheng coughed for a long time and finally calmed down. He still had lingering fears: "You are too detailed. How about you start from the beginning of Pangu's creation of the world?"

Lu Yan slapped the table: "Are you still listening?"

"Listen!" Lu Sheng immediately expressed his stance.

Lu Yan: "Do you know how people are born?

Lu Sheng said vaguely: "Isn't a person born when the yin and yang of a man and a woman intersect?"

Lu Yan was silent for a moment and continued: "The child is born by a woman, you know that, right?"

Lu Sheng nodded. Who doesn’t know this?
