Xiao Yun then completely understood. He once saw it in a miscellaneous book in later generations. It was said that in ancient times, before Cai Lun invented papermaking, women used to put wood ash into small cloth strips, tied with thin threads at both ends to their waists, forming the so-called sanitary belt. The number of replacement strips is determined based on the degree of wealth. The sanitary belt is replaced, and the sanitary belt is poured out, and the sanitary belt is washed with clean water, soap and kale, etc., and then used after air drying, and when urgent, they are roasted on fire. At this time, it is basically done under private conditions.

Of course, some wealthy families will prepare clean cotton and other items for women as materials for making sanitary belts. However, since new cotton is not easy to absorb water, many women are more likely to accept wood ash.

After Cai Lun invented papermaking in the Eastern Han Dynasty, due to the low cost of paper, it began to gradually promote it. It greatly accelerated the process of human civilization and also changed the physiology of women. Grass paper is easy to absorb moisture. It is much cleaner and hygienic than the wood ash. In addition to the low price of paper, many people use straw paper or use straw paper in sanitary belts. Some wealthy families use white paper for sacrificial sanitary belts, because in addition to being tough, this white paper is also whiter and relatively hygienic. However, because this kind of paper is expensive, not all families can afford it.

In terms of female physiological hygiene, only wealthy families in the past were paid attention to. Women have always been in a relatively low position in social life. Many people, girls try to solve their difficulties during menstruation. Some girls will use cotton and other items as plugs and stuff them into the yin channel to try to prevent the outflow of blood, while some girls have never used sanitary belts for life.

In ancient times, it was not as open as in the 21st century. All kinds of sanitary napkins and sanitary balls could be sold. At that time, there were very few sanitary belts sold in the market, and they were only sold by peddlers or some rouge and dough shops. So basically, the sanitary belts used by women were made by themselves. Women would pass the old to the young, and the big to the small to learn the techniques and techniques of making sanitary belts. Some skillful women would embroider patterns on the sanitary belts.

The sanitary belt used by women shall determine the frequency and number of new items based on the conditions of their family. Some women shall accompany each sanitary belt for life.

"Bad man, what's wrong with you?" Seeing that Xiao Yun didn't speak for a long time, Xiao Yue said with a blushing face.

"Remember some things?" Xiao Yun pinched her face, and suddenly remembered the sanitary napkins of later generations in his mind, and thought to himself: "These sanitary napkins of later generations are not only disposable, but are leak-proof. They are not only hygienic, but also convenient. If you can help with some modification, it is not impossible?"

"Is there anything else except rice paper and wood ash?" Xiao Yun shook his head and said.

It was his husband, and the three of them were a little shy at first. After seeing that, Xiao Yun had no sneer at all. The shyness just now went away. After hearing his question, Xiaoyue blushed and said, "In addition to rice paper, she also needs leaves, wood ash, and cotton. But the effect of cotton and leaves is not very good, the best rice paper, but I can't afford such expensive things. Just use some wood ash and tie it in a sanitary belt, which is easy to use. It can be wrapped around the body like a cloth, which is always inconvenient, and it is very troublesome to clean it up..."

Xiao Yun thought for a while and said, "Is there a way to help you solve this problem?"

Fang Taiping, Su Erxiao and Xiaoyue looked at each other and looked at Xiao Yun with incredible eyes. No wonder, in ancient times, the idea was not so open. Most men did not pay attention to women's health at all, and were even more said to be concerned about hygiene belts. Most men think that women's hygiene belts are evil and dirty symbols. They are very taboo to see women's hygiene belts. I think Xiao Yun was the first to discuss face to face with them, so they had to let the three of them look at him with strange eyes.

"Do you really know?" Fang Taiping said. During the few days of each month, she always put the wood ash into small cloth strips, tied with thin threads on her waist, forming the so-called sanitary belt. Not only is it inconvenient to walk, but she is also worried that it will not be tight enough and fall off. This is not counting. She also needs to replace it every day, pour out the sanitary belt that is sucked in water and soapy gua, etc. to remove the sanitary belt. After air drying, it is misunderstood and shameful. Every time she gets frustrated, she has a headache. At this time, she heard Xiao Yun say that there is a way to help them get rid of this trouble. Although she doesn't believe it, she can't help but get curious when she sees his confidence.

Xiao Yun smiled and said, "Of course it's true. You can wrap clean cotton fibers and highly absorbent pulp with a fine and soft cloth, make it into a long strip of cotton pads, and then make it into a rectangle. In this way, the weight is light, there is no need to worry about falling off, and it also effectively reduces the pain and inconvenience of menstruation. Isn't it great?"

"Is this OK?" Fang Taiping asked hesitantly.

Xiao Yun smiled and said, "Of course it's OK. Who is your husband? Don't you believe it?"

"I haven't heard of this method. Is it useful? Then I'll try it back." Su Erxiao, Xiaoyue thought for a while, and Su Erxiao said with a blushing face.

Xiao Yun said: "Of course it works. I'll make some for you later, so that you can try it next time and keep it practical!" After saying that, he walked over to Fang Taiping, reached out and put his hand around her slim waist, gently stroked her lower abdomen with his big hand a few times, and smiled and said: "Look, I don't want this wood ash and rice paper. I'll leave it to me in the future. I will give you something better than this?"

Fang Taiping looked at him for a while, suddenly stretched out his arms, entered his arms, buried his hot little face in his arms, and said in tears: "Bad man, you are so kind to us, we will never be separated for the rest of our lives! Otherwise, I would rather die than live alone?"

Xiao Yun smiled and hugged the person in his arms hard, and cursed: "Silly girl, how can the bad guy be willing to separate from you? Don't forget, you are the little care of the bad guy, little baby, little cutie? Without you, who will push the cart with me?"

"Ah--bad guy, I'm so necrotic?" Fang Taiping's pretty face was blushing. Even Su Erxiao, Xiaoyue's face was hot.
