The whole family travels through time and space, and the three of them struggle together

After several days of hard work, Carpenter Tian finally made several wooden handles similar to toothbrushes, and the fine holes were also processed.

Zhou Dajiang also found the material for making toothbrush bristles, goat hair.

The reason was simple: he himself could not accept pig bristles, and horsetail hair was too difficult to obtain. It happened that there were sheep farmers in the village, and the wool could be regenerated after shearing. Moreover, the wool of a sheep could be used to make many toothbrushes. As long as the sterilization was done properly, it was completely feasible.

He thought and did it. The sheep farmer's surname was Gao, and people called him "Gao Danian" because he was born on the first day of the Lunar New Year.

Gao Danian raised sheep mainly for meat. When he heard Zhou Dajiang wanted to buy wool, he was so happy that his mouth was pulled up to his ears. He quickly called his wife: "Mother, take out some of the wool you saved earlier."

Mrs. Gao is a careful person. She collected all the loose wool dropped by the sheep, thinking that she could add it to the cotton shoes for her children to keep them warm. She didn't expect that she could even sell it for money.

She found a large bag and said, "It's all here. It's not good stuff. My dad used to sell cold noodles at your house, and we made a lot of money. I'm giving this wool to you for free."

How could Zhou Dajiang take other people's wool for free? Finally, under Zhou Dajiang's insistence, he bought it for thirty cents a bag.

After getting the wool, Zhou Dajiang asked Chen Xiuying to take some time to process it.

Chen Xiuying is very busy now. The construction of Zhou Dahe's house has also begun. Li asked her and Zhang to help with cooking, and she readily agreed. There are guests at home and she has to take care of them. She has to cook six times a day. How can she not be busy?

She chose a sunny but windless day, washed the wool clean, picked out the debris, exposed it to the sun for a while, then steamed it in a pot for quarter of an hour. After steaming, she exposed it to the sun for another day before collecting it and handing it over to Zhou Dajiang.

After Zhou Dajiang got the toothbrush handle made by Tian the carpenter, he cut off a piece of the fine hole part of the toothbrush head from the top, and opened a triangular groove on both sides of the cut part. Then he glued the cut part and the wood chips cut from the groove together, and asked Zhou Sisi to draw two drawings according to the shape. He marked the size of this part with a ruler. This is the plug part of the toothbrush, and the size must be exact.

He then carved four grooves into the fine hole part of the cut surface, and asked Zhou Sisi to draw the cross section of the grooves. He marked the depth of the grooves on the drawing.

The rest was easy. Zhou Dajiang took a small bunch of wool, tied the front end of the wool with a thread, passed it through the small hole from the groove surface, and then used the same method to pass the other end of the wool through the adjacent small hole. After passing through all the small holes, he cut off the thin thread and the grown wool.

The rest is to press the toothbrush plug in. The reason for pressing instead of gluing is that the toothbrush is exposed to water every day, and the fish bladder glue opens with hot water. In addition, the size of the plug is just right. Manual installation is tight, so it is better to press it in.

He decided to find professionals to do professional things, so he went to the factory and asked Carpenter Tian to make the toothbrush plug according to the drawings.

Then, he gave Zhou Dahe a drawing of a toothbrush and a plug, and asked him to make a fixed mold for each part, install it on the stamping machine, and insert the plug vertically into the toothbrush head.

He could design the fixed mold himself, but he couldn't stay in the factory all the time, so he took this opportunity to let his third brother practice.

Fortunately, Zhou Dajiang was not disappointed. He spent three days making a set of molds by himself, installed them on the stamping machine, and successfully pressed the newly made plug in.

In order to make it more beautiful, Carpenter Tian applied a layer of bright varnish to the surface of the toothbrush handle, and the first toothbrush was made.

Zhou Sisi took the toothbrush and tried it out. Although it still had some imperfections compared to modern toothbrushes, it was much better than the willow branch. She happily said to Zhou Dajiang, "Dad, this toothbrush is really useful! We can make more and sell them to others."

Zhou Dajiang nodded. He thought so too. Otherwise, why would he spend so much effort preparing the drawings and asking Zhou Dahe to make the fixed mold?

The toothbrush handle is made of wood, and wool is also very cheap. Although the mold is a bit expensive, if it is spread evenly over each toothbrush, it is not that much. The rest is the labor time for handling and processing the wool.

What's the cheapest these days? Labor is the cheapest. So, the cost of a toothbrush is only a few dozen cents, and ordinary people can afford it. Moreover, toothbrushes are consumables, which means that the market can have an annual output of tens of thousands or even hundreds of thousands of toothbrushes!

Zhou Dajiang didn't need to arrange the rest of the operations, and the processing plants all started moving.

First, Xue Ren bought the wool processed by Zhou Dajiang. Xue Jin quickly arranged for people to process 100 pieces, sent 50 pieces to the Beijing headquarters to explain the situation, and allowed internal employees to purchase the remaining 50 pieces at a low price for product testing.

While others were still observing this good opportunity, Zhou Dajiang decisively bought twenty of them. There was no other way, with so many people in his family, he had to stock up on some for backup.

Seeing that Zhou Dajiang bought so many, Zhou Dahe and Zhou Dahai also bought one for each of their family members.

Brothers Xue Jin and Xue Ren, Ma Lin, Tian Youcai and Zhang Dazhuang also bought one each for themselves and their families, and the remaining few were bought by Zhou Dajiang.

Zhou Dajiang thought, now I can stock up, my wife will definitely praise me for being so capable when I get home! He hadn't seen how fiercely everyone rushed to buy goods during the Double 11 shopping festival in modern times. While people in ancient times hadn't realized this yet, he decided to grab some first.

Sure enough, when he returned with more than twenty toothbrushes, he was warmly welcomed by Chen Xiuying and Zhou Sisi.

Zhou Sisi took a toothbrush and gave one to every member of the family, including Mrs. Cheng who was temporarily staying there and her maid.

Since coming here, Mrs. Cheng has made new discoveries every day, from the room decoration, new food, the children's small classroom, Zhou Sisi's paintings, to the elder sister's doll workshop, and now she has a new toothbrush for brushing her teeth. She feels that every day is very interesting and she wishes she could move her home here.

The autumn wind is bleak and the weather is cold, and the grass and trees are shaken and dew into frost.

Ten days after the Frost Descent, on the agreed delivery date, Zhou Dajiang went to the provincial capital again with the finished wire rings and punchers, and Mrs. Cheng also left Qingshangou reluctantly.

Also traveling with them were Chen's mother and Zhou Sisi. Chen's mother brought dolls and picture albums to deliver the goods, while Zhou Sisi was just there to play.

According to her, people need a balance between work and rest. During this period, she not only completed the first three issues of "Calabash Brothers", but also completed the middle and lower volumes of "The Kingdom of Strange Animals". Having exceeded the target, she must reward herself and take a walk to relax!
