"Miss Su, you don't mean to put the bristle in your mouth, do you?" Shopkeeper Fang thought about it and thought about it again and again, but he finally felt that it was not right. Even at the risk of offending Mr. Yue, he had to ask.

Not only shopkeeper Fang, but also Gu Chenzhong's eyes were red. "Miss Su, this bristle is not a clean thing. If you put it in your mouth, you may get sick."

It's not that shopkeeper Fang and Gu Chenzhong are ignorant, it's just that they don't know that any bacteria and viruses will be wiped out after being cooked at high temperature. What's more, there is no more suitable material for toothbrushes than bristles.

"Shopkeeper Fang, you can rest assured that before you make this bristle into a toothbrush, you have to steam it at high temperature for two hours before you can use it." Su Miaomiao turned to Gu Chenzhong and said, "shopkeeper Fang, this is a friend I introduced to you. In the future, he will provide bristles for toothbrushes."

It's the first time that shopkeeper Fang has seen this before, but it's a business with the Yue family. Since all the people who have a good relationship with Mr. Yue have spoken, he can't refuse to push the business out, can he?

"Well, since Miss Su is saying that, let me do the toothbrush business. Don't worry. I won't disappoint Mr. Yue." Shopkeeper Fang's timber shop has received a lot of orders. As long as the reputation of the Yue family is here, the business will surely come to us in an endless stream.

Seeing that shopkeeper Fang agreed, Su Miaomiao opened his mouth again: "shopkeeper Fang, I used to pay you five Wen for each toothbrush handle. Now I add the work of putting the bristles in. Now I give you ten Wen for each toothbrush handle. From the ten Wen, you should spare one Wen for each toothbrush you make and give it to Uncle Gu." Su Miaomiao's words fell, and Gu Chenzhong, who heard them, was shocked.

It's already obvious that shopkeeper Fang is not a fool. He can earn a lot more with such a job. He often accounts for it. Miss Su's offer is not low. Even if every toothbrush gives a penny to Gu Chenzhong, he still has a lot to earn. Thinking of this, shopkeeper Fang patted his thigh: "OK, let's make a decision, I'll write down the cooperation agreement with Yuejia another day. "

Gu Chenzhong was too excited to speak at this moment. He knew that Miss Su was taking care of him. The bristles were not in the village. After killing the pigs, they were just throwing things. He collected the bristles only by lifting his hand. He never thought that he could sell them for money. It was thanks to Miss Su.

"Shopkeeper Fang, uncle Gu sells pork in the vegetable market on the West Street. If you are short of bristles, let someone tell him in advance and ask him to send them to you." As long as the toothbrush began to sell in Dashun, Gu Chenzhong could take a few more liang of silver every day, which could be regarded as a thank-you to him for giving the firegun to her.

Without the blunderbuss he provided, Su Miaomiao would not have been able to find out the manufacturing method of blunderbuss. After all, the weapons of the 21st century are different from those of this time.

After manager Fang asked the housekeeper to collect the bristles, he sent Su Miaomiao and Gu Chenzhong to the door of the timber shop.

After su Miaomiao and Gu Chenzhong came out of the timber industry, they separated.

On the road just now, Su Miaomiao took some bristles from the sack and saw them. They were all old friends. Naturally, Gu Chenzhong would not fool her. The bristles were really the hairs on the pig's neck, which were much softer than the hairs on other parts.

When he got home, Su Miaomiao put the bristles on the fire and cooked them for two hours. He found a small dustpan and spread them flat on it. It was almost night before they were dried.

After the bristles were cleaned up, Su Miaomiao fixed the bristles with thin thread and stuffed them into the pores of the toothbrush handle. After the bristles were firm, he took the scissors to trim the bristles of the toothbrush. This simple toothbrush was made.

After dinner, Su Miaomiao went to the hospital again in his spare time.

There are a lot of patients in the hospital during this period. Su Miaomiao waited for a while, and then Gu Pinyan was free.

When Su Miaomiao told Gu Pinyan that she wanted to make a kind of tooth powder to brush her teeth, Gu Pinyan thought her idea was very novel.

At first, Su Miaomiao wanted to make toothbrush for tooth powder, just for the convenience of Xu. But now that she has done all of them, it's better to make a little money by using this idea. Some wealthy families in Dashun always gargle after dinner, and some even gargle with water soaked with petals, but the idea of cleaning teeth has not been formed from their consciousness, It's also important to keep your mouth clean.

Su Miaomiao remembers that in the 21st century, among the people she came into contact with, there were also manufacturers of dental powder. Most of those dental powder were made from heat clearing and detoxification Chinese herbal medicine, plus the particles of fine salt. Su Miaomiao told Gu Pinyan what she thought. Gu Pinyan immediately listed a list of heat clearing and detoxification Chinese herbal medicine.

There are many drugs for clearing away heat and detoxification, but these drugs must be suitable for all people. After two people's screening, we finally determined more than ten kinds of herbs.

After several disturbances, Chang'an Medical Museum has gained a great reputation in Wenxing county. Because of Ningyu pill and Shuluo pill, many people come to ask for medicine from Yuzhou government and other places. Now, all the medicines that are removed from the medical museum have their unique packaging.

The seal of Chang'an medical museum can't be forged. It was made to order by the craftsmen appointed by the government. There is only one seal in the world.

It is because of its unique seal that other medical schools are not good at pretending. Perhaps the crown prince inherited his own favor. A few days ago, Dashun promulgated a new law to punish those who falsely use other people's names according to the seriousness of the circumstances. This law has just been promulgated. I'm afraid no one dares to fight against Dashun's law. The more famous the medical school is, Su Miaomiao knows that this is the so-called brand effect in the 21st century.

It takes three days to make dental powder and prepare all the medicinal materials. Su Miaomiao lives in the hospital for three days. During the day, he works with Yin Feng and Wei Yao to help Gu Pinyan in his spare time.

Tooth powder seems to be made at the same time as the first batch of toothbrushes in the wood industry. The first batch of tooth powder was made into 100 small bottles, all of which were marked with the logo of Chang'an medical center.

The first batch of toothbrushes that Yuejia asked for was 10000, while only 1000 were left in Wenxing county. The rest were distributed to other Yuejia shops in Dashun.

Su Miaomiao also provided five bottles of tooth powder free of charge for every Yuejia shop that sold toothbrushes, so that people who bought toothbrushes in Yuejia shop could have a try.

Anyone who can go shopping in Yuejia shop has a rich family. The news that toothbrush and tooth powder were sold in Yuejia shop soon spread in Dashun. Su Miaomiao didn't know it. Later toothbrush and tooth powder became the most popular new year's products that year.
