After traveling through time, she took her husband to be a food doctor

After reading until midnight, Ding Xirui felt sleepy and yawned.

"Let's stop here today and go back to rest." Lin Mingxuan stood up and walked to the desk.

"I am indeed a little sleepy. But did you really memorize this book from beginning to end?"

"Correct."

"How about this? I'll list all the names of the herbs first, write them down on paper, and when you ask a question, pick one at random, and I'll recite the corresponding characteristics of that herb."

Ding Xirui directly turned "The Poem of Medicinal Properties" into a fill-in-the-blank question.

Lin Mingxuan thought for a while and said, "Okay. But it's not that simple. You can't confuse the four parts of 'cold, hot, warm, and neutral'. Also, I will ask the opposite question."

"understood."

In this way, the difficulty is reduced a lot. This book is originally a list of medicinal material characteristics, and there is no strong logical relationship. At her age, she can't just be an endorsement machine.

"Then I'll go back and rest."

"I'll take you there." Lin Mingxuan took out a cloak, wrapped Ding Xirui tightly in it, then held her shoulders and took her back to the bedroom.

"Thank you for your hard work today." After entering the house, Ding Xirui took off his cloak, stood on tiptoe, and put it on him.

"Take a rest." Lin Mingxuan tidied up the loose hair on her forehead, turned around and walked back to the study.

That night, all kinds of medicinal herbs came together, circling back and forth in Ding Xirui's dream like little birds. Seaweed, chrysanthemum, Trichosanthes, Phellodendron, and Cynomorium...

During the Great Snow season, Mr. Lin paced back and forth in the clinic.

"Dad, is the weather not very good at this time of year?" Lin Mingyuan asked.

"Yes, it's snowing heavily now, and it's still about the same as when Mingxuan just came back. At this time last year, I had already put on my jacket."

"Dad, don't worry too much. It's not the winter solstice yet." Lin Mingxuan advised.

"Look at how many patients we have admitted in the past few days. I am really worried." Mr. Lin sat down with a frown.

"Father, there are not too many patients, so don't worry too much. Besides, we have prepared the medicinal materials, and Xirui received a sum of money from Boss Zheng. We are fully prepared, so don't worry too much." Lin Mingxuan said.

"Father, is there anything else we can do right now?" Ding Xirui asked.

Mr. Lin thought for a moment and said, "The officials at Huimin Pharmacy should have noticed this situation. I wonder if they are prepared. I left work early today and will go there to ask about the situation. Go to the warehouse and check how much cotton cloth is left to cover the mouth and nose. If not, go to the market and buy some. Then, check if the big pot in the backyard for steaming clothes is still intact."

"Yes."

Ding Xirui and Lin Mingxuan went to the warehouse. Mingshi rummaged through several boxes and found the box containing the cotton cloth.

"I used it less in the past few years, so I put it inside." Akashi opened the box.

Ding Xirui picked it up and saw that it was a single-layer piece of cloth with a rope on the top that could be tied behind the head. This is a simple "mask" that will not be very effective if you really encounter a serious virus.

"Let's modify this mouth mask." said Ding Xirui.

"Madam, we use it every year. Is there any problem?"

"Yeah." Ding Xirui picked up one and put it on.

"If the evil qi is not serious, it's OK. But you see, the left and right sides and the bottom cannot be covered. If the patient coughs violently, the evil qi will enter the mouth and nose through these places, making it easy to be infected."

"Yeah, that's true." Mingshi nodded, and Lin Mingxuan also nodded.

"So what do we do?"

"First, add two more layers of cloth and sew the three layers together. If you feel stuffy, you can choose a less densely woven inner layer. Second, add a strap at the bottom to protect the mouth and nose more tightly."

"This is not easy to do." Akashi frowned, imagining what the modified mouth mask would look like.

"It's okay. The eldest young lady is familiar with a clothing store. We can ask the store for help." Ding Xirui patted Mingshi on the shoulder.

"Then we'll go right away. Thank you for checking the big pot." Lin Mingxuan said.

"Okay." Akashi said as he walked to the innermost part of the warehouse.

Several people explained the situation to Mr. Lin, drove a carriage to pick up Wen Yuexin, and then drove to the clothing store in the East Market. After listening to Wen Yuexin's explanation, the boss thought it was a profitable business, and immediately called two female workers from the backyard to sew the mouth cover according to Ding Xirui's requirements. The female workers were quick and nimble, and they sewed it quickly.

Ding Xirui picked one up to try on, and found that there were gaps on both sides of the mouth mask. He started to worry. At this time, there was no elastic band, and he couldn't sew it in to assist with adjustment. What should he do?

"Sister-in-law, how can the gaps on the left and right be smaller?"

"Madam, this is very simple. Just two stitches will do." After saying this, a sister-in-law picked up a mouth mask and sewed two more stitches on the straps. The gap indeed became much smaller.

"Or, you can do this." Another female worker folded the cotton cloth in the middle once, sewed it again, and after putting it on, the folds of the cotton cloth opened up, the left and right sides remained unchanged, and the gap became smaller. This really looks like the disposable masks of later generations.

Sure enough, the working people possess infinite wisdom.

"Sister-in-law, this is fine. You are so smart. Thank you very much." Ding Xirui became excited.

"Madam, how much do you want to make so that I can prepare it early?" The boss seized the opportunity and asked quickly.

Ding Xirui looked at Lin Mingxuan and asked him to make the decision.

"Please make three hundred first." Lin Mingxuan said.

"Three hundred." The boss felt it was a bit too little.

Ding Xirui thought for a moment and spoke:

"Five hundred then. Boss, how much do you need in total?"

"Cut the cloth, make the bandages, sew by hand, a mouth mask will cost at least two cents..."

"Boss, please don't brag. A piece of cotton cloth costs only two or three cents, and can make dozens of handkerchiefs. Now you charge two cents for a handkerchief, which is too much." Banxia said.

Ding Xirui retreated silently and pulled Wen Yuexin back as well, indicating to her that bargaining was Banxia's home ground.

"Girl, this is a three-story building. We can't do so much. Besides, you have to let me pay the sisters-in-law." said the boss.

"That can't be that expensive. How about this, five hundred hand towels for three hundred coins. If we need them in the future, we'll come back to buy them from you."

"Girl, you can't say that. Please at least let us earn some money. People in the backyard are waiting to eat."

"Then add another fifty cents, no more."

"Okay, girl. This is the lowest price. Please don't tell anyone else that our shop is not making any money." The boss looked bitter.

"Okay, don't worry." Banxia smiled. Since the boss agreed, there must be profit.

They smiled at each other and agreed to come back and get it in five days.

Wen Yuexin witnessed Banxia's bargaining skills for the first time and was deeply impressed. She asked Qingyun to ask Banxia for advice, and the two girls chattered all the way in the carriage.

"Next time you go out shopping, be sure to take us with you," said Wen Yuexin.

"Okay." Ding Xirui smiled.

Since the heavy snow, although the temperature was not as low as in the previous two years, the number of patients in the clinic did not increase much, and Mr. Lin felt a little relieved. When he saw the modified mouth covering towel, he was very surprised and praised it. He took some to Huimin Medical Bureau. Two days later, the owner of the clothing store received an order from Huimin Medical Bureau and was very happy.

That day, Ding Xirui went to An Yumo's house because the next day was Lin Mingxuan's birthday. After much thought, she decided to make a cake and then a hot pot. Unexpectedly, she met an "acquaintance" at An Yumo's house.

It was the girl I met when I came back from Qizhou City. Beside her was a girl named "Ahua".

"Xi Rui, let me introduce you. This is Miss Li, Yunru. Her family is in the kitchenware business. All the pots and pans in my restaurant are made by them."

"Yunru, this is my friend who grew up with me, Ding Xirui, she's married and is now Madam Lin."

Ding Xirui was excited and went forward to greet him.

"Hello, Miss Li."

"Hello, Madam Lin."

Li Yunru frowned slightly and asked, "Mrs. Lin looks very friendly. Have we met before?"

"I'm sorry to say that I accidentally offended Miss Li." Ding Xirui said embarrassedly.

"Huh? Have you two met?" An Yumo was very curious.

"A few days ago, when I came back from Qizhou City, I met Miss Li several times in an inn." Ding Xirui said.

Li Yunru remembered and blushed, and the atmosphere became a little awkward.

"We are all acquaintances now, so stop calling them Madam Lin or Miss Li. It sounds so distant." An Yumo said.

"Okay." The two responded.

"Let's go inside. It's cold here. Xiaoqin, take Banxia and Ahhua to have some snacks. I'll call you if there's anything else."

"Yes, ma'am."

The three little girls went to the backyard.

An Yumo walked to the table, asked the two to sit down, and said, "Xirui, Yunru is also worried about her marriage now."

Li Yunru sighed.

"Yunru, please tell me quickly. Xirui has a lot of ideas and maybe he can help you." An Yumo patted Li Yunru and motioned her to speak.

Li Yunru thought for a while and then spoke: "The last time I went to Qizhou City, I was visiting my grandmother. My parents also wanted to arrange a marriage between me and my cousin, but I didn't like that guy, so I had a fight with my mother and they didn't make it. But my uncle sent me a letter a few days ago, and my mother is very anxious. I don't know what to do."

After Li Yunru finished speaking, her eyes turned red. An Yumo walked over and patted her gently.

"My cousin listens to my uncle and aunt in everything. My mother saw that he was a scholar and was taking imperial examinations, and she wanted me to enjoy life with him in the future. I really can't believe that such a person can pass the imperial examinations and bring benefits to the people." Li Yunru became more and more angry as she spoke.

"But, I am the eldest daughter and my younger brother is still young. I don't have the heart to make my parents worry." Li Yunru lowered her head.

Ding Xirui felt sad and she was speechless.
