Chapter 216: Take More Care of Young People From Poor Families

When Li Yi was making soap, during the saponification reaction, there were layers of salt, glycerin, etc. during the chemical reaction.

There is an unsaturated saponification reaction liquid inside. The salt and glycerol are extracted separately, and the rest is soapy water.

This soapy water is generally used to participate in the next saponification reaction. If you want to purify it, some soap will still come out, but the input and output are not proportional.

Now it happens to be sold, and Li Yi can't care about it in the entire Tang Dynasty. There is still no problem in Chang'an County.

There are more than one million people, and not all of them use soapy water or soap powder. The poor people use plant ash to scrub.

That is to say, people in the Tang Dynasty do not take a bath for a long time, especially in winter. Only officials have a day off to take a bath.

As for who always takes a shower, it’s not unusual for the girls in Pingkangfang and Beiqu to take showers eight times a day.

In addition, there are villagers who do hard work and special workshops in Zhuangzi. They have their hair cut, short hair, even hairless for men.

When you get to the bathtub, wash yourself vigorously, which is convenient and comfortable.

If Li Yi hadn't taken care of his face, he would have wished he had shaved off his bald head. It is convenient to perform surgery on a bald head. Just wash it off and put on a surgical cap, so you don't have to worry about anything falling into the patient's wound.

"Oil is hard to find, especially pancreatic juice. Others use it to wash things with plant ashes." Li Chengqi knew that Li Yi had used a lot of fat before.

"I use soybean oil now." Li Yi whispered, who stipulated that the saponification reaction must be animal fat?

"Soybean oil can also be used?" Li Chengqi was surprised. He had never learned to use soybean oil to make soap since he was a child. How many magical things are there?

Oil and soap, there are a lot of differences between the two things, right?

"It's like making soy milk into tofu." Li Yi understood his elder brother's thoughts and explained with the simplest example.

"Yes, soy milk can be made into tofu and dried tofu. For soap, gypsum, brine or vinegar is added to soybean oil?" Li Chengqi began to imagine.

"If you add vinegar, the cooked oil can be used to mix vegetables." Li Yi joked.

After speaking, Li Yi asked the child who came over holding his stomach: "What's wrong with you?"

"Belly, belly," said the child.

"Is there a bug? Brother Yi, give him that candy." Li Chengqi felt that he could also be a doctor.

Li Yi asked Qingsong to level the box, put the child on it, and started to press it.

"Does it hurt here?" Li Yi asked.

"It hurts a little when you press it, but it won't hurt if you don't press it," the child replied.

"Why does it hurt? Is it like a needle prick?" Li Yi asked again.

"It just hurts when I press it. It hurts wherever I press it."

"What about here?"

"It doesn't hurt, I can't help anymore, I want to spit out." The child said and started to struggle, wow! Spit.

"Can I still vomit again?" Li Yi asked looking at the 'water' vomited out.

"I can't spit it out." The child replied.

"Give him two skewers to eat, if he's hungry," Li Yi ordered.

Then ask the child: "Didn't you eat last night?"

"How do you know?" The child said I was surprised.

"Not only did I not eat, but I also didn't drink a few sips of water. When I got up in the morning, I went straight to Zhuangzi and drank a few sips of soup. My body needs a lot and you exercised a lot on the skateboard.

Metabolism is too fast, and water quickly enters the kidneys and bladder.

The remaining bit of meat foam will give feedback to the stomach, and gastric acid secretion will increase, resulting in vomiting with foam.

It's still a bit bitter, right? Gallbladder is secreted, and there is bile in it. Gastric acid irritates the gastric mucosa, and of course you will have a stomachache. "

Li Yi gave a scientific explanation, what kind of insect? Just hungry.

The farmer next to him gave some skewers, which the children ate deliciously.

"Does it still hurt?" Li Yi asked again at this time.

"It doesn't hurt anymore, it feels warm." The child said honestly.

Li Chengqi was stunned beside him. He didn't think there was anything wrong with being hungry. He was shocked by Li Yi's diagnosis.

Just press it and the child will vomit, and you will know that he is hungry. Can you tell even if he did not eat last night?

"Who else is hungry and comes here to eat? Eat less. If there is lunch at noon, can I, the Li Family Village, give the children a bite to eat?"

Li Yi shouted to the other children.

Sure enough, many children came back and wanted to eat.

"Is it because you don't eat?" Li Chengqi wanted to learn, but the miracle doctor didn't take it seriously.

"It's soup. If you don't drink soup, you'll be fine. There is oil and water in the soup, and the stomach will naturally absorb it. Otherwise, if you are too hungry, your stomach will find itself empty and slow down the secretion of gastric acid, so you won't feel hungry anymore."

Li Yi explained the reason: hunger is the feedback of gastric acid irritating the gastric mucosa.

If you drink a lot of water and feel less hungry for a while, it is because the water dilutes the stomach acid.

Li Chengqi: "..."

He felt that he was not suitable to study medicine, at least not suitable to study medicine with Yi Di. It was too difficult. What nonsense?

"What now?" he asked.

"Now eat a few skewers to combine the gastric acid, and then the gastric acid will be secreted more. By noon, you can eat a lot of food, which is different from ordinary adults who eat less."

Li Yi said that he also scooped up a spoonful of soup and drank it. It was cold outside.

"Yes, I am a poor man who lives in poverty." Li Chengqi said a common saying.

"Boss Li, do we eat for free?" A man from a wealthy family came over and said to Li Yi.

"Are you sorry?" Li Chengqi shot back.

After saying this, Li Chengqi left in a hurry. The game over there should be over, right? It's time for the next show and then dinner.

Li Yi also did not answer such boring questions and continued to check on the child's physical condition.

Watching it is a learning process, and sometimes I feel my pulse and make comparisons.

During lunch time, children from wealthy families went to Zhangjia Village, and those who came on their own were arranged in a corner of the cafeteria, where each person had a portion of Mushu Pork Rice Bowl with shredded radish soup.

The children laughed, UU reading www.uｕkanshu. net They think there is only one bowl of noodles, and a bowl of noodles is good.

It turned out that there were meat, eggs, fungus and cucumber slices, and the shredded radish soup was delicious.

So they decided to come back tomorrow and call other friends.

"Proprietor, they will definitely come tomorrow." Ziyu said words that were in line with human nature.

"I'll give them twice-cooked pork tomorrow. I'll make it with garlic sprouts and no chili. I don't have chili for others to eat."

Li Yi agreed with Ziyu's words and told him about tomorrow's dietary arrangements.

"Proprietor, I mean they are greedy." Ziyu regarded herself as a member of Zhuangzi and felt sorry for giving things to others for nothing.

"I didn't dare to give them fat meat today because they were afraid that their gastrointestinal tract would not adapt to it if they didn't eat oil for a long time. Mushu pork is just the right adjustment. Tomorrow they will eat fat and lean twice-cooked pork, plus garlic sprouts to stimulate the gastrointestinal tract. The day after tomorrow, they will eat braised pork belly. meal."

Li Yi continued to talk as if he didn't understand or didn't hear what Ziyu said.

"Master, I've finished eating. I'm going to take over from Taohong to take care of the baby." Cuiliu put down her chopsticks and said, "Go out."

"I've finished eating too." Brown Yan took the last bite of food into his mouth and said in a vague voice, but he hadn't swallowed it yet.

"Proprietor, I'll tell them later." Qingsong took the initiative to take on the important task of telling the four people about Zhuangzi's situation.

"Selling newspapers requires manpower. If you don't take good care of yourself, how can you go to various places to deliver newspapers." Li Yi said something that the four newcomers did not understand.

His movable type has been produced, copper movable type.

Movable lead type is difficult to take care of in the winter and can be easily poisoned, so I haven't touched it. I will replace it when the weather is warmer and more protective measures are in place.

Each movable type is money, made by melting copper coins and ordinary copper utensils.
