Dean Zi stood on the podium, lifted his glasses, and said, "Before starting the class, I will ask a few small questions at random, just to liven up the atmosphere and let everyone get to know each other. ”

She picked up the training list and added, "I say a color, and the colleague who is named stands up and says what the tonic does." Dark blue, blue screen colleague to answer. Dean Zi began to roll call.

"Dark blue is an adult trace element supplement. Lan Screener's colleague replied.

"What are the effects, and what are the precautions for taking it?" Dean Zi asked again.

"Adult trace element supplements are mainly used to supplement various trace elements in adults. If you eat a portion of salt normally, you can supplement it once a year or so. If you don't usually take salt supplements, it will take about four to five months to replenish them. Lan Screener's colleague replied.

"Well, that's right. ”

Dean Zi nodded, looking quite satisfied. In fact, these are basic common sense for their doctors, and there is no difficulty.

"Too much salt and other condiments are not good for our body. Just try it once in a while. The health of our body still depends on dark blue adult trace element supplements. Dean Zi said coldly.

"Yes, according to the recommendations of our general meeting of the National Health Management Committee, it is relatively healthy for each adult to consume less than five grams of salt per year. Lan Screener added.

"Too much taste stimulation is not conducive to our physical health, and blindly pursuing delicious food is an uncontrolled performance of life and immoral. Alright, let's move on. Dean Zi said with a straight face.

"Five grams per person per year? Promi thought to herself.

Although in the original world, he never paid much attention to the amount of salt consumed, but according to his memory, when he was a child, at home, a bag of salt was almost eaten in less than a month. The dosage is definitely much higher than this standard. If everyone is free to use table salt, then what adult trace element supplements are needed?

Then, Dean Zi asked several other colleagues, and all of them answered accurately.

"Dean Zi, I'll test you too. One of the colleagues who spoke looked hippie and smiled, stood up and said.

"What are you testing me?" Dean Zi stood on the podium and glanced down at the colleague, as if a little unexpected.

"What kind of tonic is the red one?" hahaha...... before he could finish speaking, he laughed to himself.

Promi knows that the red color is a free and easy tonic, which is mainly for men. Improve their bed kung fu, or in other words, it can also be said to be a kind of Viagra bar. The joke was a bit obscene, Promi thought to himself.

Dean Zi sneered, not embarrassed by him. Looking at the colleague, he said, "I don't know much about the red supplement, but it seems that you use it a lot, and you are quite familiar with it." ”

The colleagues below burst into laughter.

"I'll also ask you, what kind of tonic is black?" Dean Zi asked, looking at the colleague.

Black?Promi's memory was not known about black supplements, he had never seen a black supplement. There is no medicine box in his own medicine box, and he has never seen it in the medicine boxes of Lan Zaoyu, Hong Xiao Dai and other colleagues. It should be said that the medicine boxes of several of their colleagues are the same. He didn't have a supplement, and they didn't either.

Everyone immediately fell silent, as if most people didn't know. Some elderly colleagues, with solemn faces, nodded slightly, as if they were in the know.

"People think it's easy to be a doctor, our supplements are very powerful, no matter what the problem, just take a supplement to solve it. Actually, it's not that simple. Now, let's get started. Dean Zi sank his face and began class.

When I got home from work, my sister hadn't come back yet. Mom wanted to make some kind of dinner to treat Promi's sister, but there was nothing to do. She just set the table in advance. In the middle of the table was a large bouquet of flowers, and underneath it, it was decorated with shiny things.

"What is this?" Promi asked, picking it up.

"Diamonds. It's rare for us to have a dinner, so we must set it up. Mom said.

"Do you throw it away after using it?" Promi asked curiously.

"Are you stupid, is there such a loser? Flowers can be thrown away after a few days of withering. Diamonds won't wither, so you can still use them next time you put them away. Mom said.

"Oh, that's for sure. By the way, my sister is going home for dinner today, and I have prepared some things. Promi said, going back to his room and pulling out the salt he had brought with him in the morning.

"What is this?" asked my mother curiously.

"Salt. So that our dinner can be a little more substantial. Promi said and gave it to her mother.

"Really?"

Promi's mother was skeptical, dipped her finger in a little, tasted it, and sure enough, it was salt. But instead of being very happy, she asked with a solemn expression, "Promi, where did you get all this salt?"

"I bought it. Promi said.

"Nonsense, is the salt in the supermarket white?" said my mother.

It's broken. Promi suddenly remembered that in this world, all the salt purchased from regular channels has a color, and it is painted with different colors according to different uses. White salt, on the other hand, means that it is salt purchased privately from the black market.

"Ah...... It was given to me by a friend. Promi stammered.

"Don't do this next time, it's too dangerous!" Promi's mother said sternly.

"Hmm. Promi agreed.

"Although our family is relatively poor, we are also ambitious. It's okay to eat less salt. When I worked hard with your dad, I wanted you to get into a good school and do what you loved. Mom said, sighing.

"We didn't get what we wanted, but we did our best. Now, your sister is also working hard, and if we help her together, maybe she can also achieve something on the road of art. Don't spend money in the future. Mom said again. Promi nodded in agreement.

Mom took Promi's salt, quickly cut the intermediate dinner bun, and made a few small cuts in everyone's dinner bun, carefully sprinkling a little salt into it. The rest of the salt, my mother took back to the room, and carefully hid it.

After all these things were done, my mother breathed a sigh of relief.

"Promi, don't you know that their condiment industry investigation team has salt dogs?"

"I know. Promi said.

"I used to have a colleague who was ......," Promi's mother said worriedly.

"Knock knock!" suddenly there was a knock on the door.
