In order to appease the feelings of the scientists, Zhang Meixi arranged a break time to drink sour plum soup, paired with the dim sum red bean tea bags of the Spring Breeze Triumph Building. After eating and drinking, the atmosphere became relaxed and cheerful.

Zhang Meixi secretly glanced at everyone's faces and breathed a sigh of relief.

When the refreshment time was over, a seminar was held on "Using X-ray Diffraction to Determine the Spatial Structure of Complex Crystals and Macromolecules".

Zhang Meixi became proud again, it seems to be very coaxing, should it be used or used.

At the Ping An Academy of Sciences, there is an assistant who works as a handyman, named Wu Jiushan, who is a student at Ping An School. He stood out among Ping An's students and was very much loved by Principal Gao.

At the end of the day, Wu Jiushan was in charge of cleaning the room, and another assistant reminded him:

"It's all food and beverage, and the clean-up process can be simplified according to the regulations."

Wu Jiushan nodded, but he still cleaned it up carefully according to strict procedures, in fact, it didn't take much effort, Wu Jiushan was a diligent child.

When the work was finished, Wu Jiushan took off his mask and rubber gloves and returned to the locker room to change his work clothes. I found that the hem of my clothes was rubbed against the bright red and green colors.

The uniform clothing in the real room is a kind of pure cotton white muslin, although it can be received for free, but Wu Jiushan felt that it was a pity to throw it away, and after changing his clothes, he went to wash it.

However, after changing the acidic and alkaline detergents, neither method can be washed, the contaminated color is firmly attached to the white overalls, and the water in the porcelain basin is clear and transparent, and the color has not faded at all. Wu Jiushan frowned, shook his head and hung up his work clothes.

It was sunny for several days in a row, so the next day Wu Jiushan saw a dry overalls, but the hem of the white clothes was on. It's two shocking shades of bright red and turquoise.

Wu Jiushan remembered that Mrs. Corey said yesterday that she made the color of the test tube of the drink, and went to consult her at breakfast. The breakfast at Ping An Academy of Sciences consists of fried fritters and small wontons, as well as fresh bread and sliced beef.

Mrs. Corey carefully counted the number of small ravioli in her bowl. She likes to eat even food. Hearing Wu Jiushan's question, he pondered for a moment and said:

"Missy used to talk about the theory that the color of the drink also affects the appetite of the person, so I made several colors in the hope of improving the taste of the drink. But it was clear that we had failed. ”

Wu Jiushan asked tentatively:

"I think this colorant can be used on fabrics to make dyes for clothes."

Mrs. Corey shook her head, showing no interest at all:

"That's a matter for the fabric merchants, and we don't have time to waste on such trivial matters."

Wu Jiushan asked again:

"I'm interested, can you write me the recipe?"

"Alright then!" Mrs. Corey glanced at Wu Jiushan, and she was also very satisfied with this diligent assistant, so she stood up, walked to the table on the side, and took a pen. Stained with ink, he wrote a few lines on a sticky note.

The scientist's dining room has a scientific twist, with black wood chalk for pen and ink displays. Wu Jiushan happily took the note and went to the dictionary. He also doesn't want to bother people too much.

Wu Jiushan almost forgot to sleep and eat before he finished the dye, and a few days later, he sent five scarves to Mrs. Corey as a thank you. Mrs. Corey is an almost idiot in life, and there are many things that are missing, and the scarf is one of the things that are not lacking. She casually set it aside.

Miss Amy, the assistant lady, was a fashionista, and when she saw Mrs. Correy's shawl, she commented:

"This is a shawl more beautiful than a rainbow after the rain!"

Two days passed. It was getting hotter and hotter, and Miss Amy sat at the front desk of the Academy of Sciences typing, with a shawl over her shoulders that was more fancy than a rainbow. As a female assistant lady of a former detective, it is easy to ask an innocent Chinese boy to order something.

As soon as Zhang Meixi entered the door, she saw Amy's shawl. Also very praised.

When student assistant Wu Jiushan faced Zhang Meixi, he stammered a little and explained the process, especially emphasizing that this was Mrs. Corey's food coloring recipe.

Zhang Meixi encouraged him and said:

"Food additives, used in clothing, are really a reassuring thing, and find a suitable place for real results. That's a lot of credit too. You're amazing, I like that beige the most. ”

Zhang Meixi got her wish and got a beige shawl, which was dyed with handmade coarse cloth, pure and beautiful like the freshest millet husks.

The Industrial Revolution, which first occurred in Britain, was led by skilled workers who continued to improve the process in the process of production, and when the technology developed to a certain level, scientists began to dominate.

However, there are always some stubborn scientists who believe that their ultimate mission is to explore the universe and the meaning of life, and they are not interested in civilian products. Mr. and Mrs. Corey are one of them.

Therefore, they gave up the preferential treatment offered by various industrial promotion associations, and still resolutely went to Shanghai, far away. Strictly speaking, Zhang Meixi is an authentic pragmatist, and will always think of some tricks to arrange chemists to do some civilian things.

The food in the mouth, the clothes on the body.

……

Nanjing Road, a street of fabrics, the crowd is bustling, and the guys are ushered in.

"No shrinkage, no fading, no balling."

"You take a look, three feet is fine, I'll give you one more inch."

The guy measured the size, and deliberately made an inch more than that, and the guest smiled and nodded, and the guy cut a hole with scissors, stabbed and ripped the fabric apart.

A mother and daughter timidly walked into the fabric store, with a store sign written on the door, exclusive sales, and a new rainbow cloth. The mother was in her thirties, coarse and black, and looked haggard, and her daughter was eleven or twelve years old and emaciated. In this world, there are two things that cannot be hidden, coughing and poverty.

The guy is very good, and he didn't show discrimination, and he still greeted warmly:

"Eldest sister, take a look at Xia Zhubu? I can wear it just now, and I can wear it until the end of the fall. ”

The daughter happily stretched out her thin and small hand, and was about to touch the cool and light green summer bamboo cloth. was caught by her mother in a hurry:

"Don't want this, you can't afford it."

She is the one who knows the most about fabrics, from her teens to her thirties, and has been a textile worker for 20 years. When I was working in the factory, I was afraid that I would not get paid, and I prayed every day that the fabric would be more expensive, and more expensive.

It is better to not be able to afford the fabric yourself, and to wear old clothes as an adult.

The heart of the female worker is entangled, she does not know how to read, so she does not know, a thousand years ago there was a poet who wrote a poem to describe such a scene. Selling charcoal, the poor body is single, and the heart is worried about the cold weather.

The textile women workers are too, poor old clothes for three years, and they are still afraid of cheap cloth!
