At the same time, Yu You wrote five copies of a chemical formula and put them in five envelopes.
Due to geographical reasons, the country does not have much natural rubber resources, and the current chemical technology is relatively backward.
Yu You chose two relatively simple synthetic rubber formulas.
Solution polymerized styrene butadiene rubber and butadiene styrene rubber.
These two synthetic rubbers alone are used in automobile tires, conveyor belts, rubber hoses and general black rubber products.
Extremely versatile.
Yu You folded the envelope and wrote the address on it. The recipient was always the head of the R&D department, without a specific name.
As for the sender, only Xiangyang Commune was written.
She couldn't reveal her true identity. If people knew that she, with only an elementary school diploma, could research the composition of synthetic rubber, she would be regarded as a monster.
It can only be in the form of an anonymous letter.
"This way, my dad's tiller might be able to be made into a rubber tire. It might even advance the country's technological advancement."
Cao Xiu: "Why do you want to write five copies?"
Yu You: "I've inquired, and there are only five chemical plants in our province. I don't know which one is sincere enough to try to develop these. So, we might as well cast a wide net and catch as many as possible."
"By the way, Mom, how about putting Yueyue with me, with An'an and Ningning?"
She only found out this morning that her parents had brought a child back from the city.
In this era of information blockade, the probability of finding relatives is very low.
Either send him to an orphanage, or he has to follow them.
There's nothing you can do about it. The family appears to be nice on the surface, but they are kind-hearted deep down.
Cao Xiu sighed, "This kid has been awake since early this morning and hasn't spoken a word since then. He's just huddled in a corner. If you speak loudly, he'll start shaking with fear."
Yu You: "This is the stress response of those who have been abused. No wonder my brother suddenly became a lot more polite today and is doing things carefully."
The mother and daughter watched Yu Rou feeding the child one spoonful at a time and talking to the child non-stop.
Cao Xiu: "Your sister is very careful, so I'd better put it here and let her watch it for now."
Yu You nodded. Besides being attentive, they probably also shared some common feelings. Perhaps being two wounded people together was a form of healing.
Yu Rou finally coaxed Yueyue into eating by herself, and then she came over.
Yu You: "Sister, how is Yueyue? Is she feeling better?"
Yu Rou said gently, "She's finally willing to eat on her own. Let's spend more time with her and encourage her. I believe she'll get better slowly."
Cao Xiu took the opportunity to take out a few pages of paper copied by Yu You: "This is what your father and I found at the scrap yard yesterday. Take a look."
Yu You and Cao Xiu cooperated: "Mom, all of them are teaching how to make hair flowers and hairpins!"
Cao Xiu: "Who said it wasn't? We've found a treasure. Your sister's handicrafts are top-notch, if nothing else."
"Your father and I got this and went to buy some cloth right away. If we can make it, we can make a lot more money than a small basket."
Yu Rou was very touched. Yesterday, those cloths and two large bags of cloth scraps almost bent her parents' backs.
It turns out that they were all bought for her.
Tears soon filled her dark, bright eyes: "Mom, I..."
Cao Xiu patted her eldest daughter's hand and said, "Why are you crying? How can parents not consider their own children? You have this skill, and Mom will remember it in her heart."
Yu You: "Yes, sister, now that we have the cloth, go buy some rubber bands or something and try to see if you can make it."
Only then did Yu Rou begin to look at the drawings carefully.
Zheng family.
Zheng Minglang had been back for two days, and when he went out for a stroll, his steps involuntarily led him to the Qin family. Actually, he hadn't figured out how to end things with Yu You.
In the small courtyard, three children were running around and making noises, while Yu You, Qin Zhichu and Qin Zhiya were working and chatting.
Yu You asked, "Zhiya, how is the job as a childcare worker?"
Qin Zhiya smiled: "Sister-in-law, it's fine. I work five days and rest two days, which is better than the workers in the city. When I get my salary, I will buy delicious food for everyone."
Today's workers work Monday to Saturday and have Sundays off. The nursery follows the factory's schedule.
But the schools and nurseries of the First Production Team were closed for two days.
Qin Zhichu: "Look at you, you are so beautiful. Let's put aside the question of how much to teach and how little to teach for now. You have to keep an eye on the children."
…
Zheng Minglang stood quietly, watching. Seeing Yu You happy and at ease, he suddenly felt that his own entanglement was just a waste of time.
Behind him, Aunt Zheng passed by and saw her nephew standing there in a daze. She chuckled and went straight home without calling Zheng Minglang.
"Sister-in-law, what do you think of Minglang and Zhiya?"
Tang Lan didn't understand. "What do you mean?"
"We're dating!"
…
State-owned hotel.
Qin Zhiya didn't expect that the person her mother asked her to meet was Zheng Minglang.
What do you say to her? She knows everything about you. Isn't it true? They live next to each other!
But she still had some doubts: "My mom said you've been in love with me for a long time, and you even went to my house to spy on me?"
Zheng Minglang had a dark face and was not good at explaining.
"The elders misunderstood. I wasn't looking at you."
Qin Zhiya: "Oh, that's what I thought. We haven't met much, but it's love at first sight."
From the day she received the news of her demotion, her engagement was canceled. The man she married was her childhood friend.
Although she was still young and didn't understand feelings, she was still hurt badly.
Now, she doesn't have such high expectations for marriage and love. She just hopes to live a carefree and happy life.
Zheng Minglang touched his nose. He actually fell in love at first sight, but not with her.
