"Your fourth uncle doesn't dare to demolish it, do you demolish it?" Ning Yunxi said when he saw his son's little hand touching him.
Leilei immediately retracted his little hand: "Uncle Xiaosi?"
"Yes, it was brought by your fourth uncle." Ning Yunxi said, and then he opened the letter Li De sent to her by himself.
In the evening, Meng Chenhao came back and learned that Li De had sent her a letter, so he went into the room and asked her: "What did he do to write to you?"
"It's nothing. Last time I asked him to find some materials for me. He helped me find them abroad and got them for me." Ning Yunxi told him, "It's for making a children's schoolbag for protection of the spine."
Regarding making schoolbags for children, Meng Chenhao knew that his wife had been doing it all the time. Because her wife attached great importance to the health of her children. As people pay more attention to education, the more books they have to read, and the weight of the schoolbags naturally increased. But how to make such a schoolbag is light and good, it seems to be a big problem.
"Plastic products, our country's plastic raw materials industry has not yet developed." Ning Yunxi said. For a long time, plastic raw materials were not the industrial advantages of their own country. Ning Yunxi knew that. Not only that, as long as it is chemical products, it is.
If the raw material technology cannot develop, all industrial chains based on raw materials will have to bear huge supply pressure, which is equivalent to being strangled by others.
So is it easy to make a schoolbag with a little technological content for your child? Of course it is not simple. Ordinary consumers will never know that the efforts and hard work of scientific and technological personnel from all walks of life are included in it.
Meng Chenhao picked up the glass jars placed in the box she opened. The white particles in the jars made people feel as mysterious as snowflakes. He couldn't understand them, only his wife could understand them.
Turning his head, Meng Chenhao found that his son had been standing on the chair and staring at these small particles, and couldn't help but ask: "Do you understand?"
Dad doesn’t understand your three-year-old son?
When Leilei was asked by his father, he said the truth: "Mom said that the toys were made from this." The plastic toys he played with were actually made from these small particles. Of course, Leilei was curious and thought about how to make them. He kept waiting for his mother to demonstrate to him.
In response to this, Ning Yunxi had long emphasized to his son: "This demonstration needs to be entered into a laboratory or factory. Mom can't take you to see it now. You have to grow up to understand it."
Xiao Leilei pouted his little mouth aggrievedly.
I was afraid that my son would be curious and took it out to eat it. Ning Yunxi locked all these things in the cabinet. Who told me that a child of this age was a newborn calf who was not afraid of tigers and had the courage to not fear death, so he had to touch and eat everything.
Leilei tasted the lesson he taught me the next day.
The next evening, he and his aunt had just returned home from school, and the doctor brother came over with a bicycle carrying a schoolbag.
After getting good things from abroad, Ning Yunxi wanted to share with the students involved in the majors, so he called Lin Shangxian and the students studying chemical engineering. When Lin Shangxian arrived, he climbed upstairs and knocked on the door of the Meng family.
When Leilei heard his brother's footsteps, he knew it was his brother, so he rushed over and opened the door for his brother.
"Leile." Lin Shangxian saw the baby touching the baby's little head, and a smile appeared on his face.
