A professor's rebirth: I entered Tsinghua University in 1977.

"Teacher Shen, you don't need to worry about him. His father is Uncle Liu Chu'an, who is now the Party Branch Secretary of Yanggou Farm. He's a very upright and good cadre!"

Ai Xiaoyu repeatedly admired the medals and certificates of merit in her hands, especially the photo of Liu Hongyi in military uniform on her work ID card, and said to Shen Wenshan.

Shen Wenshan didn't know Ai Xiaoyu, but this kind of quiet and pretty girl was easy to gain people's favor and trust. Shen Wenshan's intuition told her that Liu Hongyi and Ai Xiaoyu were both trustworthy young people.

"Technician Liu, that's amazing..."

Shen Wenshan praised sincerely.

Liu Hongyi said modestly: "Teacher Shen, you should just call me Xiao Liu."

Shen Wenshan smiled and said, "It's just that you're too young. If you were a few years older, I'd probably have to call you Engineer Liu... By the way, Technician Liu, have you asked my old Chen to do research? Has the leadership approved it?"

Liu Hongyi hurriedly said, "I've reported this to Director Duan Weimin of the Third Institute, and Director Duan has approved it... Teacher Shen, our Third Institute is a deputy army-level unit, and Director Duan is a general-level unit."

Shen Wenshan nodded quickly and said, "I know the Third Institute. It's a very powerful unit... However, Technician Liu, I'm afraid it will be difficult for my son, Lao Chen, to join your research group."

"What do you mean, Mr. Shen?"

Liu Hongyi showed a concerned expression.

Shen Wenshan's face turned somewhat gloomy. After a moment of silence, she said, "He is currently in the Jiuan Third Labor Camp. He has been sentenced to seven years in prison..."

"what?"

This was beyond Liu Hongyi's expectations.

Originally, it was thought that Chen Jiayou would at most go to work on a farm, but unexpectedly he was sentenced to seven years in prison.

"How could this be?"

Shen Wenshan's face showed anger: "My husband, Mr. Chen, works in teaching and research. In the field of optical physics, we need to learn from some advanced technologies from abroad, so he used to subscribe to some foreign language journals for reference... These foreign language journals are kept in his office..."

Liu Hongyi learned the reason.

Chen Jiayou's experience is by no means an isolated case. But the fact that he was sentenced to seven years in prison suggests that Chen Jiayou must have offended some powerful figure who was deliberately targeting him.

This kind of relatively pure intellectuals often do not understand the ways of the world, speak their mind without thinking, and offend others without realizing it.

It was only after Liu Hongyi entered the administrative system that he gradually understood these things.

"Teacher Shen, no matter what, I'd better go to Jiu'an to see Professor Chen first. I'll ask Professor Chen for his opinion first, and then I'll see if I can think of any solution..."

There is no doubt that technologies such as optical sights, laser rangefinders, ballistic calculators, and infrared night vision goggles play an important role in modern warfare.

It can enable existing equipment to exert power far beyond its design requirements.

For example, the .35 automatic grenade he developed currently has mechanical sights installed. Aiming directly at the enemy's machine gun emplacements, it may take several rounds to hit an enemy. With the addition of an optical sight, perhaps two or three rounds will be enough to hit an enemy, effectively doubling its combat effectiveness.

Moreover, the more accurate your attack is, the lower the risk of being killed by the enemy.

It is far from as simple as one plus one equals two.

If combined with a laser rangefinder and infrared night vision device, it will have a great advantage in night battles and be even more powerful.

In these areas, Chen Jiayou may not be the most authoritative scientist in the country, but he is the top expert that Liu Hongyi can currently contact.

As a reborn person, the main thing is to be one step ahead.

Shen Wenshan naturally had no objection to this.

This is already the worst situation. Even if Liu Hongyi is helpless, the situation will not be worse than it is now.

After finding out Chen Jiayou's whereabouts, Liu Hongyi did not leave immediately, but chatted with Shen Wenshan about embroidery.

Of course Liu Hongyi doesn't know embroidery, but he understands the market.

"Teacher Shen, who are the main customers for the products produced by our factory?"

Shen Wenshan shook her head and said, "We mainly sell to the supply and marketing cooperatives. However, our factory was established not long ago, and the workers' skills are still at the elementary level. We can only produce some basic products, and most of them are third-rate or even substandard products... The supply and marketing cooperatives offer low prices, so they are not very willing to buy..."

We are currently in the era of planned economy, and even the most basic small street factory produces according to plan.

The supply and marketing cooperative gives the factory a certain number of indicators, and the factory will produce that many products.

Embroidery is not a specialty of Chuzhou. Most of the skilled workers are concentrated in the provincial capital, Daning. If Shen Wenshan hadn't come to Chuzhou, this small street factory probably wouldn't have been able to produce even third-grade products, just a bunch of substandard or even defective products.

"Teacher, is there any way to quickly improve the workers' technical level?"

"No……"

Shen Wenshan shook her head.

Embroidery is a skill that requires patience and dedication; there are no shortcuts to mastering it.

Liu Hongyi thought for a moment and said, "Teacher, do you know cross-stitch?"

"Cross stitch? I know."

Shen Wenshan was a little surprised, wondering why Liu Hongyi suddenly brought this up. Cross-stitch and Daning embroidery (Ning embroidery) are not the same thing.

"Cross-stitch originated in the Huangmei region of my country and later spread overseas. It's almost lost in China...Technician Liu, why do you ask this?"

"I heard that this thing is quite popular abroad, especially in small notebooks and South Korea, where cross-stitch is very popular."

"Teacher Shen, I have a suggestion. Let's see if we can revive cross-stitch. My suggestion is to turn it into an industrialized assembly line product. Design the pattern in advance, and then add the grid and embroidery thread. Anyone can get this product and embroider it at home without the need for a teacher..."

Liu Hongyi recalled his impression of cross-stitch and spoke slowly.

This was another way he thought of to earn foreign exchange for the Chuzhou area.

Liu Hongyi remembers clearly that many years later, cross-stitch was indeed popular for a while. He had a cross-stitch piece depicting the rising sun hanging in his living room, and it was quite beautiful.

Launching cross-stitch now should give us a head start.

As long as it can be linked to foreign exchange earnings, generally speaking, the higher authorities will give the green light.

Let’s make this cross-stitch first, produce and sell it on a small scale, and then we can make a big move when the overall environment starts to improve.

Shen Wenshan closed her eyes and thought for a moment, then the corners of her mouth slowly turned up, revealing a smile.

Obviously, she had understood what Liu Hongyi meant.

"good idea!"
