Mao Geng knew that vinyl records in the nineteenth and twentieth centuries were made of shellac. In 1898, the phonograph with lac as the substrate came out, and in the following thirty or forty years, the record has been using shellac as the substrate, until the later acetate record came out, and the vinyl record with shellac as the substrate has faded from the stage of the record.

In the 19th century, shellac was used to produce picture frames, cosmetic cases, etc., and these products, which were later all made from plastic, were made from shellac in the 19th century. Because of the advantages of shellac that it is easy to form, Westerners completely ignore its medicinal properties, but tap the industrial properties of shellac to the extreme.

If you are in the order of seating, the insects that contribute the most to human beings are, of course, the first silkworm baby that pushes silk, the second is the lac insect that spits gum, and the third is the ash insect.

All right! This was all instilled by the classmate who was the deputy county magistrate with him, and it was later confirmed on the Internet that his words were true.

However, shellac was only used as a medicinal material in the Great Song Dynasty, well, it seems to be also used as a dye, but its use as a medicinal material is absolutely mainstream.

Once when Xinhua Fuguo Xi was there, Mao Geng asked about comfrey, Fuguo Xi and Tan Xiuzhu didn't know where the Great Song Dynasty was produced, only said that this medicine was precious, Mao Geng thought, it should be because it has not yet been artificially stocked, which is rare. After that, Mao Geng put the matter aside.

Today, I suddenly heard that Taiwan produces shellac, which is really gratifying, and Mao Geng decided that he must vigorously display lac insects.

At the same time, the output of Chinese lac in later generations is the third in the world, accounting for only 10% of the output, it is said that the varieties of Chinese lac insects can not catch up with the varieties of India, can not produce high-quality shellac, and the shellac produced seems to be inferior to the lac in Thailand. It seems that imports will have to be started.

Mao Geng felt that today's sea trade channels are unimpeded, as if the problem of lac can be solved through imports in addition to Taiwan's own production, and there is no need to grab lac with the medical industry of the Great Song Dynasty, and he was very excited for a while.

Nature is really generous, giving a lot of human beings, including such wonderful materials as shellac, Mao Geng feels that even in this era, it is impossible to obtain synthetic plastics and rubber for the time being, but with these gifts from nature, in fact, the conditions are not bad, enough to show his strength in industry.

Mao Geng hummed a minor tune all the way back to the Special Mansion.

As soon as he entered the door, Zhang Haisan hurriedly walked over and whispered:

"Maote, Yan Rui has to see you, she has been waiting in the reception room, and she refuses to leave no matter what she says. Look, do you want to see it? ”

"What is she doing here?"

"She wouldn't say." , Zhang Haisan usually deals with the masses in one set, but at this time he showed a depressed look, as if he was helpless against Yan Rui, a woman.

It seems that Zhang Haisan is still not good at dealing with the entanglement of beauties, but he should have immunity, Mao Geng said:

"Alright! It doesn't hurt to meet, you come with me to meet you. ”

Mao Geng is happy today, although he is not like the high-ranking officials of later generations who will closely contact the beauties as soon as they are happy, but if Mao Geng has no gossip about Yan Rui, the gossip actress, how can it be! Mao Geng is not the kind of person who is not serious, he is a little curious, what does this woman want to see herself, she doesn't want to have an affair with herself!

As soon as I entered the reception room, I saw a woman in costume sitting on the sand, presumably Yan Rui, I saw her with a melon seed face, looking forward to her posture, looking at her dress, it was not special, wearing a water-sleeved long skirt Luo shirt with a large right placket, Luo shirt with blue flowers on a white background, covered with a translucent light blue gown, the sleeves of the gown were only over the elbow, and the long-sleeved shirt was covered with short sleeves, which was the characteristic of women's clothing in this era.

I can't tell what age Yan Rui is now, but seven years ago she was a famous prostitute, and at that time she was at least eighteen, so now, to say the least, she is twenty-five or sixteen.

Mao Geng gathered his mind, put away the mood of a qiē gossip, and asked politely:

"This is Yan Rui, right? What are you looking for from me? ”

Yan Rui saw Zhang Haisan coming in with a person, and she had already gotten up from the sand, and when she saw Mao Geng asking, she hurriedly blessed and replied:

"Little girl Yan Rui, meet Maote!"

"Excuse me! Come, sit down and talk. ”

After Mao Geng sat down, Yan Rui sat down, and between her gestures, she was elegant and polite, and naturally, there was an indescribable beauty. Let Mao Geng sigh, he deserves to be a leader in the professional field of the Great Song Dynasty.

"Maote, the little woman Yan Rui heard that women in the Special Administrative Region can work, and Maote also advocates that women make a living independently, so the little girl came here and wanted to make a living in the Special Administrative Region to survive the rest of her life."

"Miss Yan is young and beautiful, radiant, how can you say such depressing words?"

Mao Geng compared Su Zhiyan with Yan Rui in front of him in his heart, and said fairly, in terms of appearance, Yan Thin and Fat should be good at winning, but between the eyebrows, Yan Rui will unconsciously have a professional aura, the so-called smoke and flattery, that's it! Between the autumn waves, Mao Geng had no choice but to avoid Yan Rui's eyes.

"The little woman has suffered setbacks, seven years ago she was scolded by Lord Zhu Xi, and later married into a wealthy family as a concubine, and she was jealous again, so she had to go out of the wealthy family alone, and it was also the little woman's life that was miserable, resulting in such a catastrophe. Since then, the little girl has only thought about making a living independently. The little woman was not able to do anything on her own, and she wanted to make a living in the Special Administrative Region with a little savings of her own. The little girl has been in the SAR for more than half a month, and now when she heard that there was a talk of selling technology, the little woman thought that the little woman would be competent enough to make a living like that garment. Helplessly looking at the posture, there are not one or two who have the heart to buy technology, and most of them are rich businessmen, if everyone is honest and bids with strength, I am afraid that it will not be the turn of the little girl. Alas! ”

Yan Rui sighed faintly, like that, Mao Geng couldn't help but feel pity when I saw it,

"Therefore, the little girl had to think of another idea, so she came straight to Maote, and asked Maote to take pity on the little girl's fate and take care of the little girl, how about it?"

When she said this, Yan Rui's eyes that could speak, a moment of resentment, a moment of expectation, and a moment of anger and joy, made Mao Geng have to quickly avoid his eyes.

Do you want to take care of the woman in front of you? It seems that the current Yan Rui seems to be harmless to humans and animals, Chu Chu is pitiful, for this reason, he should be taken care of. But this woman's identity and background are not decent, and the moral risks she has to take are too great, once the door is opened, the scandal alone is enough for herself to drink a pot.

But if she hardened her heart and refused, Mao Geng looked at Yan Rui, there was sadness in her beauty, and Mao Geng really couldn't bear to say no to her.

Mao Geng was in a good mood today, and the shellac is really uplifting, but now that he encounters this, it is a bit tangled. Mao Geng looked at Yan Rui again, and said in his heart, no wonder Zhang Haisan couldn't let her go, and now that he was replaced by himself, in front of the beauties, he couldn't refuse people thousands of miles away.

"The six technologies that have been announced to be publicly transferred, I'm afraid I won't be able to help you." , Mao Geng's ghost made the gods, and he said such a sentence.

"Oh, the little woman's understanding is that Maute might be able to take care of me in other ways, right?"

Mao Geng seemed to have fallen on the road so far, and smiled bitterly in his heart. Fortunately, the technology I have mastered is very rich, yes, and there are no workarounds.

Mao Geng thinks that first, in terms of cosmetics, it should be helpful to involve a woman like Yan Rui, whether to launch the Da Song version of the lip pencil! In addition, the inner tube of the tire must use knitting technology, only knitting can ensure that it is woven into a satisfactory circle, in order to ensure the quality of the inner tube, plain cloth can not guarantee the quality of the inner tube. In the trial production of knitting machines, it has been arranged, and great efforts are being made at this time, and there should be a breakthrough soon. Once the knitting technology breaks through, it will bring great advantages in the field of textile and garment, weaving we do not compete with the traditional cloth merchants of the Great Song Dynasty, but knitting is a new industry, let Yan Rui run a knitting factory, it should not be bad.

It seems worthwhile to set a role model for a female workplace manager in the Special Administrative Region.
