Qiao Fa is a student of the Royal Military Academy of the Tang Dynasty.

As a student who once followed Li Shimin to go to Goguryeo and made contributions, Qiao Fa did not enter the army after graduation. Instead, he chose to stay in school to teach and became a teacher in the logistics department.

New military uniforms and military boots have now been popularized among the twelve guards of the Tang Dynasty and some important garrisons on the frontier.

Qiao Fa's daily tasks are also very important. In addition to urging the clothing workshop to supply military uniforms and other materials on time and keeping quality in mind, collecting feedback on the use of the distributed materials is also a very important task for him.

In the past year, the most feedback he received was that every time he snorted, he needed to uncover the belt, which was very inconvenient to use.

Also, it is a waste of time when tying shoelaces.

Sometimes when performing tasks, the shoelaces are loose, which may trip you up.

How to solve these problems needs to be considered by Qiao Fa.

For this reason, in recent months, Qiao Fa has been communicating with the tailor of Guanshishan Academy of Arts and the brother's clothing workshop to see if there is any way to solve this problem.

In the end, this question reached Li Kuan's ears.

Isn't this simple yet?

Li Kuan directly provided him with an idea to make a zipper.

However, Li Kuan doesn't understand how to make a zipper.

After explaining the basic principles and application scenarios, the rest is Qiao Fa’s business.

"Teacher Qiao, with this stamping machine, our zipper finally has the opportunity to make it. We have been wasting our way for several months."

Shi Bingming finally breathed a sigh of relief when he looked at the small accessories that were coming off the stamping machine one by one.

Although Li Kuan had provided everyone with the principles and production ideas for zippers before, Shi Bingming and Qiao Fa also tried to make several samples using wood and cloth strips, which basically determined the correctness of the ideas.

However, it is still very difficult to actually make metal zippers.

"Well, there are at least dozens of chain pieces on a zipper, and at most hundreds of chain pieces. If you don't have the help of a steam press and simply rely on hand to make it, it will definitely not be able to meet the needs of military uniforms and military boots."

Qiao Fa also felt that the pressure on his body had been reduced a lot.

This problem has never been solved, and his hairline has been moved back a lot.

By then, there is no need to be ordained, and he will become a monk directly.

"But the cost of making zippers is still too high. We will consider how to use steel to make them later. This will not only be cheaper, but it should also be more durable.

Otherwise, the zipper at the end will break down every few days, and the complaints from the soldiers from the Twelve Guards will probably cause us to collapse."

As Dai Quan's disciple, Shi Bingming is considered to be among the younger generation of craftsmen with very good skills.

Because he often deals with various research institutes of Guanshishan Academy, his knowledge is quite good.

"Well, let's first use copper to produce a batch. This copper is softer than steel after all. After processing, the accuracy of the parts is much higher, and the probability of bad zippers will be much smaller.

If steel is used to make it, the requirements for molds will be much higher and the scrap rate will increase sharply."

Qiao found that the first thing he was thinking about was how to solve the problem, and first put out the zipper so that everyone could see the direction of solving the problem.

Then slowly improve the zipper to reduce the cost of zipper.

"When I first heard His Highness the King of Chu talk about zippers, I thought it was a very simple thing. I didn't expect that a small zipper was no less difficult than making a bicycle, and even more small requirements."

Shi Bingming reviewed what he did after participating in zipper design and production, and felt quite emotional.

Some things that seem difficult are actually relatively simple to solve.

But some things that seem simple are not that easy to solve.

"No matter what, now I finally found the right way to solve the problem. The rest is a process of continuous improvement, which is destined to be a matter of not that simple."

Qiao Fa thought about the situation when he tried the zipper just now, and thought that the zipper might be pulled too far, or it might burst when pulled, or it might get stuck when pulled.

There are still many questions waiting for me later.

"His Royal Highness of Chu asked us to set up a zipper workshop and allocated shares to me, which shows that zippers are still very promising in the future.

Now we are just considering opening the crotch of military pants and using it when using zippers when unzipping hands.

The laces of military boots are also simplified or removed, and used with the zipper on the side.

But actually, zippers should be of very wide use. For example, if we use a quilt, can we also use a zipper as a tool for opening, or if we are on our tops, can we consider removing the buttons and using the zipper directly?”

The two kept discussing the application prospects of the small zipper.

This kind of thing does not involve any military confidentiality, so they hope to expand the scope of use of zippers.

Zippers are used in more places, and even more workshops have started to produce zippers. Some of the problems they were worried about before will be exposed in advance or solved in advance.

This is also a good thing for the logistics department of the Royal Military Academy of the Tang Dynasty.

As for whether this will affect the business of the newly established Shi Qiao Zipper Workshop, it is not something they both are worried about.

"Well, I originally wanted to go to the Royal Patent Office of the Tang Dynasty to apply for a patent. After hearing what you said, I don't have to apply anymore. Let more people produce zippers so that the zipper technology can mature in the shortest time."

As the teacher of the Military Academy, Qiao Fa must first consider the needs of the logistics department.

"No, patents still need to be applied, but we can authorize them to others for free. Otherwise, after the people from other workshops start producing zippers, they will directly go to the Datang Royal Patent Office to apply for a patent, and in turn ask us to pay the patent usage fee, which would be disgusting."

Shi Bingming is a person who has been hang out in society.

Unlike Qiao Fa, who has never really entered society after graduating from the Military Academy and does not know the darkness of the outside world.

In the face of sufficient benefits, courtesy, righteousness, integrity, shame and other things appear very fragile.

"Okay, your concern makes sense, so I'll apply for a patent."

Qiao Fa thought about it and felt that what Shi Bingming said made sense.

If such a scene really occurs, I will definitely have a way to make the other party uncomfortable, but I will definitely be the one who is embarrassed at that time.

He doesn't want a bright future to be affected by these disgusting things.

"There is another question. In addition to supplying zippers to military uniforms, does our Shi Qiao zipper workshop also have to accept orders from other ready-to-wear workshops?"

Shi Bingming had no idea about how Shi Qiao's zipper workshop should operate.

"It depends on the situation. If it is a large-scale demand, we must first consider whether the production capacity of the military uniform can be met; but if it is just a small-scale trial, it is okay to sell a batch to the outside world first.

This can also attract more people to invest in the zipper industry and provide assistance to technological progress."

Qiao Fa thought about it and gave his own judgment.

And some responsive workshops in Chang'an City naturally started moving early.

...

Since its establishment, Belle Bag Workshop has only opened a counter in the Zhenbao Pavilion for sale.

Since these luggage are generally made of crocodile leather and are very expensive, they are the favorites in the circle of noble ladies in Chang'an City.

"Sister Zixia, look at this latest handbag, it seems to be sealed?"

In the Treasure Pavilion of Yang's Tea Building, Zixia and Sisi were shopping there.

The business of Zixia Preparatory Clothing Workshop and Zixia Preparatory Clothing Shop is now on track.

There are fewer and fewer things that need Zixia to worry about in person.

It is early summer now and the weather is not very hot, so Sisi took Zixia to Yang's Tea Building to go shopping.

As a landmark building in Chang'an City, Yang's Tea Building is now the highest-end commercial area in the Tang Dynasty.

You can basically find various mainstream luxury goods in it.

The flagship store of Home Inn on the top floor has made Home Inn's fame soar, surpassing Yuelai Inn in one fell swoop and becoming the most well-known inn in the Tang Dynasty.

Many merchants from other places will take a few days to stay in Home Inn at Yang's Tea Building for a few nights.

As for the naming rights of this building, the price has soared.

However, Yang Benman, who tried the benefits, always firmly occupied the name with the same priority.

Nowadays, people rarely use the tallest building in the Tang Dynasty to call this building, but instead call it the Yang Family Tea Building in habitually.

Yang's Tea also successfully stood firm in the second place in the Tang Dynasty with this huge advertisement.

Many businesses from other places who want to purchase tea or tea bricks will give priority to the production of Yang's Tea Workshop.

"This girl has a good opinion. This is the new handbag we just launched yesterday, with a limited supply of 100 pieces.

This handbag uses the latest technology jointly developed by the Royal Military Academy of the Tang Dynasty and Guanshishan Academy, which can make your daily use very convenient."

The guys from the Treasure Pavilion are all very professional nowadays.

Because of the good treatment, these guys have very high stability.

Many people have been working here since their opening.

So when they see Zixia and Sisi, they know how to sell it.

"This is just a handbag, is it as exaggerated as you said?"

Zixia couldn't help but raise her own doubts.

If it weren't for the production of the Treasure Pavilion, it would have always been a fine product.
