On the morning of 16 August, Li Longji and his family of three left by car.

Li Chengqi was a step late, he had to look at Princess Jinxian and Ye Fashan, and he could not leave until the two of them left.

When I left, I brought a lot of snacks from the Zhuangzi, saying that I would take them back for my family to eat.

Princess Jinxian hadn't seen Li Yi since she saw her, and she was sullen when she left.

Ye Fashan was very calm, looking at the scenery of the Li family Zhuangzi while walking, he saw it once when he came yesterday, but he couldn't see enough.

"Brother Yi, I'm leaving, don't worry, what you handed over to me, I will definitely help you publicize it, this thing is good."

Li Chengqi said with a box in his hand.

Inside the box is the shoe polish made by Li Yi, black and red.

Wealthy people in Datang, whether male or female, like to wear leather boots, especially in winter.

The color of the boots is the normal color, wipe with water during maintenance, and then dry again.

Li Yi used white rod wax and turpentine distilled from pine oil, mixed with black ink, to make shoe polish.

A few days ago, it rained, and the farmer who wore leather shoes touched the water, and did not deal with it in time, and there was a problem, mainly pannitrate.

This is rubbed with vinegar and then shoe polish.

But without shoe polish, this shoe will not work.

When making leather, it is necessary to achieve an acid-base balance, first nitrate, that is, to take plant ash, and then to rub it with salt.

Others soak the leaves of the plant first, and then put the skin in it and soak it together.

To what extent it is kneaded, it is a craft.

In today's people, it seems to be a secret recipe, but in fact, Li Yi knows that it is the intervention of acid and alkali on leather, and then returns to balance.

When water is encountered, the acid-base balance is broken and the alkali or salt comes out.

You can only resynthesize it, and then hit shoe polish, otherwise it will still be nitrated.

The dealer looked very sad, obviously knowing that the leather boots looked like this, and they would be ugly in the future.

Li Yi felt that this was a small problem and should make the dealer happy.

So shoe polish was made, and the dealer was really happy after disposing of the shoes.

And the shoes were colored, which was originally brown and yellow, and changed to black.

In fact, there is shoe polish without ink, which is the primary color when smeared, and the dealer has to make it black.

Li Yi is ready to sell this thing, and other people's shoes will have the same problem, as long as the shoe polish is good.

Seeing that it is raining outside, hit it first, run out, come back and wipe it off quickly, no problem, it doesn't matter if the soles seep in.

This shoe polish is simple to make, the effect is good, and people who can wear leather shoes are not bad for the money to buy shoe polish.

Isn't it more beautiful for a woman to wear red leather boots? For example, the story in medical school, there is a pair of red leather shoes......

Li Chengqi took a lot of it, and he wanted to help publicize it, so that it would be sold later.

Xinyan and the others, including their followers, also took ten portions each, plus a brush made of pig hair, and went back to play with oil.

"Look, look, I'll just say, after two days, he won't be idle."

In the afternoon, Yao Chong appeared in the political hall wearing bright leather boots that had changed his original color to black.

He thinks it's good-looking, bright.

He wears short boots, which are actually leather shoes, invented by Li Zhuangzi, long leather boots are hot to wear in summer, unless they are cavalry.

Nowadays, long cloth boots are not in fashion, long cloth boots are a symbol of the wealthy, and they can make boots out of so much cloth.

Ordinary people wear shoes woven of grass or bamboo leaves, and they usually go out with a few pairs of shoes.

Those who wear cloth shoes are rich, and those who wear leather shoes are even richer.

Yao Chong, who wore leather shoes and shoe polish, was beautiful in his heart, but he said that Li Yi could toss.

The people in the political hall are used to it, not just Zhang Shuo and Lu Huaishen.

One day, if Yao Xiangru didn't mention two sentences about Li Yi, there would be less fun on this day.

"Yao Xiang, Li Yi said, you can't wear black shoes, you can't wear white socks, and you usually wear black shoes with cloth shoes, but they don't look good with white ones."

Zhang said that he felt awkward, Yao Chong's leather shoes were black, and then looked at the white satin socks, the contrast was strong.

"What does he say? He doesn't understand. Yao Chong replied and entered his 'office'.

It didn't take long to come out, and the white socks before were gone, and they were replaced with brown socks.

Li Family Zhuangzi.

"Look, shoes, wipe like this, first clean off the dust with water, then wipe clean and then ......"

Li Yi sat on a small horse, with a folding wooden chair in front of him, on which sat a sad-faced farmer.

One of the farmer's feet was on the wooden shelf in front of Li Yi, and there were a pair of leather shoes on his feet.

Li Yi was there to explain and shine his shoes, surrounded by a group of children.

These children are in poor conditions and have no newspapers to sell.

They were called in by the newspaper sellers to learn how to shine someone's shoes.

Li Yi wiped it very seriously, brushed it with a small brush, then dried it with a cloth, put on a little oil, and brushed it with another large brush.

After that, he rubbed the cloth there and kept his shoes shiny.

When the model dealer is nervous and asks the proprietor to shine his shoes, will it be dead?

"Change one foot, you sit down, everyone see, the leather shoes of the low top, in order not to rub the socks to color, you have to wrap them with other cloths......"

Li Yi said a word to the banker and demonstrated again.

The children watched earnestly that they were going to be assigned to help others shine their shoes in exchange for living expenses.

A whole set of things, Zhuangzi rented them out, and returned them when they made money.

In the future, you will have to buy your own shoe polish, and the price that Zhuangzi gives them is not high, and you have to say that the price is high when you publicize it to the outside world.

"You don't need to put too much shoe polish, the main thing is to rub, rub it over, look, it's not very bright, I said don't shake your legs."

Li Yi operated and warned the dealer again.

"Proprietor, I'm afraid that when you finish wiping, they will beat me." The dealer was about to cry.

"If you can't die, go to me if you're injured, I'll give you medical treatment, don't be afraid." Li Yi is very bad, according to the words of the banker.

The children laughed, and then one by one stepped forward, and the other farmers cooperated.

Li Yi introduced the business experience.

"When you meet the kind of person who wants to wipe and hesitates, you can say wipe it for free, remember to wipe one, and don't pay for it when you're done."

Li Yi teaches children and is very patient.

"What if he doesn't wipe it?" Children feel sorry for the waste of shoe polish for one shoe.

"It's impossible, one is polished, the other is ugly, it's better not to rub it." Li Yi guaranteed the ticket.

"I'll show you again, yo, this Li family Zhuangzi, don't you shine your shoes? Don't have the money to try it. ”

Li Yi sat down again and said to the next banker.

The next dealer sat down, Li Yi began to wipe patiently, and when he finished wiping this one, he raised his head and smiled: "Okay, let's go, don't need money." ”

The farmer stood up and looked down, one shoe was shiny, and the other was rustic.

He tried to take a step, but found that he couldn't move on his legs.

"Hahahaha~~" The children laughed again, and sure enough, the two shoes were different, and they looked very awkward.

"Don't worry, wait until they finish buying shoe polish and change the color themselves, and then you go out, otherwise it will be very oil-intensive to change the color, and the shoes with fledging can't be wiped ......"

Li Yi continued to pass on his experience, the shoes that turned over the wool were not easy to operate, so no one would wear them now, and he would design them later.
