Li Qingquan pulled Chen Wanrong to his room. As soon as he entered the room, Chen Wanrong remembered the tea smell he smelled for the first time in this room. His nose couldn't help but twitched a few times, but there was no refreshing tea fragrance. There were only two fine porcelain teapots on the table, not the three I saw last time.

"Wanrong, sit, sit." Li Qingquan moved a chair and warmly greeted Chen Wanrong and sat down.

Chen Wanrong thanked him and sat down. Li Qingquan picked up a teacup, poured a little tea from the teapot and put it in the cup, shook it a few times and washed it, and poured it into an empty bowl. Then he picked up the teapot and poured a cup of tea. He handed it over with his polite hands: "Wanrong, you have been walking for a long time and are thirsty, drink a cup of tea to moisten your throat."

After walking for half a day, Chen Wanrong was really thirsty. He stood up, took it with his polite hands, thanked him, took a sip, it was delicious, not coarse tea, but probably the tea that Li Qingquan drank for ordinary customers. Chen Wanrong remembered the first time he entered the house to drink tea, and couldn't help but feel a little funny. This time, he actually gave him good tea as soon as he came. After skipping the "tea" stage, he went directly to the "tea" stage. The treatment difference was really big.

Just as Chen Wanrong turned his mind, Li Qingquan sat on his chair, lying half-lying and leaning: "Wanrong, Mr. Zheng did not come to pick up the goods today, and the Qingcheng snowballs did not soak. Please forgive me."

No matter how true or false his words were, he was a very good person. It was not easy for him to say this in person. Chen Wanrong, an open-minded person, would not care about the quality of a sip of tea? He smiled and said, "My old man is so serious. I am thirsty. I am very grateful to have the old man give him a cup of tea."

Li Qingquan laughed loudly, sat down again, blinked his eyes, and was a little naughty: "Wanrong, guess what good thing I showed you?"

Chen Wanrong is smart and capable, but he is not a god who can calculate and calculate. He has no ability to predict the unknown, but Chen Wanrong is smart and flattered Li Qingquan a little: "Old man, you have a great family and have many treasures, so how can I guess? Old man, you have to treasure your own good things. If there is any inconvenience, you don't have to let me know."

The ancients once warned us that "seeing fish under the water is an ominous sign", which means that knowing other people's privacy will make people afraid. Chen Wanrong understood this truth deeply and then refused. He focused on exploring other people's secrets. He was a "paparazzi". Although Chen Wanrong was a little curious, he was not the kind of person who had no cultivation.

Li Qingquan rejected Chen Wanrong's proposal: "Wanrong, don't worry, you have to see this thing. This thing is related to you. Wanrong, guess again, see if you can guess it."

Chen Wanrong changed his mind and realized something, and asked, "Can Mr. Li use my tanning agent to make leather?"

"That's right!" Li Qingquan stopped leaning on the chair, stood up straight, slapped his hands, and praised loudly: "Wanrong, you saw the opportunity so quickly. You thought of it just after I raised my head, it was amazing. This also shows that Wanrong is very confident in this tanning agent!"

Li Qingquan has nothing to do with him here, and it is not difficult to guess at all. Chen Wanrong said humbly: "My old man has been too much. I still have some confidence in this tanning agent." This method of tanning can stand the verification, so how could Chen Wanrong have no confidence?

Standing up, Li Qingquan walked to a box by the wall, opened the box and took out two pieces of leather the size of a palm, returned to the table, put the two pieces of leather on the table, and waved to Chen Wanrong: "Wanrong, come and take a look."

He didn't say that Chen Wanrong had to find out what was going on. He walked to the table with a teacup and looked at two pieces of leather.

Li Qingquan glanced at Chen Wanrong and felt a little proud: "Wanrong, can you tell which one is made of your tanning agent?" In his imagination, he was a master with decades of experience. Although Chen Wanrong performed well and was eye-catching, he was still far behind himself. In the end, he had to give the answer by himself and couldn't help but feel a little contemptuous.

Chen Wanrong didn't think about it and pushed the leather on his right hand in front of Li Qingquan: "Old man, if I'm not mistaken, this one should be it."

Li Qingquan did not express his opinion, but asked back: "Wanrong, are you guessing correctly?"

"You can't be wrong!" Chen Wanrong explained with confidence: "Old man, although I haven't touched it before, I don't know how it feels, but you can tell it just by looking at the appearance. My surface is smooth, without dead wrinkles, without dead wrinkles, clear and natural textures, full of beauty, and it looks comfortable. This one is a little light in luster, with a little dead wrinkles on the surface, which is not very pleasant to see."

Li Qingquan was very surprised, shocked and admired. He patted the table with his right hand and exclaimed: "Wanrong, you are so amazing. You have never made leather but have the eyes of a master. You have a sharp eye, so sharp!"

He didn't know that leather products in modern society are all over the streets, including leather bags, leather jackets, leather pants, leather gloves, leather shoes, and leather clips. Leather in modern society mainly comes from two aspects: one is artificial leather and the other is natural leather. Those unscrupulous businesses use inferior products as good products, and use fake products to deceive people by saying that artificial leather is cowhide.

If you want to avoid being deceived, you have to learn to identify the authenticity of leather. Chen Wanrong, a top student in the Chemical Engineering College, needs to distinguish the authenticity of leather as a "professional counterpart". It is very easy. He has long been familiar with the quality of leather, and he can even tell him that he is 556 with his eyes closed. When he sees these two leathers, he can recognize them at a glance.

"The old man is too much." Chen Wanrong said humbly, gently stroked the left index finger on the left skin, then on the right skin, pointing to the leather in front of Li Qingquan and said: "This picture is soft and comfortable to touch. This picture is a little hard and has a bit of a rough wood. Old man, I wonder if I think I am right?"

"Yes, yes! That's right!" Li Qingquan kept praising: "Wanrong, the benefits are more than this. Wanrong, look at it." He picked up the leather in front of him, folded it in half, and then put it on the table and patted it hard for a few times before he let go. As soon as he loosened his hand, the leather immediately popped up and slowly returned to its original state, without leaving any trace, as if it had not been folded in half.

I folded the other one in half, slapped it on the table for a few slaps, loosened it, and slowly returned to its original state, leaving an angle of about ten or twenty degrees. Not only did I not fully restore it to its original state, there was a faint white mark on the folded side.

"Excellent flexibility!" Li Qingquan looked at the leather and came to the conclusion.

The main requirement of leather is to have exquisite appearance, shiny, good feel and good flexibility. The leather made with Chen Wanrong Tanning Reagent fully meets these requirements and improves the quality to the next level.

Chen Wanrong admired Li Qingquan's attitude of trying it out: "The old man is really decisive and can try it out as soon as he says, and he has nothing to say."

Li Qingquan smiled and shook his hand and said, "Wanrong, don't say something nice. Let me tell you the truth. At first, I really didn't believe you could make good leather. I used a piece of waste sheepskin and soaked it. I didn't expect it to work well. So I put some good skin on it. It was too late and it wasn't good yet. I'll show you tomorrow."

"A expert can tell if there is any one at a glance." He is a master. He can tell that Chen Wanrong's tanning agent is very effective when he tries. He doesn't have to wait for all the leather to be done to know the result.

"Okay, I'll bother you by then." Chen Wanrong said with a smile.

Li Qingquan sat down and waved to Chen Wanrong to sit down. This time, he did not lie half lying and leaning halfway, but sat straight and looked at Chen Wanrong: "Wanrong, how much does this tanning agent cost per pound?"

The business came to the door, and Chen Wanrong was very pleased and pondered for a moment: "Old man, if someone wants it, the price will definitely be higher. If you want it, you will cost 100 cents per pound."

"One hundred people per pound?" Li Qingquan shrank his mouth in fear.

The consumption of tanning agent is very large. Unlike the amount of hot alkali only needs about ten kilograms per month, tanning agent consumes more than a thousand and two thousand kilograms per month, and more than a hundred and two hundred jin of coins will be added in a month. This is a large amount, and Li Qingquan cannot be surprised.

After a pause, Li Qingquan quited: "Wanrong, can it be cheaper? Ten cents per pound, how about it? Ten cents per pound, I want one hundred pounds." After diluting one hundred pounds, it can be used for at least ten days. It costs about thirty pounds per month, and this cost is still acceptable.

Chen Wanrong rejected it without thinking: "Old man, one hundred coins per pound cannot be lost."

Li Qingquan sizzled, feeling a little angry: "Wanrong, your tanning agent is a good thing, it is the best tanning agent I have ever seen in my life. But, I guess you used alum. How much money can alum be worth? Aren't you cheating me?"

The tanning agent mixed with alum and salt is different according to the temperature ratio. Even if Li Qingquan knows that he uses alum, he is not afraid of learning the technique. Chen Wanrong is not worried about this and smiles slightly: "Old man, I have heard of a philosophical couplet 'Essence in the world is knowledgeable'. No matter which raw material I use, as long as the things I make are good, it is knowledge. Old man, knowledge is valuable." There was no word patent in the Tang Dynasty, and the word knowledge was easy for Li Qingquan to understand.

"The world is full of knowledge!" Li Qingquan commented and looked at Chen Wanrong in surprise: "Wanrong, you are really knowledgeable. This couplet is a warning to the world!"

Humility is Chen Wanrong's virtue, so how can he rob people of beauty? He smiled and said, "Mr. Wu's famous sayings, I heard Zairong say."

"Oh!" Li Qingquan said, and savored again: "Essence of the world is knowledgeable! Well said, so well said! Wanrong, your tanning agent is good, and the leather is good, but if you wear shoes on your feet, who can stare at your feet? Good and bad skins are the same, so you can warm your feet! Wanrong, you are too high, I don't want it."

This makes sense. Apart from people who like to show off, who would pay attention to the shoes on other people's feet? The price of 100 ci is too high, exceeding Li Qingquan's ability to bear it. This is very firm.

According to Chen Wanrong, the alum method is better than the tanning agent used by Li Qingquan now. As long as the food is good, Li Qingquan will definitely buy it. He did not calculate the market tolerance. After hearing this, he was stunned and thought to himself how to deal with it so as not to ruin this transaction?
