Professionals are strong, and Chen Lan does the cost accounting, so it is easy for the layman, a novice, to understand it.

"There are three contracts in total, seven products, and the total contract price is exactly 80,000 yuan. The book profit is about 12.3%. After deducting various expenses, the profit is about 5.1%. If the defective rate, interest, machine depreciation and other expenses are added, the final profit will not exceed 3.5%.

Shiratsuki said: "As for processing, ten percent is the highest pursuit, five percent is the lowest requirement, and seven percent is the median. This is 3.5 percent, it is better to store money in the bank for interest, at least the bank is safe and reliable."

Chen Lan was puzzled, "Sister Ding has been in your suitcase factory, has been in charge of production, and has been an accountant. Why don't you have any concept of cost?"

"Haha, if you don't take charge of your business, you don't know how expensive it is. She only knows how to keep accounts and never thinks about the importance of cost accounting."

Baishou told Chen Lan that the profit of a suitcase is only a few dollars or even more than ten dollars, and he is a small expense and waste. He doesn't pay much attention to it, so Ding Yaqiong won't take it seriously.

"Manuals, large-scale industrial production, are in the era of commodity economy, and cannot engage in extensive business."

Baishou smiled, "The truth is right, but it can be used after listening to it. It is very difficult. The contract was signed by Ding Yaqiong and Professor Yang together, why doesn't Professor Yang understand it?"

Chen Lan also smiled, "Don't forget that he is a bridge expert, but he is just a bridge expert. You can even get rid of him in cost calculations of construction projects."

"Hey, don't you all belong to the civil engineering department?" Baishou said curiously.

"You don't understand this." Chen Lan said: "There are seven majors in the Department of Civil Engineering. Strictly divided, Professor Yang's major belongs to engineering, mainly design. The major I studied is science, mainly computing. In fact, I am not very familiar with Professor Yang, and he just took us basic subjects."

"A intellectual and an educated youth who returned to the city, let these two people be responsible for managing the Tengfei Electronic Equipment Factory, and I have to pay my old capital."

Chen Lan asked: "The investment in Tengfei Electronic Equipment Factory is all your money?"

Baishou nodded, "About this, Lan, I want to explain it to you."

"Don't get me wrong, don't be too careful, I just asked casually."

"No, I must say, you must listen."

"Okay, I'll listen."

"First of all, Ding Yaqiong was very helpful to my family during her hometown. My three younger brothers and sisters are now very good at studying, and it depends entirely on her care. She has a good relationship with my mother, and with this, my family has suffered a lot of losses. She also introduced an old cadre to me, so that we can become friends who are old and not bullied too much by others."

Chen Lan listened to her head, only listening and not talking.

"I really started my business and made money by making biscuits. The recipe for biscuits was provided by Mrs. Xiao. Later, the biscuit factory stopped running it, and the recipe alone sold it for 50,000 yuan. This money should belong to Mrs. Xiao and Sister Ding. But they didn't want it, so I have no choice but to acquire Tengfei Electronic Equipment Factory."

Chen Lan asked, "Sister Ding is helping you, didn't you give her a salary?"

"Of course I gave it, and it also included year-end dividends. She and my second uncle are the two who have the most dividends. In the past two or three years, I have given her about 30,000 yuan. My original intention is that she will return to Shanghai and find a stable job. Then, with the money at hand, she can live a wealthy life for several years to offset the hardships she has suffered in the countryside for more than ten years."

Chen Lan smiled, "I didn't expect that she wanted to start her own business."

"Haha... this is nothing. One billion people have 900 million merchants, and there are still 100 million merchants in discussions, but she is not really the businessman."

"Then what are you going to do? Leave it alone? Practice her with so much money?"

"Of course I can't ignore it." said Too farewell: "But it's not possible now. There are two main reasons. One is that it's better to let Sister Ding practice her skills. Fortunately, this is processing of incoming materials and has nothing to do with market sales. Even if you can't make money, you can't lose much. Besides, the contract has been signed, so we can't ask for changes at will."

"What about another reason?"

Baishou smiled, "It's just that Sister Ding is going to marry Professor Yang, she is happy. When she is over, I will tell her about cost calculation."

"That's right." Chen Lan nodded.

Ding Yaqiong got married and was happy.

Chen Lan was also happy because Ding Yaqiong invited her to serve as bridesmaids with Ding Ding.

At this time, the doorbell rang outside. Thousands of troops and horses rang out.

The white-handed was curious that few people came to him at night.

It must be not Chen Lan’s two female classmates, they are watching TV on the second floor.

The doorbell rang twice.

He hurried downstairs from scratch, and he thought it was a migrant worker in the engineering team who came to get things.

He trotted to the yard gate, opened the door and saw that he was his good friend Chen Zifei and his wife Xiao Yang.

While letting in, he hurriedly said, "Hello, Lao Chen, hello, sister-in-law. A rare guest, please come in, please come in."

Chen Zifei and Xiao Yang did not enter the door immediately.

Chen Zifei smiled and said, "I heard that my brother is hiding a sweetheart in the golden house. I wonder if it will be convenient or inconvenient for us to enter."

"Old Chen, what did you say?"

Xiao Yang also smiled, "Old Chen and I were walking after dinner, and we arrived here unknowingly. Old Chen said you live here, and I said you should visit. Xiaobai, did you really not disturb me?"

"Sister-in-law, I welcome you very much."

When I visit you in the evening, there must be something wrong. This is my first feeling.

Baishou led Chen Xiao and his wife into the house and upstairs.

When they arrived at the second floor, they saw two girls watching TV. Chen Xiao and his wife were stunned, thinking that they were playing a trick of trying to do it.

After the introduction was busy, Chen Xiao and his wife breathed a sigh of relief.

When we arrived at the third floor, Chen Lan was already waiting at the stairs.

I made another introduction from scratch.

After looking at Chen Lan, Xiao Yang praised: "Xiaobai, you really have vision."

Chen Zifei said: "Xiaobai is excellent in everything, can he be wrong?"

He said Chen Lan was embarrassed and asked Chen Xiao and his wife to sit down while getting the thermos bottle to pour water.

He took cigarettes to Chen Zifei in his spare time.

Chen Zifei pointed at Xiao Yang, waved his hand to stop smoking, and smiled and said, "In front of my Dr. Xiao, I can't smoke. This is the family rule."

White hands smiled and put away the cigarette.

"Smoking is harmful to health." Xiao Yang is a surgeon, the type who looks beautiful and gentle, but I heard that he is quite majestic at home.

Chen Lan poured the water and wanted to go downstairs, "Mr. Chen, Dr. Xiao, you guys talk."

Xiao Yang called Chen Lan, "Xiao Chen, you sit down, we just come and have a look. It's nothing, you don't need to avoid it."

Nodded with a blank hand.

Chen Lan had no choice but to sit down.

"Old Chen, is there anything wrong with my suitcase factory?" asked by the ground.

"No." Chen Zifei shook his head and said, "Your second uncle is in good condition. We call every three or five days. Besides, if something happens to your suitcase factory, you will definitely know it before me."

Baishou asked with a smile: "Do you understand my second uncle's Mandarin?"
