To build a house in the countryside, build a two-story house with a total of 10 rooms, plus a kitchen and two pigsties, and burn bricks in a ready-made earthen kiln, it costs about 8,000 yuan.

To build a house in the town, bricks are bought from a brick factory, and building materials such as sand, stones, cement, and steel bars are purchased from nearby factories, and the cost per square meter is cheaper than burning bricks yourself.

The cost of burning bricks by yourself is cheaper than buying them from a brick factory. However, transportation in rural areas is inconvenient, and to transport sand, stones, steel bars, cement and other things, you either need to ask people to help or hire pack horses to transport them.

The bricks in Qianshi Town only cost a few cents a piece, a car of lime is more than 200 yuan, and a car of cement is about 500 yuan.

A cart of yellow sand costs twenty or thirty yuan, if there are acquaintances working in the sand field, you can pull away a few cars of sand without money, and the sand field ten kilometers away from Wufeng Village has almost no production cost.

Building a house in the town saves a lot of freight, but the bricks are a little more expensive, and the cost per square meter is about 40 yuan, and if it is built ordinary, the cost per square meter will not cost 30 yuan.

My parents had more than 6,000 yuan in their hands and borrowed 30,000 yuan from their boss, even if the cost per square meter was as high as 40, they could build a house of 900 square meters, with an area of 300 square meters on each floor, and 36,000 yuan was exactly three floors.

In less than a month, Chen Yu's new house was built with two floors, and the remaining floor could be completed in more than ten days, and it would take two or three months to install the house inside and out.

"Xiaoyu, what color tiles do you like?" While eating dinner, Chen Weiguo suddenly asked.

"Dad, the decoration of the house, let's get it after a while." Chen Yu said.

"While the shelves are all there now, get the exterior wall tiles right first, so as not to build shelves again." Chen Weiguo said.

"Dad, the exterior wall tiles will not be pasted, after a long time, the tiles attached to the outside of the wall may fall, in case the passer-by is killed or injured, we have to lose money." Chen Yu said.

"It's the same, there are too many people coming and going, and if the tiles fall and hit someone else, then it's a big problem." Chen Weiguo nodded approvingly.

"Paint the outside of the wall directly, the light yellow paint is better, and with a little brown stripes, it should look good to paint the exterior wall." Chen Yu said.

"Well, do as you say." Chen Weiguo nodded in agreement.

The next morning, Chen Yu rushed to Wang's maintenance factory.

"Xiao Chen, did you have breakfast?" Wang Zhengxin, who was holding a bowl of fried noodles and eating heavily, asked him with a smile.

"Eat." Chen Yu replied and said, "Uncle Wang, I'm in." ”

"Well, you're busy first." Wang Zhengxin said with a smile.

Walking into the room, Chen Yu picked up the tools, quickly dismantled a TV, and got busy with his mind.

At lunchtime, a middle-aged man full of engine oil walked in from outside and asked in surprise, "Can you repair machine tools?" ”

"What's wrong with your machine?" Chen Yu raised his head and asked.

"There are some problems with the size of the cut parts." The middle-aged man frowned secretly, and when he saw that adults were present, his expression was quite calm.

"Where are your machines?" Chen Yu asked again.

"You're from Sanyang Machinery Factory, right?" Wang Zhengxin said thoughtfully.

"Well, I'm Li Dazhu, the director of the maintenance department of Sanyang Machinery Factory." The middle-aged man nodded.

"Xiao Chen, let's take a look." Wang Zhengxin said.

"Hmm." Chen Yu nodded.

followed Li Dazhu into Sanyang Machinery Factory, looked at the machine tool that saw the problem, and after secretly pondering it, Chen Yu was settled.

"Xiao Chen, how is it? Can it be fixed? Wang Zhengxin asked.

"It can be repaired, the key is how much money are they willing to pay for Sanyang Machinery Factory?" Chen Yu said with a smile.

"Repair this machine tool, and our factory will give you a thousand yuan." Li Dazhu said.

"Xiao Chen?" Wang Zhengxin asked.

"This machine is imported from abroad...... In this way, I don't want you to give 10,000 or 20,000 yuan, give us 8,000 yuan, and promise that this machine tool will be repaired to you within a week. Chen Yu said confidently.

"Why don't you grab it?" Li Dazhu asked angrily.

"You ask foreigners who stay in the Han Kingdom to repair, and the round-trip air ticket, plus salary, and travel expenses, will cost at least 20,000 or 30,000 yuan, right? To repair a machine tool imported from a foreign country, I only charge 8,000, which is interesting enough. Chen Yu said with a smile.

"Just you? How old are you? If you can fix this machine, my hammer will be able to hammer out an aircraft carrier. Li Dazhu was skeptical.

"This is the fixture, this is the speed regulation ......" Chen Yu pointed to the parts of the machine tool, and calmly introduced the names and uses of each part.

Seeing that the other party knew everything about the imported machine tool in front of him, Li Dazhu was shocked in his heart, and after calming down, he asked again; "Did you really fix this machine?"

"I just took a look, and I will repair 90% of the machinery and equipment in your factory." Chen Yu said confidently.

"I'll ask our factory director if he wants you to fix it." Li Dazhu said.

Seeing the other party leaving, Wang Zhengxin asked; "Xiao Chen, can you really repair this machine tool?"

"Uncle Wang, what am I lying to you for?" Chen Yu asked with a smile.

"If you ask a foreigner to repair a machine tool, it really costs twenty or thirty thousand?" Wang Zhengxin asked suspiciously.

"No matter how big or small the problem is, even if a foreigner comes to tighten a screw, it will cost 20,000 or 30,000 yuan, travel expenses, air tickets, entertainment expenses, and the money that foreigners want, all of which add up, sometimes more than 20,000 or 30,000." Chen Yu said.

Wang Zhengxin was shocked, foreigners come to repair a machine tool, it will cost 20,000 or 30,000 yuan, he repaired a TV, in addition to the cost of parts, he also earned about 20 yuan, calculated, only one-thousandth of a foreigner.

"Twenty or thirty thousand yuan is still cheap, I heard that some expensive imported equipment, foreigners come to repair once, often hundreds of thousands, millions, in fact, a lot of imported equipment, we can repair it ourselves." Chen Yu said endlessly.

"Won't it?" Wang Zhengxin was suddenly a little dumbfounded.

"How not? Foreigners sell equipment to us, almost all have to sign a contract, most of the contracts, require that if the equipment is broken, our people cannot repair it themselves, and must ask them foreigners to repair it. Chen Yu said.

The situation of Azure Star is very similar to that of the earth for more than nine years, and in the Great Han Kingdom of this era, many high-tech equipment were imported from the gringos, and for the sake of technological blockade, there were many overlord clauses.

"Two, our factory director agreed, as long as you repair this machine tool, we will give you 8,000 yuan." Li Dazhu walked over quickly, if there wasn't an order in a hurry, they wouldn't have looked for someone outside to repair it.

"There is no evidence, before repairing this machine tool, we will sign a contract, in case you don't give us money after this machine tool is repaired, then we will lose a lot?" Chen Yu said indifferently.

"How long will it take you to fix this machine?" Li Dazhu asked.
