Seeing that the store is becoming more and more mature, and many large enterprises in many places have entered the store, Yao Xinyi, the boss of DunAn Group, decided to put his own empty withering hardware accessories factory in the store, so the arrival of DunAn has added greater vitality to the store.

When DunAn first came, it was just making air conditioning accessories, and I didn't expect that a few years later, it would become a group company.

The development of small hardware in the store has basically been perfected, plus DunAn has brought air conditioning technology to the store, which has enriched the development of refrigeration in the store, as soon as the stop valve factory of DunAn settled in the store, someone learned to make air conditioning accessories, and passed the technology out, what condenser, condenser tube, globe valve, two valve cores, three valve cores and other technologies have been learned by the people of the store.

Japan has been in 1986 in the big city of Shenzhen air conditioning, at that time are air refrigeration, the use of two-spool technology, through the Freon R series to send air out of the air conditioner, the use of Freon refrigeration technology has been relatively mature. Through the closing effect of the shut-off valve, the freon is allowed to function in the condenser, and the cold air is blown out to become a condensing technology. The previous water-cooled and air-cooled technologies became history, and finally the world agreed that condensing technology was the most reliable, and Japanese air conditioners were recognized and promoted by countries around the world.

Beginning in 1984, China Haier also tends to study air conditioning technology, through several years of technical research, finally succeeded, later Haier air conditioning, became a world famous trademark, Haier Group use three-core globe valve, so that the cold air of the air conditioner is more powerful, in the condensation time and power consumption far better than the two-core globe valve, in the globe valve to win the air conditioning war. There is a big difference between the air conditioning shut-off valve, the three-way and the two-way, and Haier also adopts nitrogen-filled anti-oxidation technology on the condenser pipe, which greatly increases the service life of the air conditioner, which makes many air conditioning factories have been lagging behind.

If it weren't for Gree air conditioner using the world's advanced centrifugal technology, then Haier would still be far ahead in the air conditioning industry. With centrifugal technology, the power loss of the air conditioner is greatly reduced, so that the air conditioner has more than 20 kilowatt-hours of electricity per day, and it has become three or two kilowatt-hours of electricity, and this technology has to lead the world.

As soon as Dun'an came to the store, within a few months, the air-conditioning products he produced sold well and became a leader in the air-conditioning industry, Yao Xinyi saw that the air-conditioning accessories in the store were so good, so he increased his investment, and simply bought a street in the store, and built various branches of Dun'an, at that time, Dun'an's factory was the largest, and the house was built big, the workshop looked particularly majestic and tall, with a silver-gray exterior wall, and he knew that it was Dun'an Street from afar.

At that time, the company mainly produced precision manufacturing of refrigeration parts, valves, and fluid control components. Later, after the development of technology in 2007, the development of large-scale heating and ventilation system equipment, motors, heavy machinery and other high-end equipment R & D and manufacturing, the industry under the jurisdiction of DunAn Environment, DunAn Intelligent Control, DunAn Electric, DunAn Seiko and other companies.

DunAn Environment: It is a leading enterprise in the global refrigeration accessories industry, the first enterprise in China to produce nuclear-grade chillers for nuclear power plants and has independent intellectual property rights, and one of the most influential energy-saving service brands in China.

DunAn Intelligent Control: Huayi Precision Machinery, which is an industrial group specializing in the research and development and manufacturing of valve products under DunAn, is a leading enterprise in China's valve industry and one of the top ten well-known brands in China's valve industry.

DunAn Electric: Xi'an DunAn Electric Co., Ltd., established in October 2007, is mainly engaged in the research and development, manufacturing and technical services of wind turbines, high-voltage motors, oilfield motors and other fields of motors and electronic controls.

DunAn Seiko: Zhejiang DunAn Light Alloy Technology Co., Ltd., Xuzhou DunAn Heavy Industry Machinery Manufacturing Co., Ltd. and other enterprises are concentrated in the vicinity of construction machinery and light alloy parts manufacturing.

There is not much to say about civil explosive chemicals, new energy, new materials, investment management, modern agriculture, etc. He is one of the three Fortune 500 companies in Diankou, and two are VIE Group and Hailiang Group.

As soon as this shield came, several refrigeration companies appeared.

This Dun'an settled in the store, it is simply thriving, and it has grown in less than a year, which Han Sanjiang didn't expect, so he asked Mu Chunfeng: "You said that this Dun'an came to our store to develop so rapidly, look at the momentum to catch up with Wan'an, this guy is coming vigorously?"

Mu Chunfeng smiled and said: "It seems that our store is going to become a leading enterprise, which is a good thing, with DunAn, the development speed of our store will be accelerated!"

Jiang Yuanqiao said: "This Dun'an is here, maybe, there are other big companies also come to our store, this is a matter of time, you see, our store is booming, just right Han Dajiang's sentence, saying that our store will go out of the store in ten years and become a business card of Zhejiang, this is right." In less than five years, we have more than 1,000 medium-sized enterprises and more than 2,000 small processing factories in our store, and the annual income has reached hundreds of millions!"

Mu Chunfeng sighed and said: "It's a pity that Dajiang Group has developed in other places, Dajiang Construction Engineering has subsidiaries all over Zhejiang, as well as several cement factories, he has already walked out of the store and has become a veritable big man!"

Han Sanjiang replied with a smile: "No matter how he goes out, it is also our store, the root is in the store, of course, I hope everyone will also go out, there are too few places in the store, and the subsidiaries will be built in the provinces, it will be better, our store will not be able to fit these large group companies in the future, only go out, that is indeed to give our store a fight!"

Jiang Yuanqiao said: "Old Han, we have changed from young men in our twenties to middle-aged people in our thirties, and our children are about to enter kindergarten, but this change is indeed so fast that even we can't react! In another ten years, I think we will withdraw from the stage and let capable young people take over us! At that time, we don't know how many doctoral students and graduate students will appear in our store? We college students have such a big macrocosm in our hands, and we can't understand it!"

Han Sanjiang took a sip of tea and shouted: "By the way, I haven't seen Ziyan girl for a few days, where has she gone?"

Mu Chunfeng smiled and replied: "That girl came to me, I didn't pay much attention to her, she said that I was biased, saying why I used Zhang Xiaoying as a matchmaker and didn't use her as a matchmaker, she couldn't figure it out, so I said, then you go back and think about it, come to me again when you figure it out, I'll wait, I can't run, hehe, this girl is really gone, maybe go back to think about the problem, and she will come to me when she figure it out!"

Jiang Yuanqiao smiled and replied: "Lao Mu, you are wrong, that girl pestered my wife Chunjiao and asked her to find her mother-in-law's house, do you think she still comes to you, she has a lot of flowers?"

Han Sanjiang asked, "Then did your wife Chunjiao help her find a partner?"

"Well, I've found it!" Jiang Yuanqiao replied.

"Who?" asked Mu Chunfeng and Han Sanjiang at the same time.

"Liu Chunming!" Jiang Yuan replied.

"Why is it my apprentice?" Han Sanjiang couldn't help but ask.

"Hehe, that girl said that she likes to find Lao Han's apprentices, Lao Han's apprentices are all handsome! Why are you unhappy Lao Han?" Jiang Yuanqiao couldn't help but ask when he saw Han Sanjiang with a poker face.

"No, Liu Chunming's guy, although he looks good, he just loves to be lazy, you see that everyone is getting rich, and he is still like that, looking at him, Lao Tzu is angry, such a person is better to fight a single for the rest of his life, and there is nothing that has grown!" Han Sanjiang originally hated iron but not steel.

"Maybe he will be more diligent after he begs his wife?

"Hehe, I hope so, the dog can't change the problem of eating, he's lazy, can't get on the road, and even a shopkeeper can't look down on him, but that guy doesn't know it, if he is diligent, it's really the sun coming out in the west!" Han Sanjiang sighed and said.
