After hearing what Chen Lidong said, the security guard retorted: "Young man, are you the driver? Who told you that we were under investigation?"

Chen Lidong murmured: "We came here from the west urban area, and when we were at another steel sales company, they said that Dingsheng Steel Trading was inspected by the quality inspection department.

I just saw the sign at the door, you are here Dingsheng Steel Trading."

The security guard said: "Don't worry, someone came to check a few days ago, but what does our boss have to do with us?

Little brother, just drive well for the boss and don't make any trouble, you know?"

Chen Lidong continued: "You must tell your boss, but what if there is a problem with the steel? If we buy the steel and get scammed, we will have to deal with it at the factory."

Wu Weiguo took over: "Xiao Chen, please go out first. I'll have a chat with my brother."

When Chen Lidong walked out of the duty room, Wu Weiguo took out a banknote and handed it to the security guard: "Brother, you have to tell me whether there is anything wrong with your steel..."

Chen Lidong came outside, took out his keys, opened the car door, and sat in the driver's seat.

After waiting for a few minutes, Wu Weiguo came out and sat in the passenger seat.

Chen Lidong asked: "What did the security guard say?"

Wu Weiguo shook his head and said: "The security guard said that four or five days ago, someone with a big cap came to check the warehouse.

Their boss happened to be here and took those few people to dinner at noon.

Then the day before yesterday, his boss told people that the incident was over and everything was fine.

His knowledge of the situation is limited, and he cannot explain why he is so ugly, and a hundred yuan is wasted."

Chen Lidong said: "It's not in vain, Brother Angkor has worked hard."

Then I started the car, drove for a while, and stopped on the side of the road.

After another half hour, Edmund followed. Chen Lidong got out of the car and Edmund drove.

After returning to the room, Chen Lidong asked Edmund, "Have you found our steel?"

"We have it in the warehouse, the brand number is q345b, 15.6 tons."

"Did you find any evidence?"

"I found the outbound record sheet in their financial office. There are a total of 6 records of q345b on the list. I will write it down for you."

Edmund took a pen and paper from the desk nearby and wrote down the sales records of Donghua Steel line by line.

Chen Lidong took it, looked at it, took the pen, calculated on the paper, and said:

"There is a problem. They purchased 500 tons of q345b from our factory. The total of these 6 transactions is 395 tons. You said there are still 15.6 tons in the library, which is a difference of 89.4 tons.

You can check again and see if there is any record of about 90 tons in their outbound records."

Edmund said: "In my database, since November last year, there are only these 6 records of q345b being shipped out of the warehouse."

"Check whether other brands of steel have been shipped." Chen Lidong asked.

"I found it. On November 22, there was a shipment record of 90 tons, and the grade was hg70c." Edmund said.

Chen Lidong picked up the phone and dialed his brother: "Brother, I'm in the hotel in Quancheng... Well, I'll go to the General Administration of Quality Supervision tomorrow... Brother, do we produce hg70c grade steel?"

"Hmm, then what's the difference between these two grades of steel?...Oh...I see...It's a bit of a clue. You can rest first and we'll check it out tomorrow."

Putting down the phone, Chen Lidong chuckled.

Chen Lichun told him: hg70c grade steel is a high-strength welded structural steel and a special steel plate for hydraulic supports.

Compared with q345b, hg70c has higher yield strength and tensile strength, and the price difference between the two is nearly a thousand yuan!

Chen Lichun said that Donghua Iron and Steel has never produced steel of the grade hg70c! This kind of steel is only produced by a few steel plants such as Baogang, Beigang, Anyang, and Taigang.

Chen Lidong suddenly understood. He had concluded that Dingsheng Steel Trading had faked the product and sold Q345b as hg70c to a machinery company. The machinery company did not test the performance of the steel, so it processed it into a load-bearing cylinder and sold it to a hydraulic company in southern Gansu.

Reason for cheating?

The price difference of one ton is 1,000! 90 tons is 90,000 yuan. At this time, 90,000 yuan can buy a two-bedroom apartment in the center of Quancheng City.

Moreover, the properties of the two steels are similar. For example, if hg70c is real cowhide and q345b is simulated leather, both can be made into bags. Most people without professional inspection will not be able to tell, but they can be made into sports shoes and run 50 meters.

q345b will crack.

It should be that the hydraulic company used the cylinders from the machinery factory in heavy machinery equipment. When an accident occurred, they realized that the wrong steel was used and started to investigate.

Haha, Chen Lidong secretly gritted his teeth: Dingsheng Trading can do this, and can spread this kind of sewage to Donghua Steel!

The next day, Wang Jiaqi appeared at the Shandong Provincial General Administration of Quality Supervision, as a lawyer, and Zhou Wenliang, as a reporter for the monthly "East China Machinery" magazine:

On behalf of Donghua Steel, Wang Jiaqi filed an administrative review against the law enforcement actions of the General Administration of Quality Supervision, and requested to meet with the company's legal representative Yin Fumao.

Zhou Wenliang, on behalf of the "customer groups who are worried about being harmed by Donghua", proposed to interview law enforcement officials to disclose to the public the incident of Donghua Steel's "falsification and passing off quality products" to prevent more people from being deceived.

Regarding Wang Jiaqi's request, the General Administration of Quality Supervision only left his appeal application.

Zhou Wenliang, on the other hand, arranged for the head of the law enforcement brigade to receive him and be interviewed.

Asked about the progress of the investigation, the deputy captain named Zhang Zhigang said: "We are still collecting additional evidence. Our Shandong Province Quality Supervision System will definitely crack down on companies that commit fraud and pass off substandard products and will never be lenient."

Zhou Wenliang gave the other party an appreciative look and continued to ask: "Team Zhang, you are an expert in quality inspection. Can you do some popular science for me?"

Zhang Zhigang smiled and said: "Reporter Zhou, what question do you want to ask?"

"That's right. Many of the readers of "East China Machinery" are manufacturers of mechanical processing, and they attach great importance to the quality of steel.

People called me and were very angry about Donghua Steel's fraud and shoddy behavior.

They really want to know what kind of fraud Donghua Steel uses to defraud customers."

Zhang Zhigang said: "Then I will explain the specific circumstances of this case to readers in detail.

We have Hongsheng Machinery Co., Ltd. in Quancheng, which is an old machining company. They purchased a batch of steel from Donghua to produce hydraulic cylinders. The hydraulic cylinders they produced were sold to Gannan Hydraulic Company for parts.

The grade of this batch of steel was hg70c, but after subsequent testing, it was found that the performance of Donghua's steel failed to meet the national standards, which directly led to the failure of the hydraulic cylinder.

Gannan Hydraulic Company demanded all returns and compensation for losses, causing a direct loss of 400,000 yuan to Hongsheng Machinery, and the loss of reputation was immeasurable.

Hongsheng Machinery is a supplier to many high-end equipment manufacturing companies such as Lunan Heavy Machinery. Because of this incident, they are likely to be disqualified from supplying goods.

Hongsheng Machinery is a key enterprise in Quancheng and well-known in Shandong Province.

Our bureau went to your blue city to enforce the law just to safeguard the image and interests of key enterprises in Shandong Province."

Zhou Wenliang asked: "Team Zhang, is hg70c grade steel common in the market?"

Zhang Zhigang continued to speak in the tone of expert science popularization: "HG70 series plates should belong to a special type of steel. Our quality inspection office below has some information, but the law enforcement brigade is not very clear about it."

Zhou Wenliang continued to ask Zhang Zhigang, "Team Zhang, do you think someone may have counterfeited the factory logo of Donghua Iron and Steel?"

Zhang Zhigang's face froze, "This... can't be true."

Zhou Wenliang opened his notebook and said: "Team Zhang, our magazine reporter interviewed Donghua Steel yesterday, and Donghua stated:

They have never produced hg70 series plates, let alone fake or pass them off as quality products;

Donghua also said that the only steel they sold to Quancheng was a batch of 500 tons of q345b plates. Are you sure that this batch of hg70c was produced in Donghua?"

Zhang Zhigang hesitated and said: "Comrades in the team have verified the remaining steel from Hongsheng Machinery Factory. The factory logo is Donghua Steel, and the brand mark is also hg70c."

Zhou Wenliang continued to ask: "Team Zhang, do you know the company Dingsheng Steel Trading Company?

Donghua Steel said: This batch of 500 tons of q345b steel plates was sold to Dingsheng Steel Trading Company and has no trading relationship with Hongsheng Machinery.

Have our law enforcement comrades investigated Dingsheng Steel Trading Company?"

Zhang Zhigang stopped talking.

But Zhou Wenliang did not give up: "Team Zhang, there is a purchase and sale contract between Donghua Steel and Dingsheng Steel Trading, which can be verified;

It is not difficult to verify the source of the steel plates purchased by Hongsheng Machinery. Is there some link in the process that was not investigated clearly?"

Zhang Zhigang stood up and said: "Reporter Zhou, I have other things to do, so I'll get here first."

After saying that, he turned around and left the reception room.

Wang Jiaqi and Zhou Wenliang returned to the hotel where they were stationed and reported to Chen Lidong on their trip to the General Administration of Quality Supervision.

Before noon, Chen Lidong received a call from Yin Fumao, saying that he was released.

After everyone met, Yin Fumao just felt a little haggard.

So Chen Lidong, Wang Jiaqi, Zhou Wenliang and others worked together to cleanse Yin Fumao.

Yin Fumao said: "They dropped me off at the hotel the day before yesterday and no one paid any attention to me. I must have been on a business trip out of nowhere."

Wang Jiaqi asked: "Didn't the other party make a record for you?"

"No, I gave them paper and pen yesterday morning, but no one answered me after that."

Chen Lidong smiled and said, "It seems that their case investigators knew something was wrong a long time ago, but someone in the middle was covering the lid.

If Donghua was a small factory, it might be cleaned up."

Wu Weiguo said: "It has something to do with Dingsheng Steel Trading. They have a foundation in Quancheng, and they may have bribed the people below. If we can let us take the blame, they can get out."

At this moment, Wu Weiguo's phone rang. He answered it for a while, then covered the phone and said, "The boss of Dingsheng Steel Trading said he wanted to see us."

Chen Lidong said: "Just hang up, I won't see anyone. We are unfamiliar with the place and we will suffer a loss if we meet them."
