78: Bringing his wife and children to Harbin Institute of Technology

"Can you get in touch with me?"

"I'll send someone to deliver the message."

Liu Yongqiang said.

"But you have to prepare the motor parameters and test data. They need to see the real thing before deciding whether to help or not."

"no problem."

Ye Bingwen said.

"I'll send the materials over first thing tomorrow morning."

After hanging up the phone, Ye Bingwen began searching for documents in his office.

He found all the test data from the first prototype to the most recent batch of military products and organized them in chronological order.

Every data point has an original record, and every curve has a measured point.

He spent an afternoon organizing these things into a decent document, made three copies with carbon paper, and bound them together.

As darkness fell, he returned to the faculty dormitory.

An'an is awake and is sitting on a small stool stacking blocks.

"dad!"

Ye Bingwen bent down and picked her up.

An'an patted his face with her little hand.

Zheng Shuyun is cooking in front of the stove.

"You're back? Dinner will be ready soon."

An'an reached for a plate of peanuts on the table, but he gently stopped her.

"Eat rice first, then peanuts."

An'an started playing with the buttons on Ye Bingwen's work clothes pockets.

Dinner was stir-fried cabbage with sliced ​​pork, served with cornbread.

Zheng Shuyun's cooking skills are getting better and better.

When Ye Bingwen was eating his third steamed bun, Zheng Shuyun asked him a question.

"Any progress on the quality inspection issue?"

"Liu Yongqiang found an experienced expert; he'll deliver the materials tomorrow."

"Will it work?"

"It's hard to say."

Ye Bingwen picked up the enamel mug and took a sip of water.

"But we should always give it a try."

An'an fell asleep on his lap.

Ye Bingwen looked down at her, and the tension in his heart slowly eased a little.

The next morning, Ye Bingwen arrived at the family compound of the Provincial Mechanical Research Institute.

The building is a Soviet-style red brick building constructed in the 1950s.

Liu Yongqiang was waiting for him at the entrance of the building.

"He's on the third floor, and his legs aren't very strong. Let's go upstairs."

The two climbed to the third floor, and Liu Yongqiang knocked on the door.

The door opened, and an elderly man with gray hair appeared in the doorway.

"Engineer Hu, this is Ye Bingwen, the one I told you about."

Liu Yongqiang explained.

Hu Guangzhi glanced at Ye Bingwen.

"Are you the college graduate who started his own factory?"

"It's me, Engineer Hu."

"Come in."

The living room wasn't big, but it was very clean.

Along the wall is a row of bookshelves, almost all of which are technical books—"Electrical Machines," "Vibration Theory," "Mechanical Design Handbook," etc.

Hu Guangzhi sat down in the rattan chair and pointed to the wooden stool opposite him.

Ye Bingwen handed over the materials.

"Mr. Hu, these are the basic parameters of the motor and all the test data. Please take a look."

Hu Guangzhi put on his reading glasses and turned to the first page.

The living room fell silent.

The only sound was the turning of pages.

Hu Guangzhi reads very slowly, sometimes lingering on a single page for a long time, as if he were doing mental calculations.

Ye Bingwen sat on a wooden stool.

About twenty minutes later, Hu Guangzhi turned to the page on vibration testing and suddenly stopped.

He raised his head.

"Did you measure this vibration data yourself?"

"Yes."

"What was used to measure it?"

Ye Bingwen explained the testing method in detail.

After listening, Hu Guangzhi looked at the data page again.

"Your level of vibration control is even better than the projects I worked on before I retired."

He looked at Ye Bingwen.

"How did you manage that, a student who didn't even graduate from university?"

Ye Bingwen had already thought about how to answer this question before he came.

"It's not really an experiment."

Ye Bingwen told the truth.

"The problem is that the old machine tool always produces defective products when doing precision work. I measured the vibration data several times."

"We discovered that it matched the natural frequency of the foundation, confirming it was a resonance issue."

"Later, we changed the foundation design and adjusted the dynamic balance of the rotor, and the vibration decreased."

Hu Guangzhi did not ask any further questions.

"I've reviewed the data."

Hu Guangzhi closed the materials and leaned back in his rattan chair.

"What do you want me to do?"

"The provincial authorities are coming for quality inspection the day after tomorrow. I need a third-party technical assessment report."

Ye Bingwen said.

"It's not a replacement for official quality inspection, but a backup. If there's a problem with the quality inspection report, I'll have something to show for it."

"You suspect that the provincial quality inspection is unfair?"

"I'm not sure, but I want to be prepared."

Hu Guangzhi tapped his fingers lightly on the armrest of the rattan chair.

"I've checked your motor, and according to the specifications, there's no problem."

He spoke slowly.

"It's better than the products from many factories in the province. I can write a report, but I have one condition."

"Please speak."

"I don't take sides. My report only states the facts I see; good is good, and bad is bad."

"If there's a problem with your motor, I'll write it down truthfully."

Ye Bingwen nodded.

"Of course."

"besides,"

Hu Guangzhi pointed to the materials.

"Leave this document with me; I need to review it again. Come pick up the report tomorrow afternoon."

Ye Bingwen stood up and bowed.

"Thank you, Engineer Hu."

When I stepped out of the apartment building, the wind had picked up a bit.

Liu Yongqiang glanced at Ye Bingwen.

Do you think he's reliable?

Ye Bingwen thought for a moment.

"He's reliable. These kinds of veteran experts have made a living through their skills their whole lives; they wouldn't use their reputation as a tool for others."

"Whatever he says goes, without bias or deviation."

"That's good."

Liu Yongqiang handed the bicycle to him.

"Don't worry about the approval, I'll try to find out more for you."

The next afternoon, Ye Bingwen appeared at Hu Guangzhi's door on time.

Hu Guangzhi handed him the report, in which every data point was labeled with its source and every conclusion was supported by evidence.

The last paragraph of the report reads.

"Upon review, all performance indicators of the motor meet or exceed the relevant national standards."

"The vibration control level is among the most advanced in similar products. This is hereby certified."

The document was signed by Hu Guangzhi himself, dated, and stamped with his personal seal.

Ye Bingwen put the report into his inner jacket pocket.

"Engineer Hu, I will make good use of this report."

Hu Guangzhi waved his hand.

"Go."

As Ye Bingwen reached the door, he heard Hu Guangzhi's voice behind him.

"Xiao Ye, do a good job with this motor. Our country is striving for the Four Modernizations, and what we lack most is this kind of genuine talent."

"I've got it."

He got on his bicycle and headed towards the motor factory.

The quality inspector from the provincial department will be arriving tomorrow.

He is ready.

Early in the morning, a jeep from the Provincial Department of Industry arrived at the gate of the motor factory.

When Ye Bingwen arrived, the car was already parked there.

Mr. Li had an unlit cigarette between his fingers, and his expression was not good.

"You're here?"

Ye Bingwen went over and asked.

"They're here."

Master Li gestured with his lip towards the jeep.

"Two people arrived. One was surnamed Gu, and he said he was from the quality inspection department."

"There was another person surnamed Ma, from the Provincial Department of Economic Management, who said he was there to 'cooperate with the work'."
