On the official first day of school, the first class, the amphitheatre, which could accommodate hundreds of people, was full. Not a single student skipped class. Countless students held books in their hands and stared at the figure on the podium with burning eyes.
Lin Guohua, a master in mechanical engineering, is over sixty years old and at his level does not need to teach ordinary undergraduates, but this year is different. This is the first academic year when the college entrance examination is resumed.
Looking at the countless pairs of hungry eyes in the audience, the passionate pride burst out from his old body.
These students are hope!
"Ahem!"
"Students, please put down the books in your hands. Today is the first class. Before the teaching begins, let's talk about why you want to go to college?"
“Why should I apply for the mechanical engineering major?”
Lin Guohua did not give the students a chance to answer the questions. After saying these words, he picked up a piece of chalk, stood on the three-foot podium, and wrote a few big characters with a few strokes.
Read for the rise of China!
"These words were taught to me by my teacher. I still remember that it was the winter of 1938. What happened in 1937, I believe I don't need to say anything more."
"The Japanese invaders have fully invaded China, and the smoke-filled north can no longer accommodate a quiet desk!"
"but!"
The gray-haired old professor suddenly raised his tone and straightened his slightly rickety body.
"If a country dies, it can be revived; if a culture dies, it will all perish!"
"At that time, my teachers and classmates and I had to move again and again, from the capital to Shonan, and from Shonan to Spring City. After traveling thousands of miles and traveling to many places, we finally found a temporary place to live."
"After arriving in Spring City, we had no houses, so we built them ourselves, and no food, so we grew them ourselves."
"It's normal to not have enough to eat, not to wear warm clothes, and not to have good housing. You may not believe it, but Professor Liang and Mr. Lin personally designed the place where we live."
Having said this, the old professor smiled, as if he was caught in memories, and his tone paused slightly.
"Professor Liang and Mr. Lin are both great architects, but the house we live in is probably the simplest house they designed, with thatched roof, yellow mud walls, and 40 beds in one room."
"When it rains, a symphony of tinkling-ding-dong-dong is heard in the classroom. It is the sound of raindrops colliding with pots and pans. Every time I think of it, that sound still seems to linger in my ears."
"At night, mosquitoes will also sing a song for us. From night to dawn, they 'sing' for us tirelessly."
"Oh, by the way, occasionally the Japanese troops would blast cannon fire to congratulate us."
The old professor's voice was not loud and his tone was calm, but it struck everyone's hearts like a heavy hammer.
"Students, I am telling you this today not to tell you how miserable we are, but to tell you!"
"Why should we study?"
"Because we are lagging behind, we will be beaten if we fall behind!"
"Although war seems far away from us, there is more than one form of war. Technology is also a battlefield without smoke!"
“Last month, at the just-convened National Technology Conference, the Vice Prime Minister emphasized that ‘science and technology are productivity’!”
“If you want to realize the four modernizations, you cannot do without science and technology!”
"The world is yours and ours, but in the final analysis it is yours. The teacher is old, and you are the sun at eight or nine o'clock. The rise of the country in the future will ultimately depend on you!"
Bang! Bang! Bang!
The scene suddenly erupted into thunderous applause. The old professor’s earnest teachings made countless students’ blood boil, and many students’ eyes were soaked with tears.
The old professor saw the light in the students' eyes and smiled happily. He lowered his hands slightly to signal everyone to be quiet.
In an instant, the roar of applause gradually stopped.
"I just mentioned the first question, why should we go to college? Now let's talk about why we should study mechanical engineering."
"A modern country cannot develop without industry. Everything from airplanes, tanks, cannons to a tiny screw cannot do without the development of industry!"
“And what is the mother of industry?”
The old professor turned around and wrote two more words on the blackboard.
machine tool!
"Many of the students in the audience must have been in factories. The lathes, milling machines, boring machines, etc. in the workshop are all industrial machines. As the name suggests, they are machine tools used to manufacture machines and machinery!"
"The industrial mother machine manufactures various types of machinery and equipment for all walks of life. It is the heart of modern industry, the cornerstone of the industrial system, the cradle, the core, and the symbol that determines the level of national industrial development!"
"To put it bluntly, there is at least two generations difference between our country's machine tool development level and that of developed countries, and it lags behind by decades!"
"Even if there is an advanced machine tool out there and we can study it at will, we will not be able to build a machine tool with the same accuracy and stability!"
"why is that?"
"Because manufacturing is never a single industry, it considers the overall basic industrial level of a country."
"To give a simple example, last year, the First Machinery Factory built a 12-cubic-meter excavator. Every part in it was produced independently by us."
"Although everything is the same, our excavators are not as good as imported ones. The working hours, parts usage tasks, and stability all lag behind imported products."
"why is that?"
"Because the accuracy and stability of our parts are not as good as imported parts!"
"Why not?"
"Because the machine tools we use to produce parts are not as good as those in developed countries. The same thing we produce can only be used for a hundred hours under full load, while foreign parts can be stably used for hundreds of hours.
Thousands of hours!”
"Students, the teacher is not saying this to tell you how good and powerful foreign products are, but to tell you that there is a huge gap between our industrial level and foreign countries."
"Only by understanding the gap and knowing where we are falling short can we catch up."
"I believe that one day we will be able to catch up with the West!"
"Why do I believe so strongly?"
"Because we were able to develop the atomic bomb, the hydrogen bomb, and the Dongfanghong No. 1 with nothing but nothing!"
"We could do it back then, but now that the conditions are better, there's no reason why we can't do it!"
"It's a pity that the teacher is old and probably won't see that day anymore, but you are still young and you still have a chance!"
"The future is in your hands!"
Jingle bell bell!
The bell rang for the end of get out of class, and the old professor took a deep breath and shouted.
"get out of class is over!"
Bang! Bang! Bang!
The applause from the scene came like a tidal wave and lasted for a long time. The students clapped their already red hands excitedly.
