Go back in time and be a chaebol

Chapter 545: A flash of inspiration (Third update, please subscribe)
During the rainy season, it always rains non-stop. Sometimes, the rain comes and goes quickly. Sometimes it rains continuously and pours.

If it weren't for the construction of sewers in the city that can withstand typhoon-level heavy rainfall, a heavy rain in the rainy season would probably turn the city into Venice. Although there is no accumulation of water on the ground, people hurriedly carrying umbrellas will inevitably get wet. Some people who did not bring an umbrella were unlucky. Even if they hurried to the bus stop with a briefcase on their heads, they would inevitably get soaked.

After the bus entered the station, people got on the bus one after another and looked at the heavy rain outside the bus. The wet passengers looked a little embarrassed.

"I'm sorry, I'm sorry, I was in a hurry this morning and forgot to bring an umbrella."

"I can forget this. It's rainy season. It won't rain that day."

"you do not say."

In the sound of your words and my words, the man explained.

"Hey, umbrellas are usually hung at the door, but I never thought that I forgot to take them. You said it would be great if the umbrella could be put into the briefcase, so I wouldn't forget it."

As soon as the man finished speaking, someone said next to him.

"Isn't the two-fold umbrella quite compact?"

work overtime.

In the next few hours, Zhao Hai lay on the desk studying how to realize the three-fold fold of the umbrella.

Zhao Hai, who only studied engineering college, never thought of himself as an inventor. He was just the most ordinary technician in an umbrella company.

"Three folds... doesn't seem difficult?"

But he knows a lot about umbrellas. Although a two-fold umbrella is smaller than an ordinary umbrella, it is still 55 centimeters long. If it is a three-fold umbrella, it can be placed in a briefcase.

……

"Two folds means a "V", and three folds means folding again..."

Immediately, the Ministry of Labor began to implement a system that prohibited employees from working overtime after 8 p.m. Supervisory officials will also be dispatched, and if found, companies will be severely punished.

Maybe it sounded like a joke to others, but when Zhao Hai heard this sentence, an idea flashed in his mind.

With the prosperity of the industry, it is almost inevitable, especially for new employees.

Looking at the two-fold umbrella in his hand, Zhao Hai thought in his heart.

After returning to the apartment, Zhao Hai got busy on the desk, studying the two-fold umbrella and imagining the "three-fold" of the three-fold umbrella.

"Then let's make a few more folds. We already have two folds. It's not difficult to fold it again!"

“How can such a small umbrella keep out the rain?”

According to statistics from the Ministry of Labor, the average working time during the Nanyang Week last year was 48.5 hours. So much so that the Ministry of Labor issued a warning that frequent overtime work will not only affect social consumption, but also affect social fertility.

Work overtime. Sometimes, people will always take the initiative to work overtime, not for the company, but for interest, or a flash of inspiration in their mind.

Fold it again!
Tri-fold umbrella?

"The two-fold umbrella is still too long and can't fit in. It should be half smaller."

Therefore, eight o'clock has become the last time for companies to get off work.

Li Qinglong left the company on time at eight o'clock and returned home at eight forty. Like most single employees, he, Li Qinglong, also lived in an apartment.

Climbing the stairs to the third floor, I opened my door. The bachelor apartment is not spacious, but it is definitely not cramped. The apartment has five rooms: a living room, a bedroom, a bathroom, a small kitchen, and a small room filled with miscellaneous items. This type of apartment is a mass-built national apartment based on standardized drawings. Most single employees live in such apartments - most workers live in collective dormitories.

After graduating from Nanyang University, he moved in. In the simply decorated room, an old photo hung. It was a family photo taken in a photo studio with the family when Li Qinglong left his hometown four years ago. A family stands in front of a photo studio backdrop. Father and mother stood in front, and their five brothers and sisters stood behind them.

Since then, this photo has been with him. After moving to the apartment, he kept this photo there and it became all he missed about his family.

After taking a look at the photo, Li Qinglong said to himself.

"Mom, don't worry, everything is fine with me here..."

Afterwards, Li Qinglong took out the information from his briefcase and continued working as usual. He may not be able to work overtime at the company, but he can still work overtime when he returns home.

Since you have nothing to do anyway, you can understand the pain of homesickness by working overtime.

Until late at night, Li Qinglong, who was still sleepy, had to turn on the radio to listen to some music. He turned the knob of the radio and was surprised to find that the radio was playing Beethoven's "Ninth Symphony" played by the Philharmonic Orchestra.

As a music lover himself, he was naturally fascinated by the music, but he soon discovered a blind spot:
"Why is this sound so...refreshing?"

After looking at the alarm clock, Li Qinglong said to himself.

"It's 2 o'clock in the morning! The Philharmonic Orchestra has long since rested; but it seems that this is not a recording! A 16-inch wax tape cannot record such an excellent sound!"

Strange, really strange. Could it be that Nanyang Broadcasting Station has some kind of high technology?

……

A few days later, Li Qinglong made a special trip to Nanyang Radio Station and finally solved his doubts.

"We use magnetic tape. This technology was invented by Germany before the war."

"Tape? What's a tape?"

With the radio station technician's explanation, Li Qinglong finally understood what a tape was.

"Before the war, German inventors applied magnetic iron powder to paper tape to record sounds. Later, it was improved to use cellulose acetate foil as the carrier material, coated with iron oxide paint as the magnetic material, and cellulose acetate as the adhesive. Agent, this kind of tape is played by a magnetic listening machine..."

During the radio station technician's explanation, Li Qinglong finally figured out the working principle of the tape and the magnetic hearing machine. At his request, the technician played a few songs on the magnetic hearing machine, which was about the size of a freezer. He was shocked that he could barely hear the difference between playing live and recording.

"Tape, tape..."

When leaving the radio station, Li Qinglong had only one idea left in his mind - to develop better magnetic hearing machines and tapes.

"Can you improve this thing?"

Thinking about the machine that was as big as a freezer and the large tapes it played, Li Qinglong subconsciously thought of starting with shrinking the tapes.

"The magnetic hearing machine should be smaller, like, like...the size of a radio. First make the tape smaller."

Although Li Qinglong was an outsider, as an engineer, after making up his mind, he immediately jumped into the research of magnetic hearing machines and found the corresponding technical information from the library - thanks to Germany's defeat, after the war, Germany was attacked by the Allied forces. As a result of various liquidations, many patents held in pre-war Germany fell directly into the public domain and can be easily found in libraries.

In fact, even the magnetic listening machines of radio stations were improved and manufactured using those public patents.

Sometimes, many inventions are based on a flash of inspiration. The rest is the accumulation of time and sweat. This process is even full of twists and turns, and there are almost no shortcuts.

It was another sleepless night. When the morning sun rose again, Li Qinglong, who had been studying tapes and magnetic recorders all night, looked out the window. Although the window was full of clouds, his face was full of smiles. This has always been the case, as long as you find your goal, there will always be changes from the inside out.
