296 Chapter 290

January 20, 1991.

United States

Hao Yunli took a day off and left for the airport at 7:30 in the morning. She had to catch a United Airlines flight to Irvine in the Bay Area. Zhao Mengjia and Yuan Shuai had been there for a few days.

Because of the time difference, it was still morning here after Hao Yunli arrived.Take the airport bus and then change to the urban BUS, all the way tossing, when it comes to school, it is already noon.

Hao Yunli is reluctant to take a taxi. Every time she travels, she mainly uses the subway and BUS.

When I got off the BUS station, I saw Yuan Shuai sitting under the stop sign.

Hao Yunli greeted her excitedly and hugged each other.Yuan Shuai's right hand stretched out stiffly in the air, unable to move.After the female classmate released her hand, she turned her head and said with a smile,

"Which country's etiquette are you? There are none in the training abroad."

"This is Chinese etiquette, only for classmates."

Hao Yunli was excited. It took almost half a year to see her classmates, real acquaintances.After seeing Zhao Mengjia, the two of them jumped and jumped, and it took a long time to calm down.

————————

It's noon, everyone rushed to the cafeteria. The food in the cafeteria of the University of California is also well-known in the United States.

"Yuan Shuai, I have seen your published papers. They are very well written. I showed them to our laboratory colleagues. They are very envious."

Everyone walked and talked.

"Yes. But Cheng Yongxing has always been doing the main experiment. I'm doing miscellaneous work. Because I'm more diligent, he remembered a second one for me."

"Just be humble. How do you feel when you come here? It seems to be much warmer than Pittsburgh."

"Yeah, it's so warm here, it's totally incomparable with Bingcheng."

Several people said as they walked, they bought food in the cafeteria.

Yuan Shuai said in a low voice while paying, "The food here is really expensive, and one meal is almost enough for me to eat for a month."

This immediately resonated.Everyone was eating while discussing prices in the United States.American industrial products are still very cheap, but everything related to service is very expensive.

Zhao Mengjia talked for a while, took out a small square box from her pocket and handed it to Hao Yunli.

"He asked us to bring you a gift!"

"What is it?"

————————

The small red wooden box is not much thicker than a pen. There is a small cover on it. Open the top cover. Inside is a blue LED connected to the No. 5 battery compartment with a small switch.

Hao Yunli gently pushed forward with her thumb, and a clear blue light lit up.

She looked at the small lamp bead in front of her madly, her eyes reluctant to move away.This is a pure light without a trace of impurities.

"It's so beautiful, right!"

Zhao Mengjia's eyes also focused on the LED.

"When we first saw it, we were just like you. It's like in a dream, with such a beautiful color. It wasn't until we did it ourselves a few times that we slowly got used to it."

————————

Hao Yunli finally looked away from the LED and continued to observe the small box carefully.

Two lines of words are engraved on the bottom plate:

"Maybe it's not bright, maybe it's not strong, but here are the world's first blue LEDs. Producer:"

At the back is the handwritten signature, which can be seen as a happy character.There is a number in the lower right corner, 001.

Looking at the signature and the number 001, a smile filled the girl's face without knowing it.

Yuan Shuai and Zhao Mengjia looked at each other, "If you like it, I will give you mine." Then he handed over another small box.

Hao Yunli glanced at Yuan Shuai in confusion, but still took the box.The two boxes are basically the same, but the signature and number on the back are different:

The signature is "Yuan Shuai" and the serial number is "0001".

Hao Yunli looked at it over and over again and put the two boxes together.

"After number 001, shouldn't it be 002? How did it become 0001?"

Zhao Mengjia took the conversation, "I knew you would ask this, it was his idea."

It turned out that the team made nearly 100 LED samples during the three-day experiment.In the end, more than 50 can be lit.Cheng Yongxing did not throw away these samples, but found an old carpenter and punched a bunch of small boxes.

Put an LED in each small box.Everyone takes turns to sign these small boxes as gifts.Gift to someone who is close or is a teacher or classmate.

The number is even more ingenious.Each serial number can have up to nine digits.That is, from 01 to 09, the new sequence after 09 is 001 to 009, and so on.

Hao Yunli was so confused by the two boxes in front of her that she could only comment: "This is really his style!"

This won unanimous approval, "This is really his style."

That man's poisonous chicken soup is unique, and it can be regarded as an iconic product in his jokes.

————————

"Then what is my real number?"

"I can’t remember. At the time dozens of bright ones were picked out and they were all mixed up. I don’t even remember who did it. Just look at the needs. Like this time we are going abroad, we need to give more gifts. A few people in the country will take fewer.

Not to mention, this little gift is very popular here. When the other person looks at this gift, they know what we have done. It is more convincing than anything."

Yuan Shuai and Zhao Mengjia were also deeply moved by the courtesy they received this time.

"I brought six samples this time. Everyone was very surprised when they received it. We didn't need to speak up. If we increase the size, we will keep us. I hope we can study here.

My original idea was to give these LEDs to others, because the gifts were made by ourselves, so we just need to make another batch.But seeing so many people attach great importance to this gift, the two of us still kept one as our own memory."

"Yeah, it is indeed memorable. I am a little envious of you. Maybe we will never have such an opportunity in our lifetime to witness the birth of a miracle."

Put down the small LED box.Several people talked about the project the LED team is currently doing.

When I heard that this LED patent negotiation, the contract amount has reached more than 200,000 US dollars.Hao Yunli was taken aback.

"No wonder he doesn't go abroad!"

Yuan Shuai pouted, "He was angry, thinking that there was too little money, and he was ready to show his power. He did a batch of experiments, and he hadn't published it when I left."

"Does 200,000 dollars cost less?" Hao Yunli was taken aback again. If Hao Yunli graduated, it would take almost 7 years to earn 200,000 dollars.

"He hopes to sell for at least one million dollars. We have been doing experiments before we left, and now it is estimated that it should be almost done."

————————

Hao Yunli no longer knew how to answer the call.Had to change the topic

"How are you all this time? Didn't Berkeley give you an offer?"

"Yes, but not as good as yours. Because of participating in the LED group, they provided us with a scholarship for undergraduate and master's degree consecutive studies, and we can transfer over at any time."

"Great, so that we can see each other often. You don't know, I'm so lonely here, I can't find anyone in chat. When you arrive in the United States, at least we can call every day, and we often meet during the holidays!

I have a salary now, and I will often fly over to see you!"

Hao Yunli almost jumped up when she patted the table.

Yuan Shuai hesitated.

"We are still thinking about it, but it may not come in a short time. There is also the possibility of not coming."

"Why? What happened to you all?"

Hao Yunli was going crazy.
