Institute of High Energy Physics, Chinese Academy of Sciences, is a direct unit of the highest academic research institution in China. Its predecessor was the Institute of Modern Physics, the Chinese Academy of Sciences, which was founded in 1950. It was later renamed the Institute of Physics and the Institute of Atomic Energy. ⊙Now there are 1,500 employees, including about 1,200 professional and technical personnel, including 8 academicians of the Chinese Academy of Sciences and 5 academicians of the Chinese Academy of Engineering. It also has various national-level centers and 15 laboratories.

As the leading expert in microelectronics, computer and theoretical physics in China and an academician of the Chinese Academy of Sciences, Lin Dong is now working in the Institute of High Energy Physics. He is also the deputy director of the Institute of High Energy. He is mainly responsible for the three units of the Experimental Physics Research Center, the Theoretical Physics Room and the Computing Center. His daily work is extremely busy.

After returning from Shimen, Lin Dong continued to devote himself to the intense and busy work. Although he is older now and his physical condition is not as good as before, he can no longer do everything like he did in the past few years. However, the habit he has developed for many years, Lin Dong will still arrive at the office at around 9 a.m. every day, and then review the documents for about two hours. Next, he will go to the three centers to listen to the actual report of the center's person in charge to understand the research progress of each project.

Today, Lin Dong still went out on time as usual and came to the office in the driver's car. Secretary Xiao Tang had already made tea for Lin Dong. After Lin Dong sat down, he reported today's work arrangements in concise words.

After listening, Lin Dong signaled Xiao Tang to take the documents to be issued today first. After a while, Xiao Tang took a few documents and Lin Dong asked him to put them on the table. Without any objection, he looked up and saw that there was a stack of things in Xiao Tang's hand, and immediately asked what these were.

"These are letters sent from all over the country, and they are ready to be processed by the Comprehensive Office."

"Letter?" Lin Dongyang raised his eyebrows and smiled and reached out to Xiao Tang, "Show me, are you sending me a letter?"

"Old Lin, but these letters..." Xiao Tang did not hand them over, but hesitated for a moment.

"I know, I know." Lin Dong nodded and smiled, "Are you just worried about my body and I was not energetic, so you specially set up some comprehensive work. In my opinion, this is a waste of manpower and material resources. I have to deal with it myself if I have to put it in the past. Anyway, there is nothing wrong today, so let me, the old man, take a look at it myself."

"But Mr. Lin, Aunt Jiang has confessed..." When Lin Dong wanted to handle the letters by himself, Xiao Tang blamed himself for his negligence just now, why did he bring them over? Although these letters are not many, Xiao Tang, who has followed Lin Dong for many years, is very clear about the character of the old man. When he handled the letters by himself, he not only read each letter very carefully, but also wrote back to some senders, either praise or encouragement. Even if the content of some letters is of no value, Lin Dong would reply to the elder and teacher to encourage the other party.

But after Lin Dong's heart had a bypass surgery a few years ago, his physical condition was much worse than before. In order to ensure Lin Dong's health, the institute specially equipped him with a comprehensive department. The main job of this comprehensive department is to assist Lin Dong in handling these letters. Most of these letters were written to Lin Dong by grassroots researchers or physics enthusiasts from all over the world. Some asked him questions, some proposed some ideas, some were some ideas, and some were almost fantastic in the comprehensive department, and there was no value at all. Therefore, the comprehensive department would uniformly disseminate and read and organize these letters in advance, unless it was considered necessary to hand over the letters to Lin Dong himself, basically all of them were handled by the comprehensive department.

"If you don't say it, I won't say it, how could you Aunt Jiang know? Besides, I don't think there are a few letters. OK, okay, take them all." Lin Dong smiled at Xiao Tang like an old child. Xiao Tang hesitated for a moment, and finally put the letters on Lin Dong's table.

When wearing reading glasses, Lin Dong first reviews the files in his hand. When reading the files, no matter how much the content is, he will look at them carefully line by line. In some more important documents, Lin Dong will read them repeatedly, and then write down his personal opinions and suggestions in the blank space of the files.

Although there were not many documents, Lin Dong also spent an hour. After all the instructions were completed, he placed the last document neatly on one side, took off his glasses and rubbed his slightly sour eyes, then picked up the teacup and drank a sip of tea. After putting down the teacup, Lin Dong saw that there was still more time, so he reached out to pick up the letters left by Xiao Tang from the other side.

Of course, reading letters will not be as difficult as reading documents. In fact, Lin Dong asked Xiao Tang to leave these letters today because there were indeed no important arrangements today, and secondly, he also wanted to adjust them in this way, or miss his previous working style.

After reading the first two letters, Lin Dong couldn't help but shake his head slightly. These two letters were written to Lin Dong by grassroots technicians who claimed to have research on physics. The contents in the letters were basically the same. They all put forward some so-called "discovery" or "invention" and wanted Lin Dong to give some opinions.

However, Lin Dong could see at a glance that these so-called things are simply sensationalism. The motivations of the writers are impure and the content is empty. In recent years, there have been more and more such people. With the materialization of society and the hearts of people are irresistible, fewer and fewer people can calm down and do research. Many people want to take shortcuts or use this method to raise the banner. Seeing such letters makes Lin Dong really bad. He frowned and sighed that why young people today are unwilling to do research as solidly as they used to, and are keen on such evil ways?

Throwing these two items aside, Lin Dongfei would not reply to this kind of letter, and even the only result of the letter when he arrived at the comprehensive office was thrown into the garbage dump. The next letter made Lin Dong feel better. The letter was written by a young researcher from the Northeast Research Institute. The content was to ask Lin Dong for questions about microelectronics. This researcher has a good foundation and has a thorough theoretical analysis of the questions he asked for. Although the personal opinions raised are some minor problems, the overall flaws do not cover up the merits, and there are some highlights and personal ideas. Seeing this content, Lin Dong nodded with praise, picked up a pen and circled them in several places in the article, and then put them aside alone, preparing to wait until the remaining letters are finished before processing them separately.

After reading a meaningless letter, Lin Dong felt a little tired. However, there was still the last letter on the table. Lin Dong picked up the teacup and drank water while taking out the letter with his other hand.

"Huh!"

After taking a look, Lin Dong was stunned at first, then suddenly widened his eyes. Because there was no text in the letter, it was a hand-drawn integrated circuit drawing. As an expert in microelectronics, Lin Dong almost recognized that this integrated circuit drawing was just a partial diagram, and it was a partial diagram of a primary general-purpose integrated circuit that had long been eliminated. However, when Lin Dong saw it at first, he was shocked, and even forgot to put the teacup in his right hand down.

"This... how is this possible... how is this possible!" Lin Dong's face changed drastically, his hands trembled uncontrollably. When he loosened his right hand, the tea cup fell on the table. With a bang, the cup of tea splashed everywhere, but Lin Dong didn't care about these things at all, and still stared at the drawing with an incredible gaze.

"Old Lin!"

Hearing the sound in the room, Xiao Tang rushed in quickly outside. At first he thought something had happened to Lin Dong, but when he saw Lin Dong being so good, he felt relieved, but at first he saw the teacup that was knocked over on the table, he quickly yelled, found a rag and hurriedly helped Lin Dong clean up.

But after a few wiping, Xiao Tang found something wrong with Lin Dong. He saw Lin Dong still sitting blankly, his expression full of astonishment, confusion and incredible. He was holding a hand-drawn drawing that looked ordinary, and his excited body was trembling slightly.

"Old Lin...Old Lin..."

After a few whispers, Lin Dong came to his senses, but he suddenly started rummaging on the table wet with tea. Xiao Tang didn't know what Lin Dong was looking for. Just when he was about to ask, Lin Dong finally found an empty envelope.

"How could this happen?" The envelope was soaked with tea, almost all of it was wet, and even the words on it were blurred. Seeing this, Lin Dong suddenly became anxious and grabbed the rag from Xiao Tang's hand and wiped the envelope in a hurry, trying to save the words on it.

"Old Lin, don't wipe it, these words are all confused."

"What do you know!" Lin Dong, who has always been a gentle elder, shouted at Xiao Tang in an unprecedentedly stern tone, with anxiety and urgency in his expression, as if this envelope was not just an ordinary envelope, but something very important to him.

Xiao Tang felt extremely aggrieved. He didn't know why Lin Dong was suddenly so excited, because what he said just now was right. The envelope soaked in tea had no value in salvation. All the words written in the pen on it turned into unrecognizable ink traces.

But no matter what, as Lin Dong's secretary, Xiao Tang, who has followed Lin Dong for many years, knows the old man's personality very well. If it weren't for something particularly important, Lin Dong would definitely not be like this. Although Xiao Tang does not understand what the envelope has for Lin Dong, nor does he know what the hand-painted ordinary drawings represent, but since Lin Dong pays so much attention to them, there must be a reason he pays attention to them.

After staring at the drawing in Lin Dong's hand, Xiao Tang suddenly remembered that he seemed to have seen something similar before. He quickly told Lin Dong about this. When Lin Dong heard this, he hurriedly asked Xiao Tang where he saw it. Xiao Tang recalled carefully and confirmed that he must have seen it at the comprehensive location. It seemed that there were several letters before that there were such drawings in it, but no one cared about it.

"Look! Go and find it! Hurry!" Lin Dong urged anxiously, looking at his appearance, wishing he could go to the comprehensive office to search by himself. Xiao Tang quickly agreed and advised Lin Dong not to be anxious. He would go to the comprehensive office to search immediately, because according to the work procedures of the comprehensive office, as long as those things were not treated as waste, they would definitely be found.

"Okay, okay, okay!" Lin Dong said three good words in a row, and his excitement finally calmed down a little. At this time, Xiao Tang did not dare to delay and hurried to the door. When he just walked to the door, Lin Dong called him again. Xiao Tang turned around and thought Lin Dong had something to explain, but who expected Lin Dong apologized for his attitude just now. Looking at Lin Dong, Xiao Tang felt warm and he had no grievances in an instant. He focused on Lin Dong and rushed to the comprehensive office quickly.
