"Secretary Zhang, this is Li Jian, a senior high school student at Chunjiang No. 1 Middle School, in order to meet you today, he didn't go to the city's joint entrance examination."

Luo Rongguang grabbed Zhang Zhihua's hand, did not part for a long time, and introduced Li Jian to Zhang Zhihua in a familiar tone, Li Jian took this opportunity to look at Zhang Zhihua, forty-five or sixteen years old, he looked like a scholar, and at the same time Zhang Zhihua was also looking at Li Jian.

Shocking, really shocking, Zhang Zhihua had heard Luo Rongguang introduce Li Jian's basic situation before, but when he saw Li Jian himself, it was still difficult to turn the little boy in front of him, who looked like he was only sixteen years old, into a paper mill with a profit of nearly 100,000 yuan in more than a month, and even designed a cordless phone that was not even available in foreign countries, which was too young.

"Secretary Zhang is good."

Li Jian hurriedly said hello, took a step forward, held Zhang Zhihua's hand with both hands and shook it, Zhang Zhihua patted Li Jian's shoulder with a smile and said a word,

"The afterlife is terrifying!"

Zhang Zhihua is not alone, there is still a young man who looks like a secretary sitting in his office, at first Li Jian really thought he was a secretary, but when he saw Zhang Zhihua shake hands and sit back, the young man didn't move, and Luo Rongguang didn't say hello to this person, so his eyes fell on his face.

Sure enough, the young man's face was tired, and there were black marks left by staying up late all year round in the corners of his eyes, and he suddenly understood something in his heart.

After Luo Rongguang let him aside and sat down, the main drama began,

"Xiao Li, I heard that you are also involved in program-controlled switches, this is our teacher Qiu of BUPT, I want to see how much you have mastered, if you can, he can recruit you to go to college in BUPT, anyway, you are also a senior high school student, as for the tuition or something, the school will give you full exemption, I will come forward, and the city can also give you a part of the subsidy."

"Special moves? Walks? Forget it, I'll take the test myself, this place is still reserved for those who need it more! Li Jian replied casually, seemingly not interested in this suggestion.

At this moment, Zhang Zhihua suddenly realized that the middle school student in front of him was not an ordinary middle school student, but a private boss who turned stones into gold, a telephone set made thousands of yuan, and was an extremely tempting bait for ordinary students, like a floating cloud to him.

"Hello to the teacher of Beijing Post and Telecommunications, you and the Ministry of Posts and Telecommunications should be working on 2,000 doors, and they are about to overcome it, right?" Li Jian immediately found a sense of intimacy with the so-called researchers, and he was much more comfortable than facing an official like Zhang Zhihua, especially since the other party was not much older than him, and he should be one of the few public students on public assignment at that time.

He asked so directly that he was not afraid of attracting the attention of others, everyone knows that the Ministry of Posts and Telecommunications wants to build 2,000 doors, and since Li Jian understands the switchboard, it is normal for him to be more concerned about this.

"Now we encounter some problems, there is always a code change in the process of digital information conversion, and the transmission error rate between the trunk and the user line is too high, alas, it is still because the integration of the circuit is not enough, and Batumi does not allow us to import those necessary chips, so we are very limited!"

When it came to technical problems, the young man was finally willing to open his mouth, and he did not despise Li Jian at all because of his young age.

"I know what you're talking about, our chip integration rate is too low, so you split the work that should be undertaken by a chip, divide it into three to five pieces, and cooperate with each other to complete the data transmission work, but it is easy to produce code change ...... in mutual transmission."

Li Jian understood the domestic situation at that time, the defects in integrated circuits were very large, and these scientific and technological workers could only save the country by curves, and the task completed by one chip was split into several chips, and these scientific and technological workers could be said to have hollowed out their minds for the sake of scientific and technological progress.

As soon as Li Jian opened his mouth, the two young people couldn't hold their mouths, completely ignoring that there was also a secretary of the municipal party committee at the prefectural and departmental level and a deputy county magistrate with the position of deputy department at the regimental level, and they chatted for two hours.

The 2,000-door program-controlled digital switch was a technical problem in China at that time, but it was already a rotten street technology in foreign countries, Li Jian knew that there was a 1,000-door switch technology developed by later generations, all intellectual property rights were state-owned, and even the chip design was produced in the country, so he took out this set of ideas.

Li Jian thought about making a switch, but if he was allowed to do it himself, it would require a lot of money, scientific research personnel and various materials, and with the strength of his current telephone factory, he would still need to work for three or five years to save enough funds to start.

And can the current situation of the domestic communications industry wait? No! Li Jian didn't want to be reborn again, and when he could change it, he also saw the seven countries and eight systems, and also saw that the rooster's map was full of the communication territory of the entire country ruled by the eight colors representing the great powers.

If you can't do it yourself, then let someone else do it, as long as you are a countryman, and you must not allow the great powers to grab huge profits from their homes again and exploit our people.

And this development is to promote the overall layout of the country, the rise of the huge golden China in the last life, so that the domestic communication manufacturing industry and the chip manufacturing industry as a whole have taken a step up, especially into the microprocessor that can already be manufactured by itself, the meaning of which can be different from the cordless phone designed by Li Jian.

"Xiao Li, your thinking is too broad, if it weren't for the fact that you were still in high school, I would have thought that you were an old expert of our institute, and if you can selflessly contribute these studies today, the country will definitely not forget you."

After chatting with Li Jian for more than two hours, the young expert who didn't know his name and didn't even introduce his name suddenly became enlightened by many problems that he couldn't think of, or that could not be solved due to the limitations of science and technology at that time, and he was suddenly so excited that he held Li Jian's hand and was unwilling to let go.

"This is all to contribute to the country, in fact, what I want to say is that after you get the 2,000 doors of technology out, it is best to go to the international market to apply for a patent, so that foreigners know that we can also do 2,000 doors ourselves, and the military seems to be doing 10,000 doors, you can coordinate with them, presumably with you new forces to join, the day of the localization of 10,000 doors should not be far away, that Batumi, the technology we have mastered is not blocked, so we should be able to buy some chips in."

Li Jian's words, listening to Zhang Zhihua's ears, seemed to see a gray-haired old researcher whispering to his juniors, but the reality was that an eighteen-year-old high school student was instructing a twenty-six-year-old researcher at the Ministry of Posts and Telecommunications, and the gap between the two shocked him too much.

This Li Jian, by no means a thing in the pool, he just wanted to use the escort quota and subsidies to envelop him, it seems that he really underestimated him, a small secretary of the municipal party committee, I'm afraid there is no way to envelop him, presumably after this person goes back this time, he should be met by the leaders of the Ministry of Posts and Telecommunications, and even the leaders of the Ministry of Electronics Industry.
