This kind of thing happens all the time. In addition to chips, macro circuits are actually very scary to look at.

Because most components are standard and have model numbers on them, you can tell what they are at a glance.

In order to prevent us from imitating them, foreigners even guard against dragons like thieves, removing all the markings on the electronic components of switches and satellite signal receivers sold to the mainland!

Under the planned economy, in order to improve the level of each factory, the leaders even personally organized friends and businessmen to visit. Of course, the inventors would have great opinions.

But Li Sanbiao was not afraid to see it. He returned to the factory and engraved a chip in front of the supervisor.

Then install it on the switch.

Li Sanbiao dialed and successfully dialed the phone number of another house.

The supervisor frowned and said: "This only means that the switch is available. How do you know it is 10,000 switches?"

Li Sanbiao said: "You can first find a C5 bureau to test it. If it succeeds, you can continue the experiment in C4 bureau, and then expand to C3, C2, until C1 bureau."

The supervisor nodded slightly and said: "Okay, we will take your switch away first. The experiment will take about a month, so you can wait patiently here."

Li Sanbiao said: "I have an unkind request. I hope to conduct this C5 Bureau experiment in Gubeikou. I wonder if you will agree?"

The supervisor was stunned for a moment: "Why? That place is very remote!"

Li Sanbiao said: "This place is my hometown and the battlefield of the Great Wall Anti-Japanese War. Because of the steep terrain and inconvenient communication, I hope you can help them open a line. During the Great Wall Anti-Japanese War, because of the heroes who supported the cannons at Mizoguchi

, many people were killed in our village. This machine is free of charge, so we treat it as a gift to our hometown."

The supervisor said: "Okay, then according to your opinion, we will start pulling the phone lines to your village tomorrow."

Li Sanbiao has not been back to his hometown a few times since he was born, because the mountain roads can no longer be described as rugged.

Because Gubeikou Village was originally a military stronghold in the mountains and mountains used to support the defenders of the Great Wall in the Ming Dynasty.

There is an ancient saying: "The capital controls the frontier in the north, and Shuntian belongs to Songting, Gubeikou, and Juyong Pass as the main points, and Gubei is Youchong." Outside the passes is Chengde.

Emperors Kangxi and Qianlong praised it many times, praising it as "the earth strangles the throat and goes back to the desert, and the sky locks the key and pillows the majestic pass", and is described as the key to the capital.

Gubeikou Railway Station is the only way to get here. After exiting the station, you will reach Gubeikou Village. At the entrance of the village is the tomb of the martyrs during the Anti-Japanese War.

Li Sanbiao took a dozen engineers and workers to the entrance of the village.

The village party secretary heard yesterday that a group of leaders were coming, and he had already led the village cadres to greet them at the entrance of the village.

The village was immediately filled with the sound of dogs barking.

The village party secretary is also surnamed Li, and he is Li Sanbiao’s distant cousin.

The composition of this village is complex, not just one family has one surname.

Because Li Sanbiao's father went to the city and became a cadre, the villagers recommended his uncle, who was closest to him by blood, to be the cadre of the brigade. Of course, they wanted to take advantage of the opportunity to get some glory.

Unexpectedly, Li Sanbiao’s father is a technical cadre, and he is in the electronics field.

To be honest, no matter whether it is civil construction, steel, or textiles, there are basically channels to help your hometown.

Only the electronics industry does not overlap with the needs of my hometown. Moreover, my father went to Chang'an Research Institute again, and there is no news about his hometown.

Therefore, Li Sanbiao's second uncle was very depressed, and the whole village was poking their backs and pointing fingers.

The second uncle asked Uncle Dong for help once, and Uncle Dong had many connections.

Only after every household in the village has electricity and electric lights installed can the second uncle's position as village chief be firmly established.

This place is very remote, and the telephone at the entrance of the village is still old-fashioned. He can hear it very clearly. In fact, he has no idea what is going on. He thought it was the county sending people to check the autumn harvest preparations, but he did not expect to see Li Sanbiao.

"Biaozi! You don't live in the city, why do you want to go back to your hometown? Are you here with these leaders?"

Li Sanbiao laughed and said: "You don't know yet, the leaders of these telephone offices are here to lay telephone lines for our village!"

The village party secretary thought he heard wrongly: "Isn't there a telephone line at the entrance of the village? Why didn't you tell the leader earlier?"

Li Sanbiao smiled and said: "Second uncle, they are planning to install telephones in every house for us!"

The village party secretary didn't believe it at all: "Biaozi, you are Zhang Biaozizui. One day, you will really realize the four modernizations, that is, you can have upstairs and downstairs in the city, electric lights and telephones! Our village is very satisfied with electric lights.

It’s impossible to talk to everyone on the phone!”

Li Sanbiao said in his heart that there was no cure. People today cannot imagine the world 40 years from now!

But the captain who came to lay out the lines at the telephone station showed his work ID.

"What Comrade Li Sanbiao said is true. He has secured an experimental opportunity for your village to conduct a village-wide end-to-end Internet call experiment. We also hope that every household in the village will cooperate with us!"

The villagers were so excited that they wanted to inspect the laying of telephone lines for themselves. They were so happy.

"It's true! Biaozi really installed a phone for us!"

"Tsk tsk, you are worthy of being a descendant of Mr. Li from the private school. He will not forget his roots when he enters the city!"

"Mr. Li has been through the ages, we must collectively pay tribute this year!"

The village party secretary straightened his back, smoked a dry cigarette pot, and raised Li Sanbiao to accept the compliment, as if he had brought the telephone exchange.

He now has even more face. After all, Li Sanbiao is his cousin, so he can say that he said it with great effort, which can obviously further enhance his prestige.

Li Sanbiao didn't bother to care. Village cadres are like this. They often have to rely on relatives outside, otherwise they can't manage at all.

The construction team of the telephone office followed the villagers to inspect each house, found the electric wires of the lights, and smoothed them.

Although the telephone lines do not require municipal power supply, they also want to see how the power grid is routed, which can save a lot of effort in designing the lines.

In order to speed up the construction, the original wooden telegraph pole was used and a wooden strip was nailed to the side of the pole as a support point for the telephone trunk line.

After working for a day, the captain said to Li Sanbiao: "Don't worry, the village telephone will be laid in half a month."

The villagers were very enthusiastic. They killed several old hens and a pig, and made a table of pig-killing dishes to entertain Li Sanbiao and the construction team.

The village party secretary apologized: "Our village is poor, so we can only scrape together this table of food this year. The food may not be as good tomorrow, so leaders, please bear with me."

Li Sanbiao also felt sad. This village is at the foot of a mountain. There is no three-foot flat land, and the mountain is full of rocks. It is impossible to even build terraces in this kind of mountain.

Li Sanbiao said: "Let's do this. Let's think about it tomorrow to see if there is any way to get rich!"

Li Sanbiao found a big river not far away and a village on both sides of the river, but he was not familiar with it, so he asked: "The scenery of that river is not bad, what kind of river is it?"
