Shenyang.
After Khrushchev attended the National Day celebrations, he also arranged to visit several cities such as Shenyang, Harbin, and Dalian. It took about 10 days in total, and he returned to the Soviet Union in mid-October.
This is the correct way for a state visit. Looking at China's development achievements in the past 10 years, you can also look at the imprints left by the key Soviet aid projects that can be seen everywhere. Don't both sides enjoy themselves.
If it was the same as the original history, then Khrushchev would suffer.I stayed in Beijing and debated the scriptures with the Chairman for a week. The debate was nothing more than a trivial matter. The Chairman invited Khrushchev to swim and talk while swimming.The chairman floated in the water for two hours and still felt that he still couldn't get enough of it. The history of the Communist Movement was only halfway through, and Khrushchev could only lie on the swimming ring to breathe.
The group traveled from Beijing to Shenyang by special train, accompanied by Li Fuchun, Tan Zhenlin, Tang Hua, Liu Nai, and Qian Zhiguang.
The first thing I didn't expect when I went to Shenyang this time was the traffic jam.
This is an era when there were basically no private cars, Shenyang, traffic jams.
After the special train arrived at the station, the convoy got stuck twice on the way from the train station to the hotel for three to four kilometers.I saw buses, trolleybuses, large commuter buses bought by the big factories themselves, large trucks, medium trucks, and jeeps that were busy transporting goods and traffic, clogging the main road, and the torrent of bicycles in Wuyang Wuyang...
Who let the special train arrive at Shenyang and get off the train to catch up with the evening rush hour?At this time, there was no programmed system to clear the way for foreign guests and leaders.
"No wonder Shenyang reported last month that it applied for the construction of a subway." Li Fuchun said.
Tang Hua: "Shenyang built a subway... a little early."
Li Fuchun: "The Heavy Machinery Bureau of the Ministry of Heavy Industry can make shield machines. If we find a way to solve the EMUs for subways, we can handle most of the subways by ourselves."
Tang Hua: "The Heavy Machinery Bureau can make 2.6-meter and 4-meter shield machines, which are mainly used for mine and tunnel construction. For subway construction, 6-meter shield machines should be used. Of course, 4-meter shield machines can be made, and 6-meter shield machines can be used. Mi can be done sooner or later, but it will take time. Mainly, I think that although the cities of Beijing, Shenyang, Changchun, Shanghai, Tianjin, and Wuhan are developing very fast, they are not yet to the point where they cannot do without the construction of subways.”
Tan Zhenlin: "Britain had a subway in 186. At that time, China was still in the Manchu Qing Dynasty, and the Old Summer Palace had just been burned by the British and French allied forces. It will be almost 100 years since the world's first subway was opened to traffic. Our relatively fast-growing central city was the first to build it. The subway is not particularly exaggerated."
Tang Hua: "It is possible to develop a little ahead, but the difficulty is that the investment is relatively large."
Liu Nai: "Actually, this subway also has the function of civil air defense."
The first subway in the Soviet Union was Line 1935 (Red Line) in Moscow in 1, and then Line 2 (Green Line) and Line 3 (Blue Line) were repaired immediately. During the Battle of Moscow, all three subways were opened. At this time, the Soviet Union discovered The second benefit of using the subway: as long as the subway is out of service, it is an excellent civilian air defense shelter.
Not only civilians, but the Soviet authorities also got into the subway when the defense of Moscow was at its most dangerous. The office of the Council of Ministers was relocated to the Mayakovsky Station on the No. 2 subway line.Stalin also often stayed at Mayakovsky Station, and he gave public speeches over the radio many times here.
During the nuclear war, in fact, it is difficult for the atomic bomb to destroy the subway tunnel. The property of the subway extending in all directions can also allow civilians to run farther and evacuate to a safe area before going to the ground, without having to go to the ground to eat radiation.
So it seems that repairing the subway is not impossible...

Shenyang No.[-] Machine Tool Factory.
When Khrushchev came to Shenyang, the first project he visited was Shen Yiji.This is currently China's cutting-edge industrial mother machine production plant, and it is also one of the key projects aided by the Soviet Union. Moreover, Shen Yiji has a follow-up Sino-Soviet cooperation plan, so Khrushchev must come here to check in.
Just like when the chairman came to Shenyang to visit Shenyi machine five years ago, he walked around the production, testing and assembly workshops of various machine tools, and the factory manager brought a group of people to the CNC machine tool display workshop.
"Numerical control machine tool is an automatic machine tool equipped with a program control system. It is actually a machine tool with a computer. The numerical control computer sends out various control signals through calculation and processing to control the movement of the machine tool. According to the shape and size required by the drawing, Automatically process the parts..."
The factory manager introduced the CNC milling machine in front of Khrushchev. Khrushchev did not have a background in science and engineering. In fact, he had no higher education.When the factory manager introduced the CNC machine tool, Khrushchev listened to the introduction with a polite smile.
"Now we will show you the working process of this CNC machine tool," Tang Hua came up, showing a three-dimensional drawing, and then held up a brass rod and said, "In 15 minutes, this CNC machine tool will process it into What it looks like in the drawings, and all the operations are done by the computer, you only need to press the 'start' button."
Hearing what Tang Hua said, Khrushchev was very surprised.Tang Hua asked the worker to put the brass rod into the processing table, fixed and calibrated it, and then led Khrushchev to the computer console, reminding him to press this button.
As soon as Khrushchev pressed the button, the CNC machine tool started to move, the flexible cutter head kept flying up and down in the glass cover, and the six water nozzles continuously sprayed water on the copper rod to cool the workpiece.
Several people who accompanied Khrushchev had seen the work of CNC machine tools, but Khrushchev and Suslov had never seen it.The two kept yelling wow and oh, and regardless of the safety distance of 4 meters in the operating specifications, they just walked two steps forward to see how the CNC milling machine works.
The milling machine was originally used to process steel products. It is basically not difficult to process brass, and it can be processed very quickly.
After 15 minutes, a realistic, almost identical brass corn cob sculpture was completed.The worker opened the glass cover of the CNC milling machine, took out the hot sculpture with his gloved right hand, sprayed it with cold water to cool it down, dried it and handed it over.
Khrushchev held up the copper corn, turned left and right and looked at it carefully, smiling from ear to ear.Reporters from China and the Soviet Union hurriedly captured this historic scene.
"Comrade General Secretary," Tang Hua said, "The machine tool technology cooperation project discussed between China and the Soviet Union has already started. Shen Yiji and the Leningrad Electromechanical Instrument Factory will cooperate together. Shenyang will provide industrial computer solutions, and Leningrad will develop the next generation High-precision parts, and jointly create a cutting-edge industrial mother machine for the socialist camp."
Khrushchev laughed, "This little console can replace two skilled workers. If all factories are like this, then communism has arrived."

Shenyang Aircraft Factory.
Khrushchev's second visit to Shenyang.
After the implementation of the 150 key projects in the First Five-Year Plan, China continued to import 19 key projects from the Soviet Union during the Second Five-Year Plan. These projects were considered commercial imports, and China paid according to the price, but it is also a Sino-Soviet alliance to get these things. Still a solid proof.
Shen Fei's key project during the first five-year period was the introduction of the MiG-17 production line. Now the J-5 has been put into production for more than three years.During the Second Five-Year Plan period, Shenfei introduced the MiG-21 production line.
1958年完成了新厂区基建，1959年2月安装苏制设备，预计1960年1月可以用苏联提供的零部件组装制造米格-21，随后逐渐提高国产化率。
"Three years ago, the J-5 was just built, and now it is about to enter the era of supersonic fighter jets, and it has jumped to twice the speed of sound in one step. How do you feel?"
Khrushchev visited the MiG-21 production line workshop, and Tang Hua went to Shenyang Aircraft Design Institute.
Huang Zhiqian: "After receiving the drawings and technical documents, most of the people in the design institute, including me, refreshed the basic knowledge system of aviation again."
Tang Hua: "I have a question. After reading the MiG-55 materials in 56 and 17, have you ever thought about: 'If I am the original creator of this set of drawings, how did I imagine the MiG-17? What should the next generation of aircraft look like? Where should we start to change to improve the key technical and tactical performance of fighter jets?'”
The backbone of several design institutes present hummed and chirped.
One or two wanted to speak, but felt unable to form words.
After a moment of silence, Huang Zhiqian said first:
"After getting familiar with the design of the MiG-17, I thought about some plans for new fighter jets, with supersonic speed as the main design purpose. There is a design plan, and I feel very good about it. However, in 57 we saw the MiG The brief information on -19, and I went to the Soviet Union to see the actual aircraft, so I felt that there was no need to mention my plan.”
"Is it equipped with an engine with greater thrust, and the main wing has a greater sweep angle to adapt to the aerodynamic shape of supersonic flight?" Huang Zhiqian said that he shrank after seeing the MiG-19, and Tang Hua guessed what the design might be.
Huang Zhiqian nodded.
"That's okay, it means that you have put yourself into the perspective of a designer, not an imitator or a reverse engineer."
Huang Zhiqian: "But I stopped when I thought about increasing the sweep angle. Hey, Xiao Song actually came up with a plan, put it in a wind tunnel and blow it through, and it can basically fly, but then I didn't talk about it."
Tang Hua looked, it was Song Wencong.
"I...the fighter I designed is not a delta wing either, and it can't be synchronized with the MiG-21." Song Wencong was a little nervous when he spoke.
Tang Hua: "Probably describe what it's like."
"Swept wings are also used, and the sweep angle is not particularly increased. The wings are widened and thickened, and the strength is increased so that they can cross the sound barrier and achieve supersonic speed. However, the wind resistance of the wings designed in this way is relatively large. I used two more The side intake is bigger, and the current engine cannot support this fighter design."
Hey, does this mean the F-105?
"According to your description, this is a bit like the F-105 "Thunder" in the United States." Tang Hua said.
