Except for the two little girls and Tang Wan, the rest were engineers. After a little thought, they understood the meaning of Liang Yuan’s speech and the benefits of this new system.\\First release 13800100yd First release\\

Wang Xin looked at Li Yuanling and said, "Sister Li, I admire you more and more. Xiaoyuan is so talented. I really don't know how Sister Li cultivated it."

Li Yuanling could only shake her head helplessly. After Liang Yuan invented the air conditioner fan, Li Yuanling had discussed it with Liang Jiangping several times in private, but she couldn't figure out how her son was a genius in engineering applications. In the end, she could only attribute it to the hearing and seeing things in the family since she was a child and the letting education of the two.

"Sister Wang Xin, you just wanted to call a freak." Liang Yuan asked with a smile.

"You are, do you still use Wang Xin to say it?" Li Yuanling rubbed Liang Yuan's hair and said.

Liang Yuan has always called Wang Xin, who is less than 30 years old, and Wang Xin and Li Yuanling are also sisters. When Li Yuanling found out, he felt that this generation was inconsistent and corrected Liang Yuan several times, but unfortunately there was no effect. Later, Liang Yuan was called all the younger women in the Science and Technology Park. In the end, Li Yuanling could only let Liang Yuan scream casually.

Several people stayed in the exhibition light group area of ​​the Science and Technology Park for a long time. After leaving the canvas fence, they looked at the revolving lanterns provided by the gas engine laboratory. After seeing the train sand table in the chip laboratory, the two little girls' eyes became obviously "sharp" and they lacked interest in some lighting that attracted attention by their shapes.

Liang Yuan criticized the revolving lanterns fooled by the two little girls, and heard them nodded frequently.[][ [First release] As a result, Li Yuanling was repaired.

After visiting the light show, it was already late at night when I came out of Nanhu Park. Li Yuanling and Tang Wan had not seen each other for a long time and pulled Tang Wan back to the 909 community. The two little girls naturally agreed with this decision.

Several people returned to the Science and Technology Park to carry the items purchased during the day onto the car, but found that Volga's trunk was not enough, so they had to put some of the goods in the back seat. The smaller two loli were naturally unable to squeeze in. They waited at the entrance of the Science and Technology Park for a while but could not see a taxi. Finally, Tang Wan decided that a little girl and Liang Yuan were squeezed in front, and the remaining space of the three people could barely sit down.

Faced with this kind of problem, Ning Wanfei didn't even need to guess the result, so she went straight into Volga's back door.

A refreshing and fragrant breath lingers at the nose. Holding the delicate body in his arms, Liang Yuan felt his heart beating all over. Although he would occasionally rub against Ning Wanjia's ears and faces, Tang Wan was still a little nervous. After all, he always felt guilty when he hugged his daughter in front of his mother-in-law.

Ning Wanjia was no exception. She found a comfortable position to lean in Liang Yuan's arms, with a smile on her face, and even her big eyes bent.

"Yuanling, I really don't know how you educated Xiaoyuan. I was really convinced by Xiaoyuan when I saw the chip experiment." Tang Wan said with some emotion.

"I went home during the Chinese New Year this year, and I told the old man about Xiaoyuan in detail, making the old man more interested and asked me to convey it to Xiaoyuan. In the future, I must go to Muxidi to go to Beijing in the future," said Tang Wan.

Liang Yuan grabbed his hair and said, "Aunt Ning, Mr. Tang is also a national leader, I'm a little nervous. Starting the show."

"What are you nervous? You're not going to the front line. Aunt Ning doesn't believe you will be nervous." Tang Wan reached out and rubbed Liang Yuan's hair.

"Grandpa is a very friendly person." Ning Wanjia whispered in Liang Yuan's ear.

Liang Yuan listened to Tang Wan's joke. However, he felt a little mixed in his heart. Now Tang Wan has completely agreed with him. The childhood sweetheart relationship between him and Ning Wanjia is planned to bring himself into that high-ranking circle.

"I have heard of Xiaoyuan. If Yuanling hadn't been busy with her career, she would strongly oppose it. My brothers were willing to send the child to Shengjing and ask Yuanling to help discipline him well." Tang Wan said with a smile.

"Xiaowan, since childhood, Xiaoyuan has also grown up under your nose. How can you hide the education from you?" Li Yuanling said with a wry smile.

"Yes, I told them too. Xiaoyuan is definitely a genius among his peers. He is a special case. Education is only part of the factor."

"Xiaoyuan just has more ideas." Ning Wanfei muttered in a low voice.

"Feifei, the teacher at school said that we were both smart, but we never beat Xiaoyuan by bet." Ning Wanjia agreed with Tang Wan's point of view very much.

"Jiajia, you're beyond help." Ning Wanfei said with a pout.

Li Yuanling listened to the two little girls quarrel and said with a smile: "No matter what kind of genius he is, he will not listen to Jiajia in the future."

"That's right, I, a girl, said nothing." Tang Wan smiled and pinched Ning Wanjia's cheek.

Listening to Tang Wan teasing Ning Wanjia and feeling the soft body in her arms, Liang Yuan quietly smoothed out the complicated emotions in his heart, as if it was for Jiajia, so he should completely forget some things.

The next day, Tang Wan returned to Benxi, and the two little girls obediently returned to the military compound to accompany their grandfather. Liang Yuan was thinking about the signal system that Su Liangyu had created and went to the Science and Technology Park with Li Yuanling.

When I walked into Su Liangyu's office, I found that Su Liangyu was sorting out a large stack of documents. I looked at Liang Yuan coming in and said with a smile: "I just made a bet with Haiping that you will definitely come in the morning. Sure enough, I won. These are the minutes of the meeting held with railway signal experts in January. Xiaoyuan will know the whole story after looking at it."

Liang Yuan was too lazy to ask the reason why he used himself as a bet, and pointed to the document in Su Liangyu's hand and said, "Old Su, are these all, they look a lot."

"We have been in contact with there, but there was no result some time ago, so I didn't tell you." Su Liangyu said while handing the document to Liang Yuan.

Liang Yuan took the document and looked carefully page by page. Half an hour later, Liang Yuan closed the document and said with a long sigh. "Old Su, I really didn't expect that there are also bold, dedicated and ambitious people among the technicians of the Road Bureau."

In January, Liu Changhe introduced Su Liangyu to railway signal experts and a technician at Shengjing Railway Signal Factory under Shengjing Road Bureau.

There are two railway signal manufacturing enterprises in Shengjing, both of which are called Shengjing Railway Signal Factory. However, one of them has the word (road bureau) added to the official documents after Shengjing, while the other is a large central enterprise, a national key railway signal manufacturing enterprise built by the Soviet Union back then.

For Shengjing Road Bureau, the signal factory of the road bureau is the biological son. Although the other company is both an in-road enterprise, it only maintains a relationship of neither salt nor light. Only when the unified planning procurement of the Ministry of Railways and things that cannot be produced by its own signal factory will the road bureau have an intersection with Shengjing signal factory.

Therefore, when Liang Haiping proposed the upgrade plan for the 25S model undercarriage, the first reaction of the road bureau was to put good things into his own pot. Liu Changhe directly recommended the road bureau's subordinate companies to Liang Haiping.

The atmosphere was relatively harmonious when the two sides met for the first time. At that time, Liang Haiping was integrating the branch of the locomotive factory that was split into Shengjing that year. Although the strict management made countless people complain, for the sake of money, it was only limited to verbal complaints. The salary that was much higher than the road bureau still made the employees of the branch proud. At the same time, the image of the Northeast Locomotive Factory was greatly improved within the road bureau.

Therefore, the signal factory was very polite to Su Liangyu and others, and said whatever they had during the conversation, and answered the laboratory questions very carefully.

At the beginning, the two sides only limited the topic to the technology upgrade and transformation centered on the 25s model undercarriage. With the increase in later contact, the signal factory found that the main force of communication, Su Liangyu and others, and Northeast Locomotive, were all different. It can be said that the upgrade plan of the 25s model is entirely a plan to promote the ht680 chip developed by the chip laboratory.

Finally, the Road Bureau Signal Factory, which finally figured out the main and secondary, felt like it was treasured and became enthusiastic. Less than three days after the fact was found out, Pan Hong, the director of the signal factory, and Meng Xianda, chief engineer, visited Su Liangyu and proposed to develop domestic advanced railway signal control systems based on the chip laboratory th680 chip.
