After saying that, Song Shuxi stopped talking to the four people opposite her. She took out an apple and started eating.
The other three were too embarrassed to talk to her.
After all, girls with short hair are with them. But they also decided to stay away from girls with short hair in the future.
At this time, people look down on the third party who destroys other people's families.
As dinner was approaching, the carriage became noisy and Wei Jianguo was woken up.
He might still be a little dazed after just waking up, so Song Shuqian handed him a kettle with spiritual liquid in it, and said, "Drink some water to wake up, and then go back to sleep at night."
Wei Jianguo hummed softly, still reacting.
After drinking a few sips of water, I slowly regained consciousness. "How long have I slept?"
"Three hours. You've been too tired lately and should have a good rest."
After Wei Jianguo woke up, he accompanied Song Shuxi to the toilet. It was so dirty that Song Shuxi went straight into her magic gourd. No wonder Wei Jianguo bought several spittoons and asked her to put them in the magic gourd.
Song Shuxi didn't look very well when she came out of the bathroom. Wei Jianguo knew the reason at a glance and found it a little funny. "It's okay, leave it to me."
Song Shuqian's face turned red all of a sudden, "I'll do it myself."
Wei Jianguo took her hand, not disdainful at all, "I am your husband, leave these things to me. Don't I also clean the toilets in our yard? It's the same."
Song Shuqian couldn't bring herself to do it, so she could only nod with a red face.
"Do you feel any discomfort in your stomach?"
"No, if you didn't remind me, I wouldn't have forgotten that there was another baby in my belly." This child is really easy to worry about. Since Wei Jianguo came back, he hasn't reacted at all.
The two returned to their position and it was already dark outside.
"It gets dark earlier here, I wonder if the sunrise is also earlier," Wei Jianguo found a random topic to chat with his wife.
Song Shuqian explained to him, "The time of sunrise and sunset is affected by the season and latitude. In winter, our country is near the perihelion, the daytime is short, the sunrise is late, and the sunset is early. In summer, our country is near the aphelion, the daytime is long, the sunrise is early, and the sunset is late.
Latitude also has an impact. In high-latitude areas, sunrise is later, sunset is earlier, and the daytime is relatively shorter. In low-latitude areas, sunrise is early, sunset is late, and daytime is relatively long. "
Wei Jianguo didn't understand, "What is latitude?"
"Latitude refers to the angle between a point on the earth's surface and the equatorial plane. Harbin's latitude is between 44 and 46 degrees north latitude; Huludao's latitude is between 40 and 41 degrees. This is just an approximate range. The exact range needs to be accurate to the second, but I don't remember it."
As Song Shuqian spoke, she explained to him using the small notebook she carried with her.
The longitude is also discussed.
It was half an hour later when I finished speaking.
Wei Jianguo likes his wife to tell him all kinds of things at any time. His wife is like an encyclopedia and he can ask her anything he doesn't understand.
You never know when these things will be used.
Even though their voices were very low, the four people around them heard a few words.
Stand in awe.
They had never heard of these things.
Even though schools are closed now, people with real insight will still admire intellectuals. The idea that all else is inferior except for reading, which has been held for hundreds of years, is not so easy to overturn.
After the couple finished talking, they started to eat.
Dinner is roujiamo, served with porridge, which can be eaten after heating it up in the same way.
Their eating was good but the flavor was minimal and did not attract the attention of others.
Instead, it was the cucumber that Song Shuxi ate after dinner that attracted an old lady.
She came over and started to act pitiful to Song Shuxi, "Girl, I feel a little carsick, give me one of your cucumbers."
Song Shuqian didn't let Wei Jianguo speak, and said with a smile, "Auntie, I'm pregnant, so I brought some refreshing food with me to relieve my pregnancy reaction. If it were normal, I would give it to you if you asked, a cucumber is not worth much. But now it's special, I don't bring much, and I can only afford to eat one after dinner to relieve my stress. You can go to the dining car and see if they have it."
The old lady looked at Song Shuxi's flat belly and asked, "Are you really pregnant?"
"That's not true. There was a reaction a few months ago."
The old lady left unhappily. If you try to snatch things from a pregnant woman, you will definitely lose.
Wei Jianguo really enjoys his wife's protection of him. He usually stands in front, and it feels good to be protected.
After dinner, the two of them still went to stand in the aisle.
It was completely dark outside and I couldn't see anything.
Song Shuqian looked at the darkness in the distance and didn't feel scared. Instead, she felt a little curious. She had read in storybooks before that there were all kinds of monsters in the wilderness at night. Of course she knew she couldn't say this out loud, so she just thought about it in her heart.
Worried that his wife might become emotional and have wild thoughts again, Wei Jianguo thought it would be better to let his wife give him a lecture.
"Wife, how does a train start?"
"The train we are riding now relies on a steam engine. There is a boiler on the train. Workers add coal into it, which heats water into steam. The steam enters the cylinder and pushes the piston to power the train. From a distance, the chimney on the train is always smoking."
The original owner, Song Shuxi, used to work in the design department of a machinery factory. She didn't get in through connections, but rather based on her real talent and knowledge. These simple mechanical principles were not difficult for her. After Song Shuxi came here, she digested all the memories of the original owner and studied them in more depth.
Therefore, these questions come to mind.
Maybe it's because men are naturally interested in machinery. After Wei Jianguo found out that his wife knew about these things, he pulled Song Shuqian to the bunk and continued to ask, "Wife, how do you control the speed of the train?"
"There are many ways to do this. One is to adjust the gear like a car. Cars have first, second and third gears, and trains also have them. The second is to adjust the steam supply. For a slight speed increase or decrease, you can adjust the throttle valve. For a large speed increase or decrease, you need to operate the steam valve. The third is emergency braking. There is an emergency brake handwheel, or air brakes. The last method is to control the pressure of the boiler, which means putting more or less coal.
There may be other things I haven’t thought of. If you are interested, you can ask the teacher when you have related courses later."
Wei Jianguo's eyes are sparkling as he looks at his wife. His wife understands everything.
"Wife, you are so awesome," Wei Jianguo said sincerely.
Song Shuqian casually drew a schematic diagram of the steam engine principle for him, which he kept as a treasure, intending to take a good look at it and remember everything his wife had said.
Song Shuxi was worried, "I'll keep it and give it to you when I get back."
Wei Jianguo had no objection.
Seeing that he really liked it, Song Shuxi drew him a diagram of the bicycle's structure and its principles. This should not be confidential, so he could take a look at it at will.
Just now we were talking about the steam engine. Their sound was very small and they were very close together, so only two people could hear it.
It was only at this time that Wei Jianguo found out that his wife was actually proficient in mechanics.
Song Shuqian did not have the courage to correct him. She was good at mechanical principles and had a photographic memory, so she remembered everything she had seen. However, when it came to operating something, she was at a loss.
It was already very late after the chat, and Song Shuqian wanted Wei Jianguo to lie down and have a good rest.
"I'll go to the middle bunk so you can protect me in the lower bunk. Anyone coming over here has to pass by you first," Song Shuqian insisted.
Wei Jianguo couldn't persuade her, so he carried her to the middle bunk and said, "Call me if you want to come down."
"Uh-huh".
