Siheyuan: I earned foreign exchange in the heyday

Following the notifications from various street offices in Sijiu City, the civilian population of Sijiu City was almost in chaos.

Many people can talk freely about national affairs or even international situations when they hear about them in newspapers or from other people. They do not allow others to refute them and are full of vigor and enthusiasm when they make comments.

However, when faced with such national affairs that are closely related to oneself, people become completely irrational.

For a time, each street office was surrounded by people in three layers.

No matter how clear the notification is, there will always be some people who go to the subdistrict office afterwards, hoping to explain their family's difficult situation to the subdistrict office.

I hope that I or my family can become the most special one in the entire street office or even the entire city.

Chen Changan was also helpless about this. The country couldn't do anything about it, let alone Chen Changan.

This is the power of nature. Chen Changan is not at the level to fight against nature by himself. He can only believe in the country and will eventually get through the difficulties.

At the Sijiucheng Motorcycle Factory, as the workers become more familiar with the parts they process, their speed is getting faster and faster, and the daily output is steadily increasing.

Chen Changan's mind also slowly began to move away from the motorcycle factory. After all, apart from the beginning, there were some important changes.

When the factory began to operate slowly according to Chen Changan's ideas and systems, there were indeed fewer and fewer things that required Chen Changan's intervention.

The three-wheeled heavy-duty motorcycle that Chen Changan had started to design was officially completed. Although he knew that this three-wheeled motorcycle was definitely needed by the country.

But the process cannot be messed up, and this thing cannot be produced casually. Moreover, the tasks in hand have not been completed yet. Chen Changan plans to wait until the task of the two-wheeled motorcycle is completed before making a few three-wheeled motorcycles to test the waters.

Thinking that there would be three years of drought in the future, there was no hope for fishing, so while he was not busy, Chen Changan took his fishing rod and ran to the old place on Sunday to see if he could still fish there.

At the fishing spot, the water level has dropped a lot, but there are more people fishing.

Seeing that the water is not very deep, it is probably difficult to catch big fish at this time. After all, the water is shallow and not suitable for big fish to live in, and they have very strict requirements for the environment.

Now that I'm here, this may be the last time I go fishing in the next three years. No matter whether I can catch any fish or not, I'll just cast my rod.

The weather in September in Sijiu City was still very hot. Chen Changan fished for the whole morning but only caught a few small fish the size of a palm.

This alone is more than 90% of the fishermen around. Chen Changan stood up and wiped the sweat from his forehead.

I looked up at the sky. The sun was so bright, but there were a few clouds above my head.

So he said to himself, "It's such a big cloud. I wish I had an anti-aircraft gun. I could shoot it a few times and make it rain artificially, which would cool it down a bit. But unfortunately..."

"Anti-aircraft guns for artificial rainfall? What does that mean?"

Chen Changan heard someone talking next to him and turned around to see that Uncle Xiao was standing behind him, looking at him expectantly.

Now that I have met Mr. Xiao, I have a place to buy my Zhonghua cigarettes.

Uncle Xiao didn't care what Chen Changan thought, and quickly asked, "What did you mean just now? Artificial rainfall? Can we really make it rain?"

Chen Changan looked at Uncle Xiao's anxious expression before he finally reacted.

Now is a time of great drought in the country. As long as there is a little chance and hope, the country will always give it a try.

At least having a solution is better than sitting there helplessly waiting for death.

Chen Changan himself was also a little annoyed, because artificial rainfall in later generations was basically completed independently by the meteorological department.

In people's daily lives, artificial rainfall is not even a news item, so Chen Changan did not think about it for a while.

Uncle Xiao was watching Chen Changan fishing from behind and overheard it. This reminded Chen Changan that in this era, most people had never heard of the concept of artificial rainfall.

So Chen Changan said to Uncle Xiao, "Actually, the water in this river, when exposed to the sun, will turn into steam and fly into the sky."

He pointed to the three or four clouds in the sky that were about to merge into one. He continued, "Just think of it as flying into the cloud. There is a lot of water accumulating in that cloud. It will rain when it can't bear it anymore."

Uncle Xiao knew that Chen Changan was explaining the principle to him, and Uncle Xiao listened very carefully. Xiao Liu behind him had already taken out his notebook and was taking notes frantically.

Chen Changan continued, "But there is wind in the sky, and this cloud will be blown away. We can't control where it will be blown to and when it will start to rain.

But we can put something in the shells, or fly a plane over the cloud and drop something.

Speed ​​up the rain process. That’s what I call cloud seeding.”

Uncle Xiao nodded. Chen Changan explained it very clearly. The water on the ground flew into the clouds after being exposed to the sun. There was rain in the clouds but it didn't rain. Then what he needed to do was human intervention.

It's easy to understand and the logic makes sense. Now the key point is what to use to make the clouds rain.

After figuring it out, Mr. Xiao continued to ask hurriedly, "What do you need to put in the shells to make the clouds rain?"

Grandpa Xiao automatically ignored the plane spraying. After all, the country was already in trouble enough, and there were not many planes. During the National Day that year, the planes flew twice. It was still unrealistic to expect to use planes to popularize artificial rainfall across the country at this stage.

But anti-aircraft guns are different. After all, we captured quite a few of them in the war back then, and we are now making them ourselves.

It might be an exaggeration to say that there are anti-aircraft guns in every region of the country, but which military region doesn't have anti-aircraft guns?

Wherever there is drought or clouds, just pull the anti-aircraft guns there and start firing.

After listening to Mr. Xiao's question, Chen Changan thought for a while.

Uncle Xiao was a little anxious when he saw Chen Changan remained silent, and said, "Young man Chen, this is a matter concerning the fate of the country, and such matters cannot be kept back."

Chen Changan said aggrievedly, "Uncle Xiao, please give me some time to think about it. I can't just do whatever I want, right?

If I say something wrong by mistake, I will be a sinner of the country."

Uncle Xiao nodded when he heard this, and he knew that he was anxious. Things like this really can't be rushed.

Chen Changan mainly recalled and said, “As far as I know, there are generally two types of catalysts for artificial rainfall.

Dry ice and silver iodide. Both can be used as catalysts to achieve artificial rainfall.

It is also said that salt may work, but I am not sure, and this still needs to be tested by the relevant departments.”
