Xu Qing asked several carpenters to make some furniture. These carpenters are very skilled and often receive work orders. They are not willing to work without higher wages.

Xu Qing thought that if Cao Laoliu was here, he would not only save a cent, but also do better than these people.

Now Li Qinshu has to supervise the construction of the school every day and is very busy.

Xu Ying and Hao Wei look at the shop. As soon as Xu Qing is free, he goes to talk with shopkeeper Yun. There is no business, and shopkeeper Yun is very bored. Sometimes they can talk about a few kilograms of dried plum vegetables while they are eating melon seeds.

"I've heard that many men have joined the army, but there are also restrictions on the number of men. The owner of the family said that he wanted to enlist about 50000."

Fifty thousand sounds like a small number, but Xu Qing knows that in ancient times, when the population base was small, there were already a lot of people. Those who randomly sent millions of soldiers were all performed in TV dramas.

"Is the welfare of being a soldier particularly high?" Asked Xu Qing.

"No, when I come back from being a soldier for a year, my daughter-in-law will be able to marry me." Shopkeeper Yun said, "there are many people who have no place to stretch, and the work in the field doesn't need to be watched by so many people. People who come out of leisure naturally want to think about something else."

Xu Qing is chatting with shopkeeper Yun. Seeing Yu Boming coming back from outside, he doesn't look very well.

"What's the matter?" Asked Xu Qing.

"It's said that locusts have occurred in several States, and all the vegetables planted in the fields have been eaten by locusts," Yu said

"Locust?" Xu Qing was stunned and said, "why don't you catch the locusts and eat them quickly? After eating this piece of locusts, they will migrate. We have to catch them quickly before they leave!"

Yu poming and shopkeeper Yun's face are a little distorted, "can this thing be eaten?"

"Ah, it's delicious after frying. I've had it! Really Fearing that they would not believe it, Xu Qingsheng raised his voice. "When I was a child, my lord Well, my father has caught locusts, but they don't have enough to eat, and some people are allergic to it. "

Looking at their faces, Xu Qing snorted: "it's grasshopper. I used to eat oilseed insects when I was a child. It's fragrant after baking."

"Do you dare to eat now?" Yu Po Ming asked.

“…… I dare not

When I was a child, I was not afraid of anything. When an adult said she could eat it, she would dare to put it in her mouth. Now it's disgusting to dare not to eat it.

"It's not surprising that there are locusts after the drought. After all, the birds are gone. Without their natural enemies, these insects will become arrogant." Xu Qingdao.

"What can you do?" Yu Po Ming asked expectantly.

Xu Qing held his chin and thought, "well, the natural enemy of locusts is one. Let's see what birds eat locusts, so that people don't know to kill and eat meat when they see birds, and Locusts like to put out a fire at night. Moths put out a fire. You know, that's probably the virtue. So lighting a bonfire in the dark can lure and kill locusts. "

Yu Po Ming nodded with a smile: "I know. I'll send someone to tell Zhao Jian to send a message."

Shopkeeper Yun gave Xu Qing a thumbs up: "great!"

Xu Qing: "it's called knowing yourself and the enemy, winning every battle, observing the enemy's habits, finding out the enemy's weaknesses, and then making use of them. Even if I don't say it, someone will surely find out."

Shopkeeper Yun: "I don't know when to find out. Everyone is worried about the food eaten by locusts. They are so angry that they have the patience to observe the habits of locusts. Anyway, I'm very convinced with you."

Xu Qing: "but I didn't observe it. I learned it. I read it in the book."

In fact, it was said by the Chinese teacher in class. Xu Qing recalled her math knowledge in school these days. As a result, she recalled a lot of things. She never found that her memory was so good, and she still remembered things that were so long ago.

Outside the door, Li Tinghui comes to check Xu Qing with his homework. The two families are diagonally opposite. The little guy runs over by himself, obviously familiar with the way.

Xu Qing sweeps his homework, but he doesn't care whether it's right or wrong. Instead, he asks, "does hui'er like peas?"

Li Tinghui tilted his head and thought for a while before he remembered what peas were. He didn't remember the taste of peas, but there was no disgust in his memory, so he nodded hesitantly.

"Let's plant a small stubble of peas in the yard. The deadline is 100 days. You should write an observation diary of pea growth. The observation diary means that you should record every change of peas every day in detail."

If Duanmu rings here, we must ask what the meaning is, but Li Tinghui is just a child and doesn't care if what he does is meaningful.

"Come on, let's go home and plant peas and say goodbye to Uncle Yun."

"Goodbye." The little guy cleverly waved to shopkeeper Yun.

"Oh, take your time. Come here often!" Shopkeeper Yun also waved his hand.

Back home, Xu Qing took a hoe to the yard and let Li Tinghui choose a place by himself. Finally, the little guy chose the land under the eaves near his windowsill.

While digging the ground, Xu Qing taught him why to dig the ground before planting vegetables, why to bury the land in the soil, why the seeds can't be buried too deep or too shallow

She knows that Li Tinghui is different from other children. He is autistic and introverted, so why is it up to her to ask, but after asking these questions, she will also ask him what he doesn't understand.Children are supposed to be a collection of 100000 questions about why. If Xu Qing doesn't take the initiative, he will probably hold back what he doesn't understand and never explore. What she has to do is to arouse his curiosity and thirst for knowledge.

However, if it is taught by other adults, it is probably a sentence that doing so can make the seeds germinate better, but Xu Qing explains more thoroughly why the seeds germinate, which has to start from the structure of the seeds and meeting the conditions for seed germination.

Waiting for the little guy can't bear to ask curiously: "how long can the seed germinate?"

Xu Qing kept the mystery and let him observe and summarize by himself.

So the next day, we saw a seven-year-old boy squatting under the eaves every morning staring at the bare soil in a daze for a while. In his arms, he held a thread bound book and a charcoal pen tied to the book. From time to time, he would open the book to see what was recorded in it, or add a few words to it.

In order to save time, Xu Qing's seeds were planted after seed selection and germination in advance, so after planting, they soon sprouted out of the soil.

"Elder sister, do you know that you can open up wasteland here?" Xu Ying asked.

"Yes, you want to grow food?"

Hao Wei nodded: "I want to plant some vegetables to eat at home, so I can save the money to buy vegetables."

Maybe there is no business in the store, which makes the couple feel uneasy. Xu Qing said, "the food they usually eat is not bought. Don't worry about the food. The business will be good after a while. Now everyone has no money."
