It's not dark yet.
It's time for another day of study.
After Cheng Zhao officially became the father of four children, he became more particular in class.
He stood, and the four boys sat, shaking their heads and reading the Three Character Sutra with him, over and over again.
Wu Huiniang was not idle when she was lying on the bed. She also read with Cheng Zhao. Dashan's mind was moving slowly, so she had to help memorize a few things. When Dashan asked her at night, she could remind her.
Cheng Wanwan locked herself in the back room and pulled out the thick agricultural book from under the bed.
The first half of the book is an introduction to the history of locusts, the disasters and turmoil caused by locusts from ancient times to the present, etc. It is only on the 300th page that it begins to formally describe how to control locusts, but it keeps talking about how to prevent them, such as the development of water conservancy, Planting crops such as soybeans that locusts won't eat, and then raising a large number of chickens and ducks in advance...it's too late.
Finally, pesticides were mentioned. The use of pesticides can drive away locusts. However, because pesticides will remain in the fields, affecting the nutrition and taste of rice, and are not in line with the concept of green environmental protection, modern agriculture generally does not use this method.
But in ancient times, as long as there was something to eat, who cared whether it was nutritious or not.
But taking out the pesticides is also a big trouble, and Zhao Youjin cannot be allowed to take the blame again.
The sound of reading outside the door stopped, and Cheng Wanwan had to put down the book temporarily. She was going to teach arithmetic class.
"Sanniu, let me test you first. What is thirteen plus four?"
Zhao Sanniu's forehead was covered with sweat.
He calmed himself down and stretched out his fingers to count. When he found that there were not enough, he borrowed Zhao Sidan's fingers.
Cheng Zhao asked him curiously: "Sanniu, what are you doing?"
"Count." As soon as Zhao Sanniu opened his mouth, he forgot where he had counted and had to start again, "Eleven, twelve, thirteen, count four more... I understand, mother, it is ten." seven!"
Cheng Wanwan almost shed tears of emotion, Sanniu finally decided to forget it, and her hard work for teaching for so many days was not in vain.
When she was about to continue teaching, Cheng Zhao walked into the back room quietly, opened the box and took out an abacus.
As soon as he took out the abacus, Zhao Ergou's eyes lit up. Every time he went to town to deliver goods, he could see a small abacus hanging on the shopkeepers. With a few fingers, he could calculate the total. He was almost envious of how much money was needed for the goods.
Cheng Zhao said: "From now on, if you do calculations, use an abacus and you don't need to count on your fingers."
Cheng Wanwan quickly gave up her position.
Cheng Zhao is simply her savior.
She has actually wanted to teach bead arithmetic for a long time. It is difficult for enlightened children to learn addition and subtraction, but they can learn bead arithmetic very quickly. Once they learn how to dial the bead arithmetic, they can instantly get answers to arithmetic involving hundreds, thousands, or tens of millions.
However, the original person is illiterate. She is inexplicably good at arithmetic and loses her character. Moreover, she is not very good at it and is afraid of misleading others.
Cheng Zhao placed the abacus on the table and said in a calm voice: "Let's take a look at the structure of the abacus first..."
The four boys were all serious, eagerly absorbing unfamiliar knowledge. Zhao Ergou even touched it twice. A strange feeling spread from his fingers to his heart. When he looked at Cheng Zhao, his eyes finally disappeared. resist.
Cheng Wanwan walked out of the main room quietly and went to the kitchen to boil water for the children to take a bath later.
As soon as she walked outside, she saw a dark figure lying at the base of the wall. She was startled. The dark figure raised its head and revealed Zhao Tiezhu's face.
"Aunt, it's me." Zhao Tiezhu said very uncomfortably, "I, I just want to hear what cousin Cheng is talking about, I'm leaving right now..."
Cheng Wanwan walked over and said softly: "If you want to learn, just go in and learn together."
Zhao Tiezhu blinked his eyes and said hesitantly: "But, but my grandma will definitely be reluctant to let me bring one egg a day..."
Cheng Wanwan chuckled: "Go in and ask Cheng Zhao if he is willing to teach you. If he is willing, it doesn't matter if he doesn't take the eggs."
Zhao Tiezhu rushed in immediately and said with bright eyes: "Cousin Cheng, can I learn to read and count beads with you? I, I will convince my grandma to pay for repairs. She may not be able to produce eggs, but she should I wonder if I can give you a bundle of dry firewood?"
Cheng Zhao said repeatedly: "There is no need to pay for the repair. Just sit down on a stool and listen together."
The second aunt has already paid five taels of silver as a salary. He teaches four students and teaches five students. It doesn't make much difference to him.
A few boys particularly liked bead counting, and they pestered Cheng Zhao for nearly an hour before giving up.
The night became darker and heavier, and Cheng Wanwan woke up in the middle of the night.
She quietly walked out of the yard, walked to the big locust tree, dug out the wires that had been buried under the big locust tree, then filled the hole, and then took down the solar panel from the firewood pile. She took it back to the yard. The long wire was hidden in the front wall, covered with hay, and the solar panels were placed on the roof...
"Second aunt, what are you doing?"
A voice sounded behind him, and Cheng Wanwan was so frightened that his three souls almost came out of their bodies.
She took a look in front of her and saw that the wires had been hidden, otherwise it would be difficult to explain. The solar panels on the ground were not clearly visible in the dark night. Cheng Zhao should not suspect anything...
She turned around with a smile: "Why are Zhao'er awake? Go back and sleep for a while."
Cheng Zhao vaguely saw that Cheng Wanwan was sweating profusely and panting from exhaustion. In the middle of the night, the second aunt actually got up to work, which was harder than he imagined.
How could he accept the money given by his second aunt with peace of mind before?
"Second aunt, let me help you."
He bent down and picked up the solar panel from the ground.
He frowned: "What is this?"
It feels strange in the hand. It's neither wood nor iron. It doesn't look real under the moonlight.
"Ahem, it's something to keep out the rain." Cheng Wanwan said casually, "Dashan Ergou and the others are tired during the day, so I plan to do this work myself. You can help Ergu put it on the roof. Later, we can go downstairs." It won’t leak if it rains.”
Cheng Zhao did not doubt his presence and helped Cheng Wanwan put the things on the table.
After finishing his work, Cheng Wanwan calmly went back to sleep.
Cheng Zhao's floor bunk was originally in Cheng Wanwan's room, but Zhao Sanniu snored too loudly, so he made an excuse and moved the bunk to the main room and slept on the floor in the middle.
This was the second night at Cheng Wanwan's house. He tossed and turned and finally fell asleep.
When the rooster crowed for the first time, Cheng Zhao sat up. He packed up the hay on the ground, rolled up the bedding and put it in the back room, and then went to wash clothes.
The lecture was too late yesterday and he didn't have time to wash the clothes he changed out of. Sidan told him that in this family, he could only do his own things without anyone's help.
When he was in the academy, there were employees from the academy who collected and washed his clothes. When he was at home, his nanny would wash them for him. It could be said that he had never washed his clothes before. He put the clothes in a basin and kneaded them a few times, and then kneaded the yellow mud off. When it's done, hang it to dry by the wall of the yard.
After he went to do other things, Wu Huiniang silently pulled off his coat, added a little plant ash, rubbed it and washed it until it was clean and white, and then hung it up to dry again.
