Siheyuan: Selling antiques? Only making 28,000 RMB from 30,000 RMB

Jia Dongxu was so angry that his face turned blue: "I saw her take my radio with my own eyes! If I hadn't discovered it in time, she would have definitely sent it to you."

Zhou Dong stood in his simple hut, his eyes fixed on the equipment in front of him. He had just adjusted a few parameters and was now listening to the latest news broadcast. Suddenly, a sharp hissing sound interrupted his concentration, and he snapped back to his senses and found that the kettle on the stove had boiled dry and the water had spilled all over the floor.

"Oops!" Zhou Dong slapped his forehead, quickly turned off the fire, and then frantically looked for a mop.

At this time, Qin Huairu happened to walk in. Seeing this scene, she hurriedly said, "Zhou Dong, you are really so careless! The water has been boiled dry!"

Zhou Dong smiled awkwardly: "Sister Qin, I'm sorry, I was so focused on listening to the news just now that I forgot about the water on the stove."

Qin Huairu walked over, picked up the mop, and began to help clean the water stains on the floor: "You, being too involved in something is not a good thing, be careful."

Zhou Dong looked at her gratefully and said, "Thank you, Sister Qin. I am sorry to bother you."

Qin Huairu smiled and shook her head: "It's okay, it's just a small matter. Your equipment is really amazing. Not only do our neighbors like it, but I also think it's quite new."

While helping to clean up, Zhou Dong said, "Sister Qin, you can come and listen to the news often in the future. In fact, this equipment can be improved a lot, but sometimes I am too busy to handle it alone."

Qin Huairu's eyes flashed with curiosity: "Oh? Do you have any ideas for improvement? Tell me."

Zhou Dong put down the mop and pointed at the device and explained: "For example, you can add a timer function so that you don't have to turn it on and off manually every time; there is also voice recognition technology that can control the device through voice, and you can even pre-record some news clips and play them at any time."

Qin Huairu listened carefully and nodded: "Zhou Dong, you really have some ideas. But these functions sound very complicated. They require a lot of technology, right?"

Zhou Dong smiled and said, "Yes, but as long as we have time and energy, we can always get it done. The main reason is that the current conditions are limited and some components are hard to find."

Qin Huairu looked at Zhou Dong thoughtfully: "Zhou Dong, have you ever thought about turning these ideas into reality, or even promoting them?"

Zhou Dong was stunned for a moment, then shook his head: "I haven't thought that far yet, right now it's just for the convenience of everyone."

Qin Huairu's eyes became firm: "Zhou Dong, you really should consider it. You have the ability and talent, don't waste it. Otherwise, let's find a chance to have a good chat?"

Zhou Dong nodded: "Okay, Sister Qin, let's find some time to talk about it in detail."

At this time, there was a knock on the door. Zhou Dong and Qin Huairu looked at each other. Zhou Dong walked over to open the door and found that it was the brothers Liu Guangtian and Liu Guangfu.

"Zhou Dong, we are here." Liu Guangtian said with a smile.

"That's great. We have some questions to ask you," Liu Guangfu added.

Zhou Dong nodded: "Okay, come in."

The two brothers entered the house and saw Qin Huairu. They greeted her politely: "Sister Qin is here too."

Qin Huairu smiled and nodded: "Yes, Zhoudong is lively here, I want to join in the fun."

Liu Guangtian and Liu Guangfu sat down, and Zhou Dong placed the equipment in front of them: "If you have any questions, just ask, I will do my best to answer them."

Liu Guangtian pointed at the equipment and asked, "Zhou Dong, how do we adjust the antenna for receiving signals? We tried several times, but the signal is not stable."

Zhou Dong patiently explained: "The angle and height of the antenna are critical. It is best to place it in an open area and try to avoid metal objects. At the same time, you can try to adjust the direction of the antenna to find the location with the strongest signal."

Liu Guangfu nodded thoughtfully: "What about the power supply of this equipment? Sometimes we encounter the problem of insufficient power supply."

Zhou Dong pointed at the power module and said, "You can check the power line to make sure it is in good contact. If conditions permit, you can consider using a more stable power source, such as a transformer or battery."

He said gratefully: "Zhou Dong, you are amazing. We have been trying to solve these problems for a long time, but I didn't expect you to solve them with just a few words."

Zhou Dong smiled and said, "Actually, these are all based on experience. You can find a solution by trying a few more times."

Qin Huairu interrupted, "Zhou Dong, have you ever thought about giving a small class to teach everyone these techniques? I think many people would be willing to learn."

Zhou Dong thought about it and nodded: "This is a good idea. If everyone is interested, I can organize a small class to teach everyone some basic knowledge."

Liu Guangtian and Liu Guangfu said excitedly: "Great, we will definitely participate!"

Zhou Dong smiled and said, "Okay, that's settled. Let's find a suitable time and study together."

At this time, there was another knock on the door. Zhou Dong opened the door and found that it was Jia Zhang. She looked unfriendly and pointed at Zhou Dong's nose and started to scold: "Zhou Dong, you kid, what the hell are you doing? You made our family unable to sleep well at night!"

Zhou Dong frowned and said, "Jia Zhang, my equipment does not interfere with other people's lives. What do you mean by that?"

Jia Zhang sneered: "You play those crap every night, making our whole family unable to sleep! You are disturbing the neighbors!"

Qin Huairu quickly advised: "Jia Zhang, Zhou Dong's equipment is very quiet and it is impossible to affect your rest. Do you have any misunderstandings?"

Jia Zhang said angrily: "Misunderstanding? He made the signal of our radio unstable. You say this is not his fault?"

Zhou Dong shook his head helplessly: "Jia Zhang, my equipment does not interfere with the functions of other electrical appliances. The unstable signal of your radio may be another problem."

Jia Zhang refused to give in: "Humph, I don't like this thing of yours anyway! You'd better put it away quickly, or I'll go to the neighborhood committee to complain about you!"

Zhou Dong sighed, feeling helpless: "Jia Zhang, you can complain, but I guarantee that there is no problem with my equipment."

Seeing Zhou Dong's firm attitude, Jia Zhang threw her sleeves in anger and said, "Okay, wait, I will definitely ask the neighborhood committee to check it out!"

After Jia Zhang left, the room became quiet for a while. Qin Huairu sighed: "Zhou Dong, Jia Zhang is not easy to deal with, you have to be careful."

Zhou Dong nodded: "I know, but I won't give up my research just because of her unreasonable behavior."

Liu Guangtian and Liu Guangfu looked at each other, and Liu Guangtian said, "Zhou Dong, we support you. If you need any help, just let me know."

Zhou Dong looked at them gratefully.

At night, Zhou Dong sat at the table and thought carefully about what happened during the day. He knew that although his invention was recognized by his neighbors, it also caused a lot of trouble. Especially people like Jia Zhang, who would bring a lot of trouble to his life.

Just then, there was a gentle knock on the door. Zhou Dong walked over and opened the door, and found that it was Qin Huairu. She was holding a bowl of hot soup in her hand and said with a smile: "Zhou Dong, I made some soup and brought it to you."

Zhou Dong took the soup gratefully: "Sister Qin, thank you so much. You are so busy but still think of me."

Qin Huairu smiled and waved her hands: "It's just a small matter, don't be polite. By the way, Zhou Dong, don't take what happened today to heart. Jia Zhang is just that kind of person, don't pay attention to her."

Zhou Dong nodded: "I understand, thank you for your concern."

Qin Huairu sat down and asked with concern: "Zhou Dong, what are your plans for the future? Do you have any specific goals for the research of this device?"

Zhou Dong pondered for a while and said, "In fact, I have always wanted to apply these technologies to more fields, such as home automation, medical equipment, etc. I think technology can change our lives and make it more convenient."

Qin Huairu nodded, with admiration in her eyes: "Zhou Dong, your idea is great. I believe you will succeed."

Zhou Dong smiled slightly: "Thank you, Sister Qin. With your support, I will work harder."

In the next few days, Zhou Dong began to prepare for his "Science and Technology Classroom" and planned to share his technology with his neighbors. Qin Huairu also actively helped and sorted out some materials and tools, and the preparation work went very smoothly.

One evening, Zhou Dong and Qin Huairu were setting up the lecture venue in the yard when they suddenly heard a noise coming from outside the door. Zhou Dong went out to see Jia Dongxu and a few others gathered together with unfriendly faces.

Zhou Dong

As night fell, Zhou Dong stood at the gate of the courtyard and lit a cigarette. He took a deep breath, looked at the sparse stars in the sky, and his thoughts drifted far away. He thought of his grandma and grandpa in the countryside. They were old and their health was getting worse. Zhou Dong had always wanted to bring them to live in the city so that he could take good care of them, but this idea was opposed by many neighbors.

"Zhou Dong, are you smoking here?" Qin Huairu walked over and asked softly when she saw Zhou Dong looking thoughtful.

Zhou Dong came back to his senses, put out his cigarette, and sighed: "Yes, Sister Qin, I have something on my mind, so I want to smoke a cigarette to relieve my boredom."

Qin Huairu looked at Zhou Dong with concern: "Zhou Dong, tell me what's on your mind, I'll give you some advice."

Zhou Dong hesitated for a moment, and finally said: "Sister Qin, I have always wanted to bring my grandma and grandpa from the countryside to live in the city. They are old, and I am worried that it will be inconvenient for them to live in the countryside. But..."

Qin Huairu nodded: "But you are in trouble, right?"

Zhou Dong smiled bitterly and nodded: "Yes, many neighbors in the yard objected, saying that the yard is not spacious to begin with, and it would be even more crowded with two more people. Some people are also worried that there will be conflicts due to different living habits."

Qin Huairu sighed: "Zhou Dong, the neighbors' worries are not without reason. However, I think you should still take them in. After all, it is your responsibility to take care of the elderly."
