It made a screeching sound in a disheveled manner.
Yang Qiwen coughed awkwardly and asked, "Principal Lin, please don't make fun of me."
Lin Shanshan: "I'm not kidding. This machine isn't perfect right now, but we can work together to improve it. We can make it a fully automatic robot vacuum cleaner that can follow the owner's commands and play music."
Yang Qiwen's eyes lit up as he listened: "Really? Can I participate in the research?"
"Of course, this is your idea, and you came up with the prototype as well."
The two also exchanged some professional opinions, such as how to overcome the technical barriers in intelligent perception and algorithm planning for robotic vacuum cleaners.
Gu Yiye had already come in. Seeing his wife talking, he waited quietly until night fell before he had to interrupt.
"Shanshan, it's time to go home for dinner."
Yang Qiwen and Lin Shanshan, who were in the middle of an exciting conversation, heard Gu Yiye's voice, looked outside, and then realized that it was already dark.
Yang Qiwen smiled apologetically and said, "I talked a bit too much about professional knowledge and kept Principal Lin from eating."
Lin Shanshan shook her head: "You haven't eaten either, go eat quickly. Tomorrow I'll find a few professional teachers to form a robot vacuum cleaner R&D team. Many hands make light work, and maybe we can develop the world's first robot vacuum cleaner in no time."
Lin Shanshan, who has studied knowledge for over ten thousand years, is full of confidence.
Yang Qiwen nodded excitedly, confident that it would succeed.
The three went downstairs. Yang Qiwen went to the cafeteria, where his wife, Liu Qinghong, had already prepared his meal. She asked:
"Why are you so late? Is there too much to clean today? Call me next time."
Yang Qiwen was still excited; it was something to be proud of that his research had been recognized.
He happily shared with his partner, "Principal Lin has decided to buy my patent for the sweeping machine and is also preparing to develop a fully automatic version."
Liu Qinghong was initially pleased, but then her face darkened, and she said, "We are able to study here thanks to Principal Lin. How can you still ask for patent money?"
“Didn’t we sign a contract when we came to the school? We are free students, and we can use 10% of the patent revenue to offset our tuition fees. I’ll take that and then give the school another 20% to cover both of our tuition fees.”
Yang Qiwen explained.
Liu Qinghong took a bite of braised pork and scolded, "Look at the food we're eating now, it's much better than what we eat at home. How can you have the nerve to say you'll only give us 20%?"
“I’ve made the decision. We’ll give it all to the school. Principal Lin has worked hard to build this school. We don’t want the money; consider it our way of giving back to the school.”
Women are more perceptive; they know schools have many expenses. Liu Qinghong analyzed this for Yang Qiwen:
"It can also help more rural students and students who can't afford tuition. This year, more than 1,000 students came, and they are provided with such good meals every day, plus teachers' salaries. Where would they not need money?"
"We'll be having more students next year, Yang Qiwen, so we need to be more aware of our responsibilities."
Yang Qiwen wasn't embarrassed by his wife's scolding; instead, he was very happy, gave her a thumbs up, and praised her:
"My wife is so good, beautiful and kind-hearted, and I always listen to her."
[So many lovely people have given me tips, thank you so much! This is recognition and encouragement for me.]
