"Ask your sister." Peng Qinghong said to his son.

Qiqi said: "Sister can't either."

When her son said that her sister didn't know anything, Peng Yujiao picked up the questions of her son doing homework and looked at them, sighing: "Mathematics problems." As she said that, she handed the mathematics problems to Xiao Yingying who was near her: "Aren't you going to go to Capital Normal University to teach elementary school mathematics? Look. I'm really not good at math, but Chinese is OK."

Xiao Yingying took the question book and looked at it pretentiously: "This question is very simple. The answer - wait a moment, I will calculate it, I said, what grade he is in elementary school this year, has he already done such a difficult question?"

"He is in the fourth grade of elementary school this year, in the United States."

"You gave him a foreign topic? He will study in China in the future, right?"

"You mean-" Peng Yujiao looked at Xiao Yingying strangely, "The education in China is far behind that abroad?"

"Impossible!" Zhao Fengying immediately interrupted, "We pay great attention to children's education in China, especially in educational research in mathematics, physics and chemistry. Xiao Yingying, don't talk nonsense if you don't know."

Xiao Yingying glared at her eyes: "You can understand if you haven't read the education? Look at this question, can you do it? Didn't you say that his sister can't do it either? How old is his sister?"

"His sister is only one year apart from him, and she is in the fifth grade of elementary school." Peng Yujiao said.

Xiao Yingying choked for a moment.

Zhao Fengying took the opportunity to take away the homework questions in her hand and gave them to Ning Yunxi beside her: "Teacher Ning, look, is this a primary school math problem?"

Ning Yunxi glanced at the question and quickly judged it: "Yes."

"Look. Teacher Ning said that it is a primary school student's problem. You can't do it!" Zhao Fengying said, pointing his finger at Xiao Yingying again.

Xiao Yingying was furious: "When did I say I couldn't do it anymore? I mean that even if I could do it, I didn't use the mathematical formulas of primary school, which exceeded the child's primary school learning outline. This is not a primary school problem at all."

"You can do it and have a look." Zhao Fengying threw the pen directly to her.

In front of everyone, Xiao Yingying had to pick up the pen, write randomly on the draft paper, and then concluded: "The answer should be twenty-six."

"No, the answer is twenty-three." Ning Yunxi said.

Xiao Yingying turned her head and glared at Ning Yunxi.

Zhao Fengying asked the child: "Is there a standard answer?"

"Yes, the answer says twenty-three, but there is no answer process. We don't know how to calculate it." Qiqi said.

"Look, Teacher Ning's calculations are right, you are wrong. What else do you have to say?" Zhao Fengying said to Xiao Yingying.

"I want to see how she tells the child!" Xiao Yingying threw the pen to Ning Yunxi, but she didn't believe in this evil, "I have never seen such a primary school problem anyway."

"Because this is an Olympic competition topic," said Ning Yunxi.

In this era, the domestic awareness of Olympic competitions has not yet been in line with international standards, and no one has participated in such international competitions, let alone introducing such education in China. However, it is not surprising that Qiqi and the others have been exposed to such topics before studying abroad.

After Ning Yunxi said this, everyone understood it all at once.

Xiao Yingying was stunned for a moment and jumped up: "Do you understand the Olympic competition questions?"

Ning Yunxi and she attended a school where she had never learned this type of mathematics teaching. Where did Ning Yunxi learn it?

"Because Teacher Ning is diligent in studying outside the classroom, keeping pace with the international community, and striving to improve his education level." Zhao Fengying raised her head to Xiao Yingying: On the other hand, someone is you, what are you doing? Anyway, he is doing things that are not doing his job properly, no wonder he is worse than Ning Yunxi.
