Xiao Zongchen looked at her deeply, turned around and left.

He felt that there was something wrong with what she said. Whatever you reply to doesn't seem appropriate, so you just don't say anything.

Chu Xi looked at his back as he left, a little inexplicable, blinking, full of doubts.

What is he annoyed about?

Squinting at Xiao Zongchen's broad and straight back gradually moving away, Chu Xi felt as if he had caught something, and pulled the thread to brush it over, a little suddenly.

The current person is introverted and decent, and one of the choices she seems to have given after thinking about it is to stay overnight, in his opinion, it is probably a behavior of Meng Lang?

Shaking his head, Chu Xi turned back to the ward.

At this time, only Chu Mingliang and Chu Mingguo were left in the ward, and the old man Sun was gone, and looking at the expressions of the two, it seemed that when she went out to see off Xiao Zongchen, the two of them had a detailed understanding of the original cause and effect, otherwise the atmosphere would not be so dull.

"Dad, uncle." Chu Xi called out to the two of them and sat down on the stool next to them.

The dawn and darkness in the northwest are two hours later than those in the capital. Although I have just eaten and chatted, it is still early to go to rest.

Therefore, Chu Mingliang didn't leave, and Chu Xi didn't leave.

The two of them looked at her too cautiously, Chu Xi sensed it, so he raised his eyes and asked, "Do you want to keep the New Year?" ”

Chu Mingliang didn't speak, he went to see Chu Mingguo first, meaning that he came to get an idea.

Chu Mingguo paused, nodded, and reacted most honestly.

Ask clearly to keep the New Year, it will be easy to do, Chu Xi took out a folded boxy paper from the pocket of his military coat, stretched it out, and said, "I found someone to get a few sets of Olympiad math papers, and if I am idle, I am idle, so I might as well do it." ”

She said it casually and naturally, but it shocked Chu Mingliang and Chu Mingguo.

Neither of them thought that they could live like this.

Chu Mingguo reacted first, "Olympiad? ”

He has been immersed in research, never left the base, nor to understand the development of mathematics in China, the only thing he can see is relevant scientific journals and journals.

Has this kind of foreign mathematics competition been introduced to China?

"How do you get this kind of paper?" Chu Mingliang was surprised, "Our domestic college entrance examination mathematics is not such a difficult ......"

So if you want to prepare for the college entrance examination mathematics, this kind of is not suitable.

Chu Xi opened the test paper completely, handed it to Chu Mingguo, and handed over a pen to answer the question he just asked, "Well, Olympiad." ”

Then he also gave Chu Mingliang the test paper and pen, and also answered his question, "Before I came here, I roughly understood that there were no entertainment activities here to pass the time, and it was cold and freezing, and it was not easy to go out, so I asked Aunt Zhou to get these." ”

Her eyes were sincere, and in the eyes of the Chu brothers, she was completely innocent and confused.

My children thought, what else can I do? For a while, I had to squeeze the test paper and pen in my hand.

Chu Xi saw the two of them looking at her and explained, "Each test paper is different, you can share a table." ”

Chu Mingliang felt that his mathematics level was not as good as his younger brother Chu Mingguo, coupled with his high school teaching experience, after listening to Chu Xi's words, his heart instantly shook.

Is this because they think that the two brothers can't copy the answers, so they are so comfortable letting them share a table?

"How many minutes does the exam last?" Chu Mingguo asked.

"Let's follow the standard length on the paper." Chu Xi shook the test paper and pressed the folds again, "It has been less than ten years since our country first participated in the Olympiad, and the popularity is not so wide, so let's do it first." ”

Chu Mingliang, a high school mathematics teacher, instantly thought of the results of the first time he participated in the Olympiad in China, and blushed a little.

"Actually," he took a deep breath and said to Chu Mingguo, who was listening carefully to Chu Xi, "Actually, it's much better now, and it's improving every time......

He was invited to participate in 1981, unofficially in 1985, and did not officially participate until 1986.

Once a year, in the three years of official participation, although the results are slightly behind, the progress can be seen with the naked eye!

Chu Xi paused for a moment, thinking that after this year, the top one or two Olympiad students are all Chinese, and nodded seriously, "Yes, it will get better and better." ”

Chu Mingliang took off the armor of protecting the students at this time, and returned to the appearance of an elder, "It will definitely get better and better, our school itself organizes student competitions, and occasionally a few brother schools will also play leagues, pay attention to it, it will be good." ”

"Chinese people have a kind of tenacity, either they don't do it, or they must do their best." Chu Mingguo nodded to his brother Chu Mingliang, "I believe that our country attaches great importance to mathematics. ”

Chu Mingliang's self-esteem as an excellent mathematics teacher in a key high school has finally recovered a little.

I don't care about the morning or evening, so the three of them wrote the test papers.

When Old Man Sun finished checking the room and came back again, he saw the situation in front of him, let alone his head, and his teeth began to hurt.

Whose family spends the New Year doing homework?!

"Are you passing the time? Or do you study it seriously? Old man Sun lifted the radio he was carrying in his hand and asked in a loud voice, "Then do you still use this radio?" ”

It has been ten years since the reform and opening up, and as soon as the economy went up, the materials were also abundant, and a large part of the people in the city had televisions, whether they were black and white or color, they were the same after all.

They also have televisions here, not many, usually for watching news broadcasts, and they don't have the conditions to install them in the ward.

He had a radio that could be tuned, so he brought it to them, thinking of passing the time, but the three of them had fun on their own.

Doing homework is really rare!

"Yes." Chu Xi put down the pen in his hand, stood up, and went to pick up the radio in Old Man Sun's hand.

The radio felt like it was forty or fifty centimeters long, and there were antennas on it, and there were a lot of buttons.

Chu Xi felt a little magical, and there was a sense of novelty in looking at antiques.

"Haven't seen it?" Old man Sun turned on the switch, and suddenly there was a sizzling sound from inside, and while adjusting the stage, he happily said to Chu Xi, who had strange eyes, "Let me tell you, this is ......"

Before he could say anything, he suddenly stopped.

He forgot that the girl in front of him was not only Chu Gong and his daughter, but also a businessman who had done business!

Rich!

"Have you ever watched color TV?" Old man Sun was transferred to the stage of the Spring Festival Gala and raised his gray-haired head, "What does it look like?" ”

Chu Xi looked away from the radio and thought for a moment before saying, "If you've ever seen a black-and-white TV, it's similar in appearance to a black-and-white TV, except that the image is in color." ”

"That's weird and amazing!" Old man Sun imagined it for a moment and nodded, "I really want to see it." ”

Chu Mingguo pinched the pen and looked up, smiled and said, "This is the inevitability of scientific development." ”

After speaking, he lowered his head again and seriously went to write the test paper that his daughter specially brought to him in her pocket.
