Li Qihua has no big ideals in her life, she knows that she is not capable, it is impossible to be a mathematics researcher, and it is difficult to even be a high school mathematics teacher. In order to avoid misleading her children, she did not choose to work in a middle school, and she was very good as a primary school mathematics teacher...... Most of the students who won the Olympiad Mathematics Award at Pingnan Primary School came from her disciples.

In addition to wanting to bring out a group of mathematicians for the country, Mr. Li has nothing else to ask for in this life.

- Grandma, you really brought me a pillow when I was sleeping!

"Haha." Limu laughed unconsciously, "Grandma, don't worry, I can't do the middle school Olympiad, but I still have the confidence to win the first place in the elementary school Olympiad." ”

He was a little ashamed to think that he was going to compete for the first place with elementary school students, and to squeeze a student out of the competition. I can't help but think too much about it, so let's laugh and bring it over first.

"Are you sure you want to participate?"

"Hmm." Riki affirmed.

"Then I'll tell you about the precautions. The preliminary round of the Mathematics Olympiad is held in March, then the semi-finals at the municipal level in May, and finally the national finals in July. According to the regulations, the age of the primary school group is 10~12 years old, because there have always been 12 and a half years old, nearly 13 years old children participated, so you can say that you are 10 years old this year, remember to insist that you are 10 years old when you compete. ”

"Eh, ......"

――How can you be so troublesome......

Riki began to regret that she had agreed too quickly.

I remember that I was in the third grade, and at this time, half of the class was of age to compete. Suddenly, one day, the math teacher, Mr. Liu, began to persuade students to participate in the Olympiad math competition. When I was promoted to the sixth grade, the Olympiad was reformed, and the division of the group became "grade group + age group", so that the grouping could ensure fair play at the same age.

At present, there are only five grades in the more backward places in the country, and there are six grades in the more developed areas, such as Shanghai, and the advanced cities such as Shanghai have six grades, so it is not possible to adopt the division method of grade groups, and the rules of age group participation are still adopted throughout the country.

"Grandma, which cup are you participating in this time?" Riki asked, tilting her head.

As we all know, there are many Mathematics Olympiads in the world, in China. What is the Spring Festival Cup, the Giant Cup, the Hope Cup, and the Hua Luogeng Cup...... Cities are vying to hold it, and the organizers only need to pay for one preliminary round to win a lot of money. The winter revenue fee of the National Olympiad has reached an astonishing 2,000 yuan/person!

Contrary to the domestic Olympiad competition, the World Mathematics Olympiad aims to compete rather than make money, not only not to make money, but also to lose money. In 1980, when it was Mongolia's turn to host the competition, Mongolia could not afford to pay for it, so the International Mathematical Olympiad was suspended.

Since then, the qualification test for the Olympiad International Competition has become more and more stringent, and there is no money to hold it.

There are naturally a wide variety of international Olympiads, such as the Asian Olympic AMO, the World Olympiad WMO, the International Olympiad IMO, and the American Invitational umo...... If you want to talk about which is the most authoritative, it must be IMO that is internationally recognized. Winning a gold medal at the International Mathematics Olympiad is tantamount to a national athlete winning a gold medal in the Olympic Games every four years.

What disgusted Riki was that participating in the International Olympiad in China not only had to participate in the "player training camp", but also had to pay a considerable amount of money.

"Limu, this time we are participating in the 'National Olympic Mathematics Competition', if you can be looked at after the competition, grandma hopes that you can continue to participate in the 'International Mathematical Olympiad' after leaving Pingnan, grandma will pay for you-"

If nothing else, at the end of June and the beginning of July this year, Limu will have to graduate from Pingnan. Before entering middle school in September, Riki was still a student at Pingnan Elementary School for the time being.

"Hey......" Riki sighed.

Athlete training is a time-consuming and laborious task.

――Grandma, I have a special task to complete, I don't have the confidence to win the first place in the International Olympiad in the middle school group, and it is a waste of time, so I can only take the first place in the country to give you the errand......

――I will try my best to fulfill your wish and leave a good memory of your teaching life.

"Hah...... Since that's the case, then help me sign up, grandma, do you have any exam questions from the previous year? I think it's better to do a few questions first to get used to the rules of the questions. Riki breathed a sigh of relief when she made her decision.

"Well, yes. I have it in the early years, and I'll give it to you when I get out of school later. Li Qihua smiled wistfully.

Mr. Li's dormitory is on campus, and you can see it when you walk through the school road and look up. That apartment was the teacher's dormitory in Pingnan, and when Limu returned many years after graduation, the apartment had become a temporary resting place for teachers. In the future, only teachers who can't make money and can't afford to buy a house outside will continue to live there.

Riki has also been to her dormitory a few times recently, and she has taken Katsuo, who is a bodyguard and servant. The first time, it was Grandma Li who was suspicious of Katsunan's attitude towards Limu too respectful, and asked the two to talk to each other. Riki briefly introduced Katsuo's employment relationship with herself, and Grandma Li did not object.

This time, Grandma Li needed to move the bottom of the bed and turn over the test papers, all of which was hard work. Naturally, he had to wait for Da Shengnan to finish the exam, and bring this big man who often moved bricks at the construction site to help.

In fact, due to the alleviation of family difficulties, Da Shengnan can add meat and vegetables to the family from time to time, and often see the happy smiles of his sisters and mother. And because of my mother's strong instructions, now I have reached the point where I follow Limu like a shadow. If the little employer had disappeared before her eyes and had not sat down at the door to paint, I am afraid that she would immediately have turned in her roll and looked for Limu.

When the time came, the bell rang for the end of the exam, and Da Shengnan ignored the sigh.

Packed up and quickly ran to the door, put the painting bag on his broad shoulders, and took Limu to the fourth class of the third year to find Lu Wei. Originally, he was supposed to go home from school as usual at this time, but Teacher Li waited under the dormitory on the side of the school road early and beckoned to the three of them.

Riki took Lu Wei and Katsuo to follow.

Grandma Li's room is on the second floor of the school dormitory, which is the last room in the dormitory corridor. Her door is a white door with wood lacquer, and there are yellow ears of rice hanging on the side of the door, and the brand-new Spring Festival couplets have long been pasted on the door.

Walking into the door, her room is not big or small, one bedroom and one living room are just right for two people. However, Principal Xu seems to prefer the environment outside the school, and only Grandma Li often spends the night here. She and her husband have another house outside, and in order to help students tutor, she only goes back to live with her husband on Saturdays and Sundays.

Riki followed her into the bedroom. In the bedroom, next to the mahogany vanity mirror, is an old pear blossom wooden bed. The carpenter made the bottom of the bed very high, and under the bed slats were several large chests that were also made of pear blossom wood. It's not anything valuable, it's all Grandma Li's collection of past exam questions.

…… There may also be textbooks and teaching documents from previous years.

The dormitory was built by the school ten years ago, and Grandma Li's furniture is out of place with the "new dormitory", and the oldest resident of the whole building probably belongs to her.

Grandma Li can be said to be the chronicle of Pingnan Primary School. Before Pingnan Primary School was divided and the new teaching building was located in Pingnan District, when the school was still called Nanhua Primary School, Grandma Li was already a teacher in the primary school. At that time, she taught not only mathematics, but also often had to go to the lower grades to teach pinyin, and made a cameo appearance as a Chinese teacher for a whole year.

As a teacher, you have to prepare lessons, what is in each lesson, every day, every week, every month...... How to arrange the 23 weeks of a semester, she needs to prepare two classroom teaching plans in advance.

"Teacher, you've worked hard—"

After waiting for the black tower mountain-like Dasheng man to pull out the box and push the box back under the bed. Riki took the past exam questions and stood at the door and bowed sincerely.

Although Ms. Li used to be only his substitute teacher, and this year she has only taught herself for a year at most, she is a respectable teacher.

“――！” Li Qihua raised her head in surprise.

Limu uses the title not "grandma", but "teacher". This is an affirmation of herself, her profession, and the cause she does.

She has been a teacher all her life, she doesn't make much money and enjoys much, but what she does is not in vain.

His sincere bow was not faked in the slightest.

“…… Yes...... Riki, what are you doing, the teacher is not hard, not hard...... It should be, and it's Katsuo who contributes......" Li Qihua suddenly felt cramped and uneasy, a little moved, and a little inexplicable.

…… The tears that appeared in the corners of his eyes were a little inexplicable.

"Teacher, hard work!" Da Shengnan saw that his employer couldn't bow his head, so he also bent down.

"Teacher's hard work!" Lu Wei shouted in a panic as if she had done something wrong. Seeing that she was the only one who didn't call "the teacher hard", she couldn't panic when she looked around.

Riki straightened up and touched the hair on the top of her head, and the little girl did the same, but forgot to bow her head and bend down to show her respect. However, Grandma Li has not substituted for the fourth class for the time being, and her hard work can be regarded as calling three years in advance.
