The boy who specially came to report didn''t have the patience to solve it. He still wanted to go to see Shi Ning solve the problem.


    Hearing the speech, there was no good voice: "nonsense, you can''t solve it. You can still solve a page? Why don''t you try? I''ll convince you to write a line!"


    "Go and see, go and see! Oh shit! Shi Ning really knows how to solve! Last time Su Muhan and I saw her solve advanced mathematics problems with Lu Xueshen and Xi Xueshen!"


    I met him at the school English corner Pavilion and tried to challenge Shi Ning. Finally, I lost without fighting.


    The students who didn''t want to see it were all excited. 10 junior middle school students sat in car 13 and all came to car 14 under the orderly leadership of the teachers.


    One sat in the middle, wearing a pair of thousand layer cloth shoes and an old shirt with velvet edges when it was washed to the edge of the collar. However, the still clean and tidy old man slowly put down his newspaper, took off his presbyopia glasses, rubbed his slightly dry eyes, folded the newspaper slowly, took it in his hand, supported the small table with one hand, and got up slowly.


    The old man should be in his early seventies, with gray hair and deep wrinkles on his face. Although he shows wind and frost, he is more wise.


    Although he is old, the old man''s back is like an unyielding green pine. It is straight and strong. There is a calm that allows it to collapse and remain motionless.


    This is not only an old man, but also a wise man.


    Nearby, a young man quickly got up and whispered, "Le Lao, I''ll accompany you."


    "No, no, I''ll go to the front and have a look. The students were very interesting just now. I''ll go and have a look." the elegant old man, who precipitated the years, was introverted and very wise, said with a smile: "they are all a group of junior high school dolls. They are so young."


    The young man also smiled and said, "well, they are all middle school students. They should participate in any competition. They should belong to the one with strong results."


    "The one with excellent results, good, good. Sit down. I''ll come after a look." the old man didn''t want the young people with him to follow, so he insisted on him to sit down.


    The young man couldn''t help it, but he was still worried, "no, I''ll send you there, but the tutor told me again and again to take good care of you."


    "Does your tutor treat me as porcelain? Porcelain sometimes bumps. I''ll criticize him later. It''s unreasonable!" the old man pretended to be angry and really bluffed the young man.


    Then, the old man said, "you look at these materials. It''s more important than me!"


    With that, the old man, who was respected as "Le Lao" by young people, walked slowly towards car 14 with his hands on his back and a victorious smile.


    The bus is not crowded. If it is really crowded, a large number of passengers will get on the bus only at Nansheng station. The old man with negative hands walks to carriage 14 without looking. At a glance, he sees a group of students in school uniforms surrounded by two rows of seats. It seems a little nervous. A student doll is so nervous that he bites the back of his hand.


    Freshman high mathematics competition question, Shi Ning, junior high school doll or senior high school doll?


    The old man approached. Because his sight was blocked, the old man slightly lifted his toes and looked. There were too many student dolls around. He couldn''t see clearly when he lifted his toes.


    The more you don''t see clearly, the more interested the old man is.


    All attracted a group of dolls participating in the competition, all with serious and nervous expressions. It can be seen that the dolls who are doing questions are very powerful.
