"No smarter than hard work," Cherie cried.

Hu Xiaoxiao is a very clever boy. In an exam, he answered all the questions correctly and was praised by the teacher, so he became proud and thought that he would be selected by the teacher to participate in the national Olympic mathematics competition. When he learned that Roy's mother was ill and Qin Fen wanted to take part in the Olympic Games to get funds to reduce the family burden, Hu Xiaoxiao immediately decided to help Qin Fen become smart and qualify for the Olympic Games.

But how can we be smart? At this time, Hu Xiaoxiao met an Olympian Lin Cong, and he promised to coach Hu Xiaoxiao to study Olympiad. Hu Xiaoxiao took his classmates Chang 'an and Roi to see Lin Cong, and the children visited Lin Congke. Lin Cong not only teaches children how to learn Olympic Mathematics, but also teaches them how to make money. And this way to make money is to let children go to the streets to make up sad stories to win the sympathy of others. How can the children know-they beg separately! Fortunately, Lin Cong's illegal behavior was discovered by the police and Lin Cong was arrested.

Just when Hu Xiao was depressed, he received a mysterious note, which led him to a mysterious tree hole. The secret of the tree hole was discovered by the classmate Xiao Cherry, so Chang 'an and Roi also knew the mysterious tree hole and mysterious person. The mysterious man asked the children to visit Jinghua University and arranged a "glasses brother" to be their guide. Here, the children not only saw the hard-working students of Jinghua University, but also learned many stories of hard-working celebrities.

Soon, a professor from Peking University came to give a speech at the school and brought his brother's glasses. It turns out that Brother Glasses is not the smartest student, but he works hard and has made many great achievements. Hu Xiaoxiao was a little shaken. He always thinks that cleverness is more important than hard work. Then he began to think: Is hard work really more important than cleverness? The successful entrepreneur invited at the parent-teacher conference completely changed the fussy view. He shouted: I want to be a really smart and hardworking person!

Later, the children also learned that the mysterious man originally said that he was a math teacher named "cold noodle refrigerator", but in fact he had been silently helping the children. He is just cold on the surface, but warm inside.

Hu Xiaoxiao wrote in his diary: After so much experience, I finally believe that the really smart person is the one who knows how to work hard. What an important harvest this is! I believe that young readers will have a more correct understanding of hard work and cleverness after reading Hu Xiaoxiao's diary. May every child be a smart person who knows how to work hard.
