Mao Qian, Mao Yisheng's grandfather, is an influential water conservancy expert in modern Chinese history. My humble opinion on water conservancy, which I wrote before my death, is still treasured in Beijing Library. He has seen the mountains and rivers of the motherland all his life and his thoughts are radical. He devoted himself to establishing schools and newspapers. In addition to my humble opinion on water conservancy, he also wrote books such as Collected Works of Flying Mountain and Poems of Flying Mountain.

When my grandfather witnessed the corruption of the Qing government and ceded land for compensation, he was very sad, but he could not change it. He is addicted to poetry and wine all day. Mao Yisheng's birth gave him great hope for his grandson.

So how to create a good study and living environment for future generations is in front of my grandfather: should I stay in Zhenjiang or move elsewhere? Determine the relocation, where to move? Grandpa thought twice and finally decided to move to Nanjing, where culture and education are very developed.

After his family moved to Nanjing, Mao Yisheng began to study at school. He studies harder. One day at dinner, Mao Yisheng disappeared, and the whole family was in a hurry. Everyone shouted and looked separately, but no one was found.

Later, my grandfather found a faint light in the attic. When he went up, Mao Yisheng was absorbed in reading ancient Chinese in the attic! Grandfather was very happy. Instead of blaming him, he praised him and promised, "I will teach you well when I have a holiday."

In order to exercise his memory, Mao Yisheng stood by the river every morning reciting ancient poems and prose. On the river, sails are sailing and fishing songs are bursting, but he can turn a blind eye, listen but not smell, and completely immerse himself in the ocean of knowledge he needs.

Over time, Mao Yisheng not only memorized many ancient poems and prose, but also effectively enhanced his memory. One day, my grandfather copied ancient prose with a brush, and Mao Yisheng stood beside him. My grandfather put down his brush and recited a copy of Kyoto Fu word for word.

Mao Yisheng not only can recite ancient poems and prose, but also is not afraid of boredom and can recite abstract figures. Once, he read an article, wrote the approximate value of pi to 100 after the decimal point, and decided to memorize these boring numbers to exercise his memory.

So he memorized this long list of numbers paragraph by paragraph: 14, 15, 92, 65, 35, 89, 79, 32, 38, 46, 26, 43, 38 ... Although it is difficult to remember, it ranges from a dozen decimal places to dozens of digits.

On his eightieth birthday, he can miraculously recite the number 100 recorded in his childhood. Influenced by his grandfather in childhood, Mao Yisheng developed many good study habits.

Second, the riddle of Lantern

Lantern Festival once a year? Grandfather gave Mao Yisheng a merry-go-round. At first, when Mao Yisheng saw this lamp, it was just for fun. Looking at him, he felt very strange: "This' lamp' really walks!"

Through careful observation, he understood the principle, so he found another candle from home and put it on the wheel. After lighting, the "lantern" really turned faster, and the success of the "experiment" made him elated.

When he grew up, Mao Yisheng once recalled, "Grandpa bought me lanterns, which made me feel that there are too many mysterious facts in the world. To discover these mysteries, we must explore. " From then on, Mao Yisheng made up his mind to be an explorer to explore the infinite mysteries of the world.

My uncle gave it to me for my birthday.

Among Mao Yisheng's parents, there is another person he will never forget, and that person is his uncle.

On Mao Yisheng 10 birthday, his uncle took an uncolored atlas of the world from his pocket and told him, "Take a good look at this book! You can see the world here! " Mao Yisheng took over his uncle's atlas and felt very happy.

A world atlas, as long as you open it, you can see the whole world. It is incredible that the vast land and sea can be held in your hands so easily.

In Mao Yisheng's mind, among many gifts, only the gift from my uncle is the most precious. It was his uncle's atlas that opened young Mao Yisheng's eyes. How much he hopes to visit all parts of the country and the world one day.

The atlas sent by my uncle not only opened young Mao Yisheng's eyes, but also made him understand the whole world from the beginning and set up a correct world outlook.

Fourth, exercise and fitness.

As a teenager, Mao Yisheng was very keen on running in the morning, playing basketball and other fitness activities, especially playing football on a wide field. As a football player, he often takes part in fierce football matches. When he is wearing a football sportswear, he is dignified and full of pride.

When he plays forward, he runs flexibly, sometimes circuitous and sometimes interspersed. He often walks to the opponent's door, lifts his foot to shoot and score goals, and becomes the inseparable "shooter" of the school football team.

Soon, Mao Yisheng just entered Tangshan Road Mine School, and a bad cold complicated with tonsillitis kept him in bed for several days. After he recovered from his illness, he suddenly found that taking a cold bath, like exercise, can keep fit.

So every morning he insisted on washing his face with cold water to improve and improve his body's cold resistance. Especially in the dead of winter, after washing your face with cold water, warm current spreads all over your face and hands. He thinks that this not only exercises your cold resistance, but also sharpens your will. In the afternoon, he still bathed in cold water. For many years, Mao Yisheng let his skin enjoy healthy happiness in cold water massage.

Since then, he has rarely caught a cold for decades. The cold bath he insisted on every day has brought vigorous energy to his scientific research, teaching, writing and social activities for decades.

Verb (abbreviation of verb) the tragedy of Dragon Boat Festival.

In Mao Yisheng's hometown, dragon boat races are held on the Qinhuai River every year. Once when people were happily watching the game, the bridge suddenly collapsed and many people fell into the river, causing many casualties.

This incident made Mao Yisheng extremely painful, and then a series of thoughts rolled in his mind: Why did the bridge collapse? Can you build a bridge that will bear great pressure and will not collapse for a long time? It was the collapse of Qinhuai River Bridge that made Mao Yisheng make up his mind in his youth.

In the future, universities must learn civil engineering and build a bridge that will never collapse for the country to avoid such a tragedy. From then on, Mao Yisheng began a hard journey to the peak of bridge career on his own life.
