Zhan Tianyou, a pioneer of modern science and a famous engineer, faced with the difficult situation of lack of funds, technology and talents in China, was full of patriotic enthusiasm and was ordered to build the Beijing-Zhangjiakou Railway.

With the spirit of selflessness and hardship, he traveled all over the mountains between Beijing and Zhangjiakou. It took only 5 million yuan and four years to build the Beijing-Zhangjiakou Railway, which foreigners planned to spend 9 million yuan and took seven years to build.

All the foreign experts who came to visit were shocked and surprised. At that time, in recognition of Zhan Tianyou's achievements, an American university decided to award him a doctorate in engineering and invited him to attend the ceremony.

But Zhan Tianyou was responsible for the design of another railway, so he resolutely declined the invitation. His spirit of serving the country rather than the individual has won praise at home and abroad.

1950, mathematician Hua gave up his professorship in the United States and returned to the motherland. On his way home, he wrote an open letter to the students studying in the United States, in which he wrote: "In order to choose the truth, we should go back, and for the country and the nation, we should go back.

To serve the people, we should go back; Even for the sake of personal survival, we should go back as soon as possible, establish the foundation of work and strive for the construction and development of our great motherland. "

In order to get the opportunity of practice, he attended classes in the evening, studied for a doctorate, and worked as an intern in a bridge company during the day, drawing, cutting steel parts, riveting and painting by himself, and finally became a talent who knew both theory and technology.

Americans admire him very much, and letters of appointment were sent from all over the country, asking him to be an engineer. However, Mao Yisheng did not accept the invitation, but decided to return home. Someone in the United States advised him: "Science has no motherland and transcends national boundaries.

The contribution of scientists belongs to all mankind. Domestic conditions are poor, and your contribution will be even greater if you stay in the United States. Mao Yisheng replied: "Although science has no motherland, scientists have a motherland. I am a native of China, and my motherland needs me more. I want to go back to serve the motherland! "

19 19, Mao Yisheng returned home with all his skills and began to build bridges for the country. The magnificent Qiantang River Bridge in Zhejiang was designed and built by Mao Yisheng.
