Regardless of fame and fortune for the country: Zhan Tianyou, a pioneer of modern science and a famous engineer, faced with the difficult situation of domestic lack of funds, technology and talents, 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 and spent only 5 million yuan. In 4 years, the Beijing-Zhangjiakou Railway was completed, which required foreigners to invest 9 million yuan and took 7 years. 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.

2. Hua.

Hua resolutely returned to China: After the July 7th Incident, the great mathematician Hua returned to War of Resistance against Japanese Aggression's motherland, not for money or for a degree, and took an active part in the anti-Japanese national salvation movement after returning home.

1950, he became an internationally renowned first-class mathematician and was hired as a tenured professor by the University of Illinois, but he resolutely led his family back to the newly liberated motherland.

3. Zheng Chenggong

Zheng Chenggong Recovered Taiwan Province Province: As early as 1624, Dutch colonialism invaded China's territory, Taiwan Province Province, and exercised extremely brutal rule. The people of Taiwan Province Province fought bravely against the invaders.

166 1 year, Zheng Chenggong, who led the anti-Qing struggle in the southeast coast, led more than 350 warships and more than 25,000 soldiers and surrounded Taiwan Province Province. After nine months of fierce fighting, the Dutch Governor was forced to sign the surrender, and led the defeated troops to roll out of Taiwan Province Province. Taiwan Province Province has returned to the embrace of the motherland.

4. Wen Tianxiang.

In the first year of Deyou, Mongolian fighters were as devastating as Lin 'an. Wen Tianxiang, then governor of Ganzhou, led troops and spent all his military expenses. His friend advised him: You should use this rabble of more than 10,000 people to resist the three armed forces of the Yuan Dynasty, which is different from chasing sheep and killing tigers.

Wen Tianxiang said: What I hate most is that once the country is in an emergency, it recruits troops from all over the world, and no one rides into the customs. The reason why I overreached and prepared to generalize is to make loyal ministers and benevolent people in the world rise up in the news. It is possible to save the country only if the righteous seek to establish themselves and many people work hard.

After years of tenacious resistance, Wen Tianxiang was defeated and captured. Zhang Hongfan, the general of the Yuan Dynasty, forced him to write a letter asking for Zhang Shijie, and Zhang Shijie continued to resist in Jianshan. He resolutely refused. Kublai Khan, the emperor of the Yuan Dynasty, hoped to persuade Wen Tianxiang to fight against the Song Dynasty.

Wen Tianxiang died calmly at the age of 47. His heroic heart will remain in history forever.
