Li Siguang lived in the countryside for nearly 14 years. He has been studying in a private school taught by his father since he was five or six years old, and he has to help his mother with firewood, rice, flour and water? Hard life has cultivated his hard-working spirit and stubborn character.

After the revolution of Taiping Heavenly Kingdom, Westernization Schools sprang up, and many new schools were established in Hubei, aiming at learning new things and being unconventional. Li Siguang was deeply attracted. He took the exam alone and was admitted with excellent results.

In the new school, he is eager to learn new knowledge. Because he won the first place in every exam, he was selected as a formal student in the province and sent to Japan to study shipbuilding.

Li Siguang stayed in Japan for seven years, where he joined the China League led by Dr. Sun Yat-sen. ..

In the second year after Li Siguang returned to China, the Revolution of 1911 broke out, and he took part in the defense of Hankou. As a newly appointed financial department of Hubei military government, he personally organized dockers and rickshaw pullers to transport arms and go to the front. Subsequently, he was elected as the Minister of Industry of Hubei Military Government. Just as Li Siguang was about to do something great, the Revolution of 1911 failed. He devoted himself to the research of science and technology and embarked on the road of saving the country through science. He went to study in England, first studying mining, then studying geology. He prayed that one day, he could see a politically clear world and contribute his youth and blood to the motherland.

Studying abroad is not easy. In order to maintain the rising tuition, Li Siguang went to work in the mine during the holidays. During his six years in Birmingham University, he not only achieved excellent academic results, but also mastered English, and obtained a bachelor's degree and a doctor's degree successively. After graduation, he politely refused a well-paid employment in a mine, accepted the invitation of Mr. Cai Yuanpei, returned to the motherland, and became a professor in the Geology Department of Peking University.

Li Siguang's famous saying

I am a descendant of the Chinese people, so I naturally want to dedicate all my knowledge to my dear motherland.

The true scientific spirit should be cultivated from correct criticism and self-criticism. Real scientific achievements must stand the test of facts. With such a double guarantee, we can do it with confidence and boldness, and will not dig the trap of arrogance.

Science respects facts and cannot make up excuses to attach a theory.

Science is an honest thing, which is accumulated by the labor and wisdom of many people.

If you don't doubt, you can't see the truth, so I hope everyone will be skeptical and don't be carried away by the established theory.

Truth, even if it only sees a glimmer of light, can't make its glory dim.
