Li Siguang has made great contributions to my country's petroleum industry. After the founding of New China, the country was in urgent need of oil, but many foreign experts concluded that China had no oil. After long-term research, Li Siguang believed that there must be oil in our country's land. Based on his research results, our country has successively found Daqing Oilfield, Shengli Oilfield, Huabei Oilfield and other large oilfields, and has removed the label of "China is poor in oil".

If he had any questions, he went to ask his teacher and his dad to solve the problem. Later, he went to England. I went to study geology, and after returning to China, I conducted an investigation and solved my doubts.)
