The story of Li Siguang 100 words.

1. When Li Siguang was a child, his family was very poor, with seven brothers and sisters, and his grandfather was bedridden. My father is a teacher with a meager income, and my mother is farming alone, so life is very difficult. Li Siguang is the second child, very small, but very sensible. He usually feels sad when he sees his mother working alone, so he tries his best to help her with her work. As soon as it was dawn, he got up and filled the water tank. When you go up the mountain to cut wood, you always have to pick up a lot before you go home.

2. Li Siguang loves to use his brain since he was a child. He helped his mother cook, and stepped on the board with his foot, so that people could not step on it. He tied a rope to the pedal at the other end of the stone pestle. As soon as his foot stepped down, he pulled the rope with his hand, so that the stone pestle moved. He and his children went to the lotus pond to pick lotus roots. Most of his friends are laughing and playing. They can only pick a few broken lotus roots and take them home to eat for a long time. Li Siguang is very clever. He first stepped on the lotus root along the leaves, then carefully leaned out the direction of the lotus root with his feet, and then stepped on the mud a little according to its growth direction, and harvested a complete fresh lotus root.

In his early years, he made exquisite research on Odonata fossils and their stratigraphic stratification, put forward the existence of Quaternary glaciers in eastern China, established new concepts of geomechanics and tectonic system, established the concept of tectonic system, and founded geomechanics school. It is pointed out that the three subsidence zones of the new Cathaysian tectonic system have broad prospects for oil exploration, and a way to predict earthquakes by combining active tectonic research with in-situ stress observation is created.
