Part One (Paragraphs 1-9): "Where did the big stone that wrote about his hometown come from?" This question puzzled Li Siguang throughout his boyhood, and he never found the answer.

Part 2 (paragraphs 10-14): After growing up, Li Siguang finally figured out the origin of the giant stone after years of research.

Read carefully

Under the moonlight, Zhong Kui (Li Siguang's childhood name) and his children often played hide and seek on a large flat ground. Xiao Zhongkui likes to hide behind a big rock.

The topic at the beginning of the chapter naturally leads to the following, and it also shows that this big stone is often seen by children. It serves as a foil to show that Xiao Zhongkui can find problems in daily life and is diligent in thinking.

He asked his friends: "Hey, tell me, why is there such an unexpected big rock here?"

"Hahaha!" The friends burst into laughter, "Where did the stone come from? It's already there!"

The language description shows Xiao Zhongkui's valuable qualities of being diligent in thinking and good at asking questions.

"No one can explain it clearly." Xiao Zhongkui felt dissatisfied, "How did it come from?"

Li Siguang has been different since he was a child. He has a spirit of asking questions to the end. His friend, Chen Er's father, his father's answer obviously cannot satisfy Li Siguang's curiosity.

A question that arose when you were a child has finally found a scientific answer after a quarter of a century. What enlightenment did you get from it?

First, we must learn from Li Siguang’s spirit of diligent observation, good thinking, willingness to seek knowledge, courage to explore, and perseverance.

The second is to let us understand that curiosity is the premise and foundation of invention and creation. Only by thinking diligently and exploring more than asking questions can we create results with more scientific value.
