What does the story of great scholar Zhang Heng tell future generations?

Zhang Heng was curious about everything in nature since he was a child. Dew-covered leaves in the morning, blazing sun at noon and shining stars at night all aroused his deep interest. Zhang Heng goes to the threshing floor with his mother every night. The children of other families are laughing and playing on the threshing floor, and you chase after me, and the laughter is full. Only Zhang Heng sat alone, looking at the unknown starry sky. His little hand kept moving. He said, "One, two, three …", as if enjoying the fun that others could not understand. Zhang Heng's mother thought that Zhang Heng was exhausted during the day, so she said to Zhang Heng, "Henger, if you are tired, go home and rest first." But Rolling ignored her mother, and her mother left without talking.

After a while, people on the threshing floor left one after another. An older child came over and patted Zhang Heng on the shoulder and said, "What are you doing? There will be no beans in the sky. " Zhang Heng said "Count the stars" without looking back. After Zhang Henggang finished, the child smiled: "You still count the stars, so have you counted them clearly?" Zhang Heng replied: "I counted more than a thousand, and I am almost finished." At this time, an old man next to him chimed in and said, "There are countless stars in the sky, so don't waste your energy." Zhang Heng interrupted the old man and said, "Impossible, there were only a thousand stars in the world that day, and they will be counted soon." As soon as Zhang Heng's father saw it, he immediately came to the circus: "How can you talk to grandpa like this? Apologize quickly. " . Zhang Heng hurriedly apologized in shame. Looking at Zhang Heng's awkward appearance, Zhang Heng's father understood his meaning: "The stars in the sky are also regular. Divide them into constellations for easy counting." Zhang Heng smiled thoughtfully and counted the stars as his father said, so he learned more knowledge.

In this story, Zhang Heng's persistent spirit of seeking knowledge is believed to have inspired many people.
