After a while, the people on the threshing floor gradually left. An older child came over and patted Zhang Heng on the shoulder and said, "What are you doing? Beans don't fall from the sky." Zhang Heng said without looking back, "Count the stars." As soon as Zhang Heng finished speaking, the child laughed loudly: "You are still counting stars, have you counted them clearly?" Zhang Heng replied: "I have already counted more than a thousand stars, and I am almost done." At this time, an old man next to him interjected: "There are countless stars in the sky, so don't waste your efforts." Zhang Heng interrupted the old man and said: "Impossible, there are only more than a thousand stars in that sky, and they will be counted soon." After seeing Zhang Heng's father, he immediately came over to smooth things over: "How could you talk to grandpa like this? Apologize quickly." Zhang Heng apologized quickly in shame. Seeing Zhang Heng's hesitant expression, Zhang Heng's father understood what he meant and said: "The stars in the sky also have regular patterns. It is necessary to divide them into constellations to make it easier to count them." Zhang Heng smiled thoughtfully and counted the stars as his father said, and he learned more knowledge.
