The boy knows the ambition of a strong man. Who does a boy refer to? Who does a strong man refer to?

Ban Chao, courtesy name Zhongsheng, was born in Pingling County, Fufeng County, and was the youngest son of Ban Biao, the magistrate of Xu County. He is very ambitious and informal, but has good moral character. He often does hard and menial work at home and does not consider it a shame to do hard and low-level things. Ban Chao is very eloquent and has read many books extensively. In the fifth year of Yongping reign of Emperor Ming of the Han Dynasty, Ban Chao's elder brother Ban Gu was recruited by the imperial court to serve as a school secretary, so he and his mother followed his brother to Luoyang. Because his family was poor, he was often hired by the government to make a living by copying books, which was very hard for a long time. He once stopped working, threw the pen aside and sighed: "As a man, although he has no outstanding strategic talents, he should always learn from Fu Jiezi and Zhang Qian who have made great achievements abroad, and be awarded the title of marquis. How can he always do this ink?" What's the point of making a living?" The colleagues around him laughed at him. Ban Chao then said: "How can ordinary people understand the ambition of a man with lofty ideals?" So the boy refers to those colleagues who laugh at him, and the strong man is a metaphor for himself.
